1933–1935 Dodge Second Series Truck: HC and KC Flathead-Six Chassis
Dodge sold its HC light-duty commercial vehicles for 1933 and followed them with the KC series for 1934 and 1935, all before the Job-Rated program appeared for 1939. These trucks used Dodge or Chrysler-family L-head six-cylinder engines, three-speed manual transmissions, rear-wheel drive, beam front axles, leaf springs, and four-wheel hydraulic drum brakes.
Best known for bringing six-cylinder power and hydraulic braking to an affordable Depression-era working truck, the HC and KC models also introduced the proportions that collectors now associate with early streamlined Dodge pickups: a long hood, upright steel cab, separate rear fenders, running boards, and a compact cargo box.
The Second Series designation is most useful as a family or generation description rather than as a badge found on every truck. Identification rests more securely on the HC or KC model designation, the serial number, engine number, wheelbase, surviving body hardware, and documentary evidence. That distinction matters because many restored examples combine cabs, beds, engines, axles, and sheet metal gathered from several commercial models.

The HC and KC codes are more meaningful than the broad Second Series label when buying parts or checking a restoration. A component advertised merely for a 1933–1935 Dodge truck may belong to another wheelbase or payload class, even when its general appearance is similar.
Why the Second Series Truck Matters
By 1933, Chrysler had owned Dodge Brothers for five years. Dodge retained a well-established commercial-vehicle identity, while Chrysler engineering gave its trucks access to proven six-cylinder engines and hydraulic braking at a time when Ford still relied on mechanically actuated brakes. For an operator hauling produce, tools, or shop supplies, those were practical differences rather than advertising abstractions.
The HC and KC also mark Dodge's move toward a more integrated visual language. Their radiator shells, hood louvers, crowned fenders, and steel cabs looked less like separate pieces assembled around a commercial chassis than the square-bodied trucks of the preceding decade. The KC's longer wheelbase and revised front-end treatment made the proportions more settled, while retaining the narrow cab and freestanding headlamps expected of an early 1930s truck.
These models deserve separate treatment from the later Job-Rated trucks because Dodge had not yet organized its range under the payload-specific 1939 marketing and engineering program. Parts books, serial records, wheelbase measurements, and individual model codes remain the proper way to classify them.
Historical Context and Development
The HC arrived during the deepest years of the Great Depression, when commercial buyers placed operating cost and durability ahead of novelty. Chevrolet competed with overhead-valve six-cylinder trucks, Ford offered four-cylinder and flathead V8 power in its commercial range, and International Harvester sold directly to agricultural and industrial users. Dodge answered with a relatively conservative chassis carrying a smooth, low-speed six and hydraulic brakes.
The engineering priorities were straightforward: strong torque at ordinary road speeds, simple servicing, a rigid frame, generous suspension travel, and body choices that could serve retailers, tradesmen, farms, and municipal fleets. Motorsport and homologation played no role. These were working vehicles, frequently ordered as chassis-cabs and completed with bodies suited to a specific trade.
For 1934, the KC series revised the light-duty formula with a longer wheelbase and the larger 201.3-cubic-inch six commonly listed in factory and specialist references. The styling became more streamlined without sacrificing the removable fenders, running boards, exposed headlamps, and bolt-on cargo body that made collision and work damage easier to repair.
Design and Commercial Bodywork
A surviving pickup has a compact cab with a nearly vertical rear panel, a shallow windshield, separate front and rear fenders, and a wood-floored steel cargo box. The radiator grille dominates the front view, while the tall hood and narrow track produce the upright stance typical of a prewar commercial vehicle.
Panel bodies, stake racks, flat platforms, and locally constructed service bodies complicate modern identification. A non-pickup body is not automatically incorrect, but its age, mounting method, construction, and relationship to the chassis should be documented before it is presented as factory-supplied equipment.
Engine and Drivetrain
The principal engine was a water-cooled inline six with its camshaft and valves mounted in the cylinder block. This L-head, or flathead, arrangement produced a low engine profile and simplified cylinder-head construction. It also favored moderate compression and low-speed flexibility over high-rpm breathing.
A single carburetor supplied the mixture through a conventional intake manifold. Ignition used a distributor, coil, spark plugs, and a six-volt electrical system. Cooling depended on a belt-driven fan, water circulation, and a front-mounted radiator, while pressure lubrication served the engine's major bearings according to Chrysler practice of the period.
Exact carburetor, distributor, generator, and starter applications should be confirmed against a model-specific parts book. Service replacements accumulated quickly on commercial vehicles, and several units that function correctly are not necessarily correct for the truck's assembly period.
The table lists the specifications most consistently associated with light-duty HC and KC trucks. Published horsepower ratings can differ with compression ratio, market, and rating convention, so they should not be used alone to identify an engine.
| Specification | 1933 HC | 1934–1935 KC |
|---|---|---|
| Configuration | Inline six, L-head | Inline six, L-head |
| Displacement | Approximately 190 cu in | 201.3 cu in, commonly listed |
| Fuel system | Single carburetor | Single carburetor |
| Factory-rated output | Approximately 70 bhp, commonly published | Approximately 75 bhp, commonly published |
| Cooling | Liquid cooled, belt-driven fan | Liquid cooled, belt-driven fan |
| Clutch | Single dry plate | Single dry plate |
| Transmission | Three-speed manual | Three-speed manual |
| Final drive | Rear differential; ratio varied by application | Rear differential; ratio varied by application |
The larger KC engine did not transform the truck into a high-speed vehicle. Its useful advantage lay in pulling from low and medium engine speeds with fewer downshifts. Rear-axle gearing remained selected for load-carrying work, which limited comfortable sustained speed compared with later pickups.
Chassis, Suspension, Steering, and Brakes
A separate steel ladder frame carried the cab, front sheet metal, drivetrain, and commercial body. The front suspension used a solid beam axle on semi-elliptic leaf springs, while the live rear axle was also located by leaf springs. This layout tolerated poor roads, payload, and rough job-site use, but it transmitted unsprung-mass movement directly into the frame and steering.
Steering was manual through a steering box and mechanical linkage. Four-wheel hydraulic drum brakes were a notable Dodge feature in this class, although their present-day effectiveness depends heavily on correct wheel-cylinder condition, hose integrity, drum diameter, shoe arc, adjustment, and the absence of fluid contamination.
The following dimensions and equipment describe the common light-duty chassis. Commercial bodies and heavier truck models require separate specifications.
| Item | HC | KC |
|---|---|---|
| Model years | 1933 | 1934–1935 |
| Common light-duty wheelbase | 111.25 in | 116 in |
| Frame | Separate steel ladder frame | Separate steel ladder frame |
| Front suspension | Beam axle, semi-elliptic leaf springs | Beam axle, semi-elliptic leaf springs |
| Rear suspension | Live axle, semi-elliptic leaf springs | Live axle, semi-elliptic leaf springs |
| Steering | Manual steering box | Manual steering box |
| Brakes | Four-wheel hydraulic drums | Four-wheel hydraulic drums |
| Electrical system | Six volt | Six volt |
Wheelbase is an effective first check because it cannot be disguised as easily as bolt-on sheet metal. It is not sufficient by itself, however, since Dodge produced several commercial chassis and owners routinely adapted bodies to suit later work.
Driving Experience and Handling Dynamics
An HC or KC in sound mechanical condition starts with the deliberate rhythm expected of a low-compression flathead six. Throttle response is progressive rather than sharp, and useful pull arrives before high engine speed becomes necessary. A properly adjusted carburetor and ignition system should allow clean acceleration without persistent hesitation, exhaust popping, or clouds of fuel-rich smoke.
The long gear lever and three-speed transmission reward unhurried shifts. First gear is primarily for starting under load or negotiating steep ground, while second and third handle most road work. Worn selectors, clutch drag, and tired engine mounts can make the change feel far worse than Dodge intended.
Manual steering is heavy at parking speed and lightens once the truck is moving. A sound front axle should track predictably, but excessive kingpin wear, loose tie-rod ends, incorrect toe, deteriorated spring shackles, or mismatched tires can produce wander. The beam axle also reacts noticeably to potholes and corrugations.
Leaf springs selected for cargo capacity give an empty truck a busy ride. Adding a modest load settles the rear suspension, though tall bodywork and period tires still encourage measured cornering. Hydraulic brakes provide a useful advantage over contemporary mechanical systems, but they lack modern self-adjustment, fade resistance, and pedal assistance.
Identification and Originality
These trucks predate the standardized 17-character vehicle identification number by several decades. Collectors must work from the original serial plate or chassis record, engine number, model designation, wheelbase, body construction, and period registration documents. A recently stamped tag should never be treated as conclusive without supporting evidence.
The engine number should be examined on its factory-machined stamping surface, with its typeface and surface condition compared with known original examples. Many trucks received replacement engines during their working lives. That does not make one unusable or historically worthless, but it affects any claim that the power unit is original to the chassis.
Modern matching-numbers language needs restraint here. The most convincing truck is one whose serial and engine information agrees with surviving factory or period ownership records. A numerically plausible engine installed decades later is not the same thing as a documented original assembly.
Body, Trim, and Hardware
Correct hood panels, grille shell, radiator support, fenders, splash aprons, running boards, cab mounts, headlamp hardware, door mechanisms, and bed dimensions deserve close inspection. Cabs and pickup boxes were frequently transferred between trucks, while rear fenders and tailgates were vulnerable to work damage. Hot-rod projects have also supplied the market with original sheet metal removed from otherwise complete chassis.
Door fit often reveals weakened cab wood, fatigued mounting points, prior collision damage, or an incorrectly mounted body. The bed floor was wood, and restoration quality varies from carefully fitted boards and correct hardware to furniture-grade material installed without regard to original dimensions or fastening patterns.
Paint, Upholstery, and Date-Sensitive Components
Factory colors should be researched through year-specific Dodge sales literature and surviving paint-chip references. A color offered by Dodge in another year is not automatically correct for an HC or KC. Engine enamel, chassis black, wheel color, grille finish, pinstriping, and cab interior treatment should receive the same scrutiny as the exterior body color.
Carburetors, distributors, generators, starters, gauges, wheels, lamps, and fasteners are commonly replaced. Casting dates and manufacturer tags can support a restoration, but they must agree with the truck's assembly period and model application. Owners should retain photographs and invoices for original parts even when those parts are too worn for continued service.
Variant and Model Breakdown
HC and KC identify the principal light-duty groups discussed here, not trim levels in the modern passenger-car sense. Body type, wheelbase, payload classification, and customer-specified commercial equipment created most of the meaningful variation.
| Variant / Code | Years | Engine / Output | Market | Key Difference |
|---|---|---|---|---|
| HC light-duty commercial chassis | 1933 | Approximately 190 cu in L-head six; about 70 bhp commonly listed | North America | Earlier short-wheelbase form, commonly encountered as a pickup or commercial chassis |
| KC light-duty commercial chassis | 1934–1935 | 201.3 cu in L-head six; about 75 bhp commonly listed | North America | Longer common light-duty wheelbase and revised styling |
| Pickup body | 1933–1935 | Matched to HC or KC chassis | Retail, farm, and trade use | Open cargo box with separate rear fenders |
| Panel and closed delivery body | 1933–1935 | Matched to chassis specification | Urban delivery and service fleets | Enclosed cargo body; surviving body details require individual documentation |
| Chassis-cab, platform, or stake body | 1933–1935 | Engine and gearing varied by chassis class | Agricultural, industrial, and municipal work | Commercial body selected or constructed for the operator |
Exact production totals by light-duty code and body style are not consistently documented in readily available period records. Claims that a particular body is one of only a handful should be supported by factory data, a recognized registry, or an unbroken documentary history.
Performance and Dimensional Specifications
Factory literature emphasized payload, wheelbase, engine output, and commercial usefulness rather than acceleration. Reliable period 0–60 mph, quarter-mile, and independently measured top-speed figures are not consistently available for the family, so modern estimates have been excluded.
| Measurement | 1933 HC | 1934–1935 KC |
|---|---|---|
| Common light-duty wheelbase | 111.25 in | 116 in |
| Engine displacement | Approximately 190 cu in | 201.3 cu in |
| Published engine output | Approximately 70 bhp | Approximately 75 bhp |
| Forward ratios | Three | Three |
Overall length, width, body weight, rear-axle ratio, and payload depend on the specific chassis and commercial body. A pickup, panel delivery, and stake truck should not be assigned the same dimensions merely because all three use related front sheet metal.
Compared With Related Dodge Trucks
HC Versus KC
The clearest comparison is between the 1933 HC and the 1934–1935 KC. The HC uses the shorter common light-duty wheelbase and the smaller six generally listed at approximately 190 cubic inches. The KC is associated with a 116-inch light-duty wheelbase, the 201.3-cubic-inch engine, and updated front-end styling.
They share the same basic engineering grammar, including a separate frame, beam front axle, leaf springs, hydraulic drums, manual gearbox, and rear-wheel drive. That similarity encourages parts mixing, which makes serial evidence and careful measurement essential during identification.
Second Series Versus Earlier Dodge Brothers Trucks
Earlier Dodge Brothers commercial vehicles generally carried squarer bodies and styling derived more directly from late 1920s practice. The HC and KC appear lower and more cohesive, with rounded fenders and a stronger relationship between the grille, hood, cowl, and cab.
Second Series Versus the 1939 Job-Rated Range
The 1939 trucks belong to a later engineering and marketing system. Job-Rated grouped engines, clutches, transmissions, axles, springs, brakes, wheels, and frames according to intended service. Applying the Job-Rated label to a 1933–1935 truck is historically inaccurate, even if the phrase appears in an advertisement or auction description.
Ownership and Restoration Notes
Routine mechanical work is manageable because the flathead six, manual gearbox, beam axle, and drum brakes are conceptually simple. The challenge lies in finding correct components and recovering dimensions or finishes lost through decades of repair. Mechanical simplicity should not be confused with cheap restoration.
Cooling systems need close attention. Sediment in the block and radiator, a worn water pump, poor fan-belt alignment, damaged water passages, and incorrect ignition timing can all create overheating. A rebuild should include inspection for cylinder wear, cracks, valve-seat damage, oil-pressure loss, crankshaft condition, and corrosion around the water jacket.
Gearboxes may suffer from worn bearings, damaged gear teeth, tired selectors, and leaking seals. Rear axles deserve checks for bearing noise, excessive backlash, leaking pinion seals, and an unsuitable ratio installed during later use. Clutch chatter may originate in the driven plate, pressure plate, mounts, flywheel surface, linkage, or oil contamination.
Rust and Structural Deterioration
Inspect the lower cowl, cab corners, door bottoms, windshield surround, floor edges, seat base, roof seams, fender mounting points, splash aprons, running-board brackets, and the junction between the cab and frame. Mud retained behind fenders or brackets can corrode metal from both sides. Poorly executed patch panels often conceal damage rather than restore the original structure.
The frame should be checked for cracks near spring hangers, steering-box mounts, crossmembers, and rear body mounts. Look for distortion caused by overloading, collision repairs, towing equipment, or a later engine conversion. Rivets replaced indiscriminately with hardware-store bolts are a warning that previous work may not preserve structural alignment.
Parts Availability and Restoration Strategy
Engine service parts, bearings, brake linings, electrical components, and carburetor kits are generally easier to source than model-specific sheet metal, trim, gauges, and commercial-body hardware. Reproduction rubber, wiring, glass, bed wood, and some maintenance pieces can reduce the burden, but fit and historical accuracy differ among suppliers.
Before disassembly, photograph serial plates, fasteners, wiring routes, wood dimensions, body shims, paint layers, upholstery remnants, and component tags. Early commercial vehicles were often repaired pragmatically, so the truck itself may preserve details absent from general restoration manuals.
Buyer and Inspection Points
A useful inspection separates cosmetic condition from identity and mechanical integrity. Fresh paint adds little if the chassis code, engine, wheelbase, and body construction do not support the seller's description.
| Area | What to Check | Why It Matters |
|---|---|---|
| Serial identification | Original tag, fastening method, number style, title, registration history, and model designation | A replaced or unsupported identity can create legal, historical, and valuation problems |
| Wheelbase and frame | Measure wheelbase; inspect rails, crossmembers, rivets, spring hangers, and steering-box mounts | Confirms chassis type and reveals overloading, collision damage, or later modification |
| Engine | Number stamping, cold oil pressure, smoke, coolant contamination, compression, cracks, and abnormal bearing noise | Replacement engines are common, and a full flathead rebuild can exceed the cost suggested by its simple design |
| Cooling system | Radiator core, water pump, block sediment, fan, belt alignment, hoses, and evidence of chronic overheating | Restricted coolant passages can persist after superficial radiator work |
| Transmission and axle | Clutch release, gear engagement, bearing noise, axle backlash, leaks, and driveline vibration | Correct gears and internal parts are less convenient to source than routine service items |
| Hydraulic brakes | Master and wheel cylinders, hoses, steel lines, drum condition, adjustment, and fluid leakage | Long storage can corrode the entire system, even when the pedal initially feels firm |
| Cab structure | Door gaps, hinges, lower cowl, floors, cab mounts, windshield frame, roof seams, and concealed filler | Correcting a twisted or heavily patched cab requires extensive fitting and fabrication |
| Pickup bed or commercial body | Dimensions, mounting points, floor structure, fenders, tailgate, stake pockets, and age of construction | A later reproduction or improvised body materially changes originality |
| Electrical system | Six-volt components, cable gauge, generator output, starter condition, grounding, and conversion work | Poor cables and grounds are often mistaken for a weak six-volt design |
| Trim and instruments | Gauge faces, switches, lamps, handles, grille pieces, wheels, and hard-to-find mounting hardware | Missing model-specific details can consume more time than basic mechanical rebuilding |
A running, incomplete truck can be a harder project than a non-running but unmodified example. Price the missing grille parts, gauges, bed hardware, fenders, wheels, lamps, and serial documentation before treating the engine's ability to start as proof of value.
Collector and Market Relevance
Collectors generally favor complete pickups with a defensible HC or KC identity, correct-style flathead power, uncut frames, intact front sheet metal, and a cargo box that is original or accurately reconstructed. Documented commercial bodies also have appeal, particularly when period lettering, fleet records, or ownership history survive.
Rarity alone does not determine desirability. A heavily modified truck with an uncertain chassis identity may be less compelling than a more common pickup retaining its original cab, engine architecture, suspension, brakes, and commercial hardware. Quality of metalwork is especially important because the visual simplicity of these bodies exposes uneven door gaps, incorrect crown, and poorly shaped fenders.
Restored examples appear at specialist auctions, but much of the market remains within prewar Dodge clubs, vintage-truck groups, estate sales, and private collections. Collectors tend to distinguish stock restorations from hot rods, since engine swaps, frame boxing, independent front suspension, altered ride height, and widened wheels remove much of the original driving and engineering character.
Cultural and Commercial Legacy
The HC and KC were not racing or media creations. Their history was written through delivery routes, farms, garages, municipal fleets, and trades that needed a compact truck capable of carrying a useful load without the fuel consumption or bulk of a heavier chassis.
Surviving examples often became hot-rod material because their separate fenders, narrow cab, upright grille, and short pickup body suit traditional custom proportions. That aftermarket history has preserved some sheet metal while also reducing the pool of intact chassis. Stock restorers now compete for the same grilles, cabs, beds, and fenders once removed during customization.
Within Dodge club culture, the HC and KC provide a direct link between Dodge Brothers commercial vehicles and Chrysler's later Job-Rated trucks. Their appeal comes from identifiable engineering differences, not from a retrospective performance narrative they never possessed.
Frequently Asked Questions
What engine did the 1933 Dodge HC truck use?
The 1933 HC light-duty truck is commonly documented with an approximately 190-cubic-inch L-head inline six rated near 70 bhp. Engine numbers and casting details should still be checked because replacement Chrysler-family flathead sixes are common.
What changed on the 1934–1935 Dodge KC truck?
The KC is commonly associated with a 116-inch light-duty wheelbase, revised styling, and a 201.3-cubic-inch L-head six listed near 75 bhp. It retained a separate ladder frame, beam front axle, leaf springs, hydraulic drum brakes, and a three-speed manual transmission.
Is the Dodge Second Series Truck the same as a Job-Rated Dodge?
No. The HC and KC trucks belong to Dodge's pre-Job-Rated era. Dodge introduced the Job-Rated range for 1939, with components selected and marketed according to a truck's intended payload and service.
How can an HC be distinguished from a KC?
Start with the serial identification, model code, engine number, and wheelbase. A common light-duty HC wheelbase is 111.25 inches, while the corresponding KC is commonly listed at 116 inches. Styling and engine displacement provide supporting evidence, but bolt-on parts alone are not conclusive.
Are parts available for 1933–1935 Dodge trucks?
Routine engine, brake, bearing, ignition, wiring, glass, rubber, and carburetor-service parts are generally more accessible than original sheet metal, gauges, grille pieces, lamps, bed hardware, and trim. Some reproduction parts exist, but fit and factory accuracy should be verified before purchase.
What are the most serious restoration problems?
Major concerns include cab rust, cracked or altered frames, missing identification, worn kingpins and steering linkage, cooling-system sediment, damaged hydraulic-brake components, non-original commercial bodies, and incomplete trim. A truck missing rare body pieces can cost more to finish than a complete but mechanically tired example.
What makes an HC or KC Dodge pickup collectible?
Collectors value the pre-Job-Rated engineering, Dodge flathead-six drivetrain, hydraulic brakes, compact early 1930s styling, and scarcity of complete unmodified survivors. Original serial evidence, an uncut chassis, correct body proportions, and documented restoration work carry more weight than cosmetic gloss alone.
Collector Takeaway
The 1933–1935 Dodge Second Series Truck matters because it records how Dodge built a practical light commercial vehicle before Job-Rated standardization. The HC and KC combined six-cylinder power, hydraulic brakes, simple beam-axle construction, and repairable bolt-on bodywork at a time when every gallon of fuel and every hour off the road affected a business.
The best survivor is not necessarily the most polished. It is the truck whose HC or KC identity can be defended, whose frame and cab remain structurally honest, and whose flathead drivetrain still explains how a Dodge commercial vehicle worked in the Depression years. Preserve those elements, and the result is far more valuable historically than another early pickup stripped of its chassis and reduced to a period-shaped hot rod.
