What is the difference between a 1949 Chevy 3600 and a 3100?
The core difference is payload capability: the 3600 is Chevrolet’s 3/4-ton heavy‑duty pickup, while the 3100 is the lighter 1/2-ton variant; they share the same cab and many parts but differ in chassis strength, wheelbase and bed options, and intended use.
Overview of the Advance-Design era pickups
In 1949, Chevrolet’s Advance-Design trucks carried familiar styling and a common cab, with model numbers that signaled payload potential. The 3100, 3600, and 3800 namesdenote different weight ratings rather than distinct body shapes. While the cabs look alike and many components are interchangeable, the chassis and underpinnings diverge to reflect the loads each truck was built to carry. This article focuses on how the 3100 (half-ton) and 3600 (three-quarter-ton) differ in capability and configuration.
Key differences in capability and design
The following points summarize the main mechanical and practical distinctions you’re likely to notice between the 3100 and 3600 models:
- Payload rating and GVWR: The 3100 is the lighter 1/2-ton class, while the 3600 is the heavier 3/4-ton class, designed to carry larger loads with a higher gross vehicle weight rating.
- Chassis and suspension: The 3600 uses heavier-duty rear and front axles with stiffer leaf-spring packs to handle heavier payloads; the 3100 employs lighter components suited for everyday light-duty use.
- Wheelbase and bed configurations: The 3600 often offered longer wheelbase options and longer bed configurations to maximize cargo capacity, whereas the 3100 typically provides shorter bed arrangements for tighter spaces.
- Powertrain basics: In 1949 both models commonly used Chevrolet’s inline-six engines and a manual transmission; there was no factory V8 option in that year, and most drivetrains were common across the lineup.
- Market positioning and use cases: The 3100 targetted private buyers and light commercial work; the 3600 was oriented toward fleets, farms, and tasks requiring more robust load handling.
The differences above reflect how Chevrolet differentiated the two models within the same generation, maintaining a shared cab while tailoring the chassis to different hauling needs.
Mechanical and body details
From a restoration or purchase perspective, the cab and interior generally look the same across the two models, but the frame, axles, and springs are the telltale signs of the 3600’s heavier duty nature. Inspecting the rear axle, leaf springs, and frame cutouts can help identify a 3600 versus a 3100 when a vehicle is not clearly labeled by model year.
What to look for when shopping
When evaluating a 1949 Chevy pickup, verify the model through the data plate and correlate it with the visible chassis and bed configuration. Look for:
- GVWR and payload rating on the data tag or title
- Rear and front axle condition and spring packs
- Wheelbase and bed length indicators (longer configurations suggest 3600)
- Engine and transmission type consistent with 1949 inline-six and manual gear choices
These checks help confirm whether a truck is a 3100 or a 3600 when documentation is incomplete or ambiguous.
Summary
In essence, the 1949 Chevy 3100 and 3600 share the same vintage design and cab, but the 3600 is the heavier-duty, 3/4-ton variant with stronger axles, stiffer springs, and longer wheelbase/bed options to handle bigger loads. The 3100 offers lighter payload capability, typically with shorter bed configurations and lighter suspension. The practical difference comes down to load capacity and the corresponding chassis choices; buyers and restorers should verify GVWR, axle and spring setup, and wheelbase to distinguish between the two.
Closing note
Both models represent Chevrolet’s early postwar approach to a versatile light-truck lineup. Understanding the payload-focused distinctions helps buyers determine which model best suits expected use, whether it’s daily driving with occasional hauling or serious farm and fleet work.
How much is a 1949 Chevy 3100 worth?
Typically, you can expect to pay around $23,900 for a 1949 Chevrolet Series 3100 1/2 Ton in good condition with average spec. The highest selling price of a 1949 Chevrolet Series 3100 1/2 Ton at auction over the last three years was $143,000.

What is the difference between a 3100 and a 3600 Chevy truck?
Late 1949 - Hood side emblems no longer read "Thriftmaster" or "Loadmaster", but are now numbers that designate cargo capacity: 3100 on 1⁄2 ton, 3600 on 3⁄4 ton, 3800 on 1 ton. Serial number codes remain the same as on early 1949.
