What is the width of the axle on a 1956 Chevy truck?
For a 1956 Chevy Task Force pickup, the axle widths vary by model and drivetrain, but the most commonly restored 1/2-ton trucks typically have a front axle width around 56 inches and a rear axle width around 60 inches. Heavier 3/4- and 1-ton models are wider overall, with front widths near 60 inches and rear widths in the mid-60s to upper-60s inches. Exact figures depend on the specific model year, options, and how the measurement is defined.
Understanding axle widths across 1956 Chevy Task Force trucks
What people usually want to know is the distance between the wheel mounting surfaces across the axle, i.e., the track width for both front and rear. The figures below reflect typical factory specifications for common configurations of the 1956 Chevy trucks, measured as the center-to-center distance between wheels on opposite sides.
Model-by-model expectations
Below are typical track widths by model and weight rating. Use these as a guideline for restoration work or parts fitting, but verify with the factory service manual or a parts catalog for your exact vehicle.
- 1/2-ton (3100) — Front track width: ~56 inches; Rear track width: ~60 inches
- 3/4-ton (3600) — Front track width: ~60 inches; Rear track width: ~66 inches
- 1-ton (3800) — Front track width: ~60–62 inches; Rear track width: ~66–68 inches
These figures are approximate and reflect common configurations from that era. Variations can occur due to production tolerances, optional equipment, or aftermarket changes.
How to verify the axle width on your specific truck
If you want to confirm the exact dimensions for your individual vehicle, follow these steps. They apply whether you’re restoring a project or fitting aftermarket components.
- Measure front width: With the vehicle on a level surface and the steering centered, measure from the center of the left front wheel hub to the center of the right front wheel hub. This is the front track width.
- Measure rear width: Do the same across the rear wheels, measuring from the center of the left rear wheel hub to the center of the right rear wheel hub. This is the rear track width.
- Note vehicle details: Record the exact model (3100/3600/3800), wheel size, and any factory options, as these can influence the width slightly.
- Consult primary sources: For the most precise data, check the original Chevrolet Shop Manual for the 1955–1959 Task Force trucks or the GM Parts Catalog corresponding to your build date.
If measurements are difficult due to rust, tires, or suspension components, you can also compare your truck to surviving factory reference images or seek guidance from classic Chevrolet truck clubs and archives.
Summary
In short, the axle width of a 1956 Chevy truck depends on the model: roughly 56 inches front and 60 inches rear for the 1/2-ton; about 60 inches front and 66 inches rear for 3/4-ton; and around 60–62 inches front with 66–68 inches rear for 1-ton configurations. Always verify against the exact vehicle’s manual or factory specifications for precise numbers.
