What is the width of a 1955 Chevy rear end?
The stock rear track width for most 1955 Chevrolets is roughly 53.5 inches between the centers of the rear wheels; exact figures vary by model and brake setup. The overall rear-axle housing width follows a similar scale and can differ based on brake type and wheel size.
What the measurements mean
In classic Chevrolets, “width” can refer to two related measurements: the track width (distance between the centers of the rear wheels) and the axle housing width (end-to-end width of the differential housing). For restoration work and wheel swaps, the track width is typically the critical figure for clearance and fitment.
Stock width ranges
Below are the general ranges you can expect from typical 1955 Chevrolet bodies (Bel Air, 210, 150, Nomad) with stock rear axles. Note that small variations come from brake types (drums) and wheel sizes.
- Rear track width (wheel center to wheel center): approximately 53.5 inches (about 136 cm) on most stock 1955 Chevys.
- End-to-end axle housing width: typically within the low- to mid-50s inches, often close to 54 inches, with minor variation by model and brake setup.
In practice, exact measurements can vary by a fraction of an inch based on wheel offset, drum size, or if a factory option altered the rear geometry. For precise numbers, consult the original factory service manual for your exact model and year, or measure on the vehicle.
How to measure your rear-end width
To determine the width on your specific car, use a straightforward measurement approach that reflects how most restorers and builders plan fitment.
- Chock the car securely and remove the wheels to access the brake drums or hubs.
- Measure the distance between the centers of the rear wheel studs or hubs; this is the track width.
- Alternatively, measure between the outer surfaces of the brake drums or the inner surfaces of the rims if you’re using aftermarket wheels; ensure your measurement is taken from symmetrical points on each side.
- Record the measurement and compare it to the common stock range (around 53.5 inches) to determine if you have a standard rear end or a swapped/modified setup.
If you’re planning a swap (for example to a wider or narrower axle), consider how wheel offset, fender clearance, and driveline angles will interact with the new width. Consulting a professional or a supplier with a detailed specification sheet is recommended.
Common scenarios and swaps
Many owners swap the stock rear for modern or aftermarket axles to achieve different widths or gearing. The most frequent concerns are maintaining tire clearance, suspension travel, and driveline alignment. Always verify the width after any swap with a fresh measurement on the assembled car.
Summary: The rear-end width of a 1955 Chevy varies by model and options, but stock track width is typically around 53.5 inches between wheel centers, with axle housing width in the low-to-mid-50s inches. For exact figures, check the factory service manual for your exact model/year or measure the vehicle directly before any restoration or swap.

The stock width of a 1969 Camaro's rear end is approximately 60 inches or 60.25 inches from wheel mounting surface (WMS) to wheel mounting surface. Some sources also cite a width of around 59.5 inches for 1967-1970 models. The measurement can vary slightly depending on the source and what is being measured (e.g., drum to drum or WMS to WMS).
- Stock width: Approximately 60 inches (or 60.25 inches) WMS to WMS.
- Other reported width: Around 59.5 inches, specifically for the 1967-1970 models.
- Custom widths: Mini-tubbed cars or custom builds will have different, narrower widths.
