How long are Chevy leaf springs?
There isn’t a single universal length for Chevy leaf springs. The length varies by model, year, and axle configuration. In practice, rear leaf packs on Chevy full‑size pickups are commonly in the 60–66 inch eye-to-eye range, with shorter or longer examples on older or smaller models.
Why the length varies
Leaf springs are designed to fit specific wheelbases and suspension setups. The same Chevrolet lineup can use different spring packs depending on payload, trim, and whether the vehicle is two‑wheel drive or four‑wheel drive. As a result, the actual length depends on the vehicle’s design and mounting points.
Common factors that influence length include:
- Vehicle model and year
- Wheelbase and rear axle mounting points
- Payload rating and whether the setup uses a single- or multi-leaf pack
- Factory vs aftermarket replacements
In all cases, the correct length must match the specific trim and drivetrain of the vehicle. When replacing springs, confirm the eye-to-eye length with GM’s factory manuals or a trusted parts catalog.
How to determine the exact length on your Chevy
To determine or verify the precise leaf-spring length for your Chevy, you can measure the spring directly or check the factory specs. The steps below walk you through a simple measurement and verification process.
- Ensure the vehicle is safely supported and the rear wheels are removed to access the leaf springs.
- Identify the front and rear eyes (the ends that bolt to the frame and axle). The length is typically defined as the eye-to-eye distance when the spring is unloaded.
- Use a tape measure to measure from the center of the front eye pin to the center of the rear eye pin along a straight line, along the plane of the spring.
- Measure on the unloaded spring in its natural free length; do not measure while the spring is flexed under load.
- Record the measurement and compare it to factory specs in the owner's manual, service manual, or a GM parts catalog for your exact year and model.
- If you are replacing, order the spring with the correct eye-to-eye length for your wheelbase and mounting hardware.
Measuring this way ensures you order the correct length and avoids fitment issues with brackets, shackles, and mounting pins.
Typical length ranges by Chevy vehicle family
These ranges reflect common configurations reported by manufacturers and aftermarket catalogs. Always verify exact numbers for your year and trim since variations exist across generations.
- Modern full-size pickups (Chevy Silverado/Sierra): roughly 60–66 inches eye-to-eye for the rear spring pack.
- Classic C/K trucks and some heavy-duty layouts (1960s–1990s): a broad range, commonly around 52–64 inches depending on wheelbase and payload setup.
- Smaller Chevy models (S-10, Blazer/Mid-size SUVs of the era): typically shorter packs, roughly 50–60 inches.
For definitive figures, consult the service manual for your exact year and model or contact a GM parts specialist with your VIN.
Summary
There is no single length for Chevy leaf springs. Length varies by model, year, wheelbase and payload. Most rear leaf-spring packs on Chevy pickups sit in the 60–66 inch range, with shorter lengths seen on older or smaller models. To obtain an exact measurement, measure the eye-to-eye length of the unloaded spring or verify the specification from GM’s manuals or a trusted parts catalog.
