Differentials Explained
Whether you are rebuilding a truck or restoring a daily driver, understanding differential types helps you pick the right reman unit.
The differential allows wheels to turn at different speeds in a corner while still receiving torque from the driveshaft.
- Open differentials are common on daily drivers; limited-slip adds traction.
- Ring and pinion ratio affects towing, fuel economy, and RPM at cruise.
- Verify axle code tags when ordering a complete assembly.
Contact our parts specialists if you need help matching a unit to your VIN.
