Installation Notes and Tips

Verify leaf spring dimensions, axle tube shape, thread diameter, inside length, and inside width before ordering. Confirm round-bend application details and match the vehicle position exactly, since this part is listed for both front and rear use depending on the vehicle. For best results, inspect the leaf spring pack, axle seat, and related hardware for wear before installation.
