Installation Notes

Verify spring dimensions, leaf count, arch length, and end-eye style before ordering. Confirm rear axle orientation and compare the existing spring’s measurements to the listed 25.125-inch and 30.625-inch lengths, 3-inch width, and 5.25-inch arch length. Bushings are included, while mounting hardware is not listed as included. Because fitment data is not provided, match this assembly to the original suspension configuration on the vehicle before installation.
