Pro-Ride Coil Springs

A pair of full-length, diesel-specific, progressive rate Pro-Ride coil springs are supplied to provide the correct lift height and smooth, predictable ride across various terrains.

Steering Correction

Important Notes

1. 6.4L gas models will require exhaust modification to clear the front driveshaft. 5.7L gas models may require exhaust modification as well. The vehicle can be driven without the front driveshaft to an exhaust shop for modifications to be made before reinstalling the driveshaft.
2. The carrier bearing drop is necessary for models equipped with two piece rear drive shaft.
3. Some vehicles may require rear driveshaft spacer kit 122007 to maintain adequate rear driveshaft engagement.
