Product Details

This 8" Superlift'suspension system is built around massive 9-leaf full height front leaf . The leaf springs multi-leaf design provides a great ride while maintaining heavy-duty nature of the Super Duty. By making the springs out of 9 leafs SuperLift is able to keep the spring arch low which greatly improves the ride. The leafs have durable Poly spring bushings and Teflon inserts between each leaf to ensure a quiet and smooth ride. In addition, when the springs get loaded down, all of the leafs engage in a progressive nature and hold up to the added weight without sagging.

To make the steering function as well as the springs, a dropped pitman arm and track bar relocation bracket are included. Bump stop relocation brackets keep the suspension from compressing too far. Add in the Nitro shocks and this Superlift 8" kit offers one of the smoothest, controlled rides available for your Super Duty!
