Full-length, dual-rate coils provide precise 5" lift height with a smooth, predictable ride on and off-road.
Corrected Steering Geometry
A forged drop pitman arm and heavy-duty track bar relocation bracket keep steering angles in phase, maintain proper axle centering, and restore factory-like handling after lifting.
Rear Lift & Support
The rear is elevated with a heavy-duty fabricated lift block, extended u-bolts, brake line brackets, and a matched set of your selected performance shocks.
