Manufacturer Description

Up front the lift kit includes diesel-specific FOX 2.5 coil-over shocks, 4-link control arms with conversion brackets, forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, and brake line brackets. To optimize steering geometry once lifted, a forged drop pitman arm is used to minimize the steering angle and pair it with a heavy duty track bar drop bracket to keep them in phase through suspension travel while recentering the front axle. In the rear this kit utilizes a high-strength fabricated lift block, longer u-bolts, brake line brackets and a matching set of FOX Performance shocks.
