Designed to maintain factory alignment specs on vehicles with 1.5"-3" lift kits.

1" I.D. uniballs feature a heat-treated stainless-steel ball & heat-treated stainless-steel race for maximum corrosion resistance and component longevity. These uniballs also feature a military grade PTFE woven fabric liner that helps prevent noise and reduce maintenance.

CNC tapered spindle adapters convert the factory ball joint to a 1" uniball for easy installation.

Custom profile upper and lower hi-misalignment spacers are machined from 17-4 stainless-steel to maximize strength and wheel travel.

Urethane bushings reduce deflection compared to stock rubber bushings.

4130 chromoly tubular upper control arms are 100% bolt on.

Control arm pivots include zerk fittings to grease the bushings and inner sleeves without disassembly.

3 stage powder coat process includes a durable clear coat to provide a long-lasting finish.

Complete Grade 8 hardware kit is included.

Hand crafted in the U.S.A.
