Fabtech’s Uniball UCA 4" lift system for 2014–2018 GM K1500 pickups replaces stock upper control arms with tubular Uniball arms and uses factory coilover shocks with spacers to lift the front. Built with 4130 chromoly tubing and PTFE-lined uniballs, the system relocates the front differential, adds a 1/4" skid plate, and is intended to clear 33" tires while restoring suspension geometry for aggressive off-road use.
