Fabtech’s Uniball upper control arm lift system for 2019–2021 GM C/K1500 pickups combines heavy-duty 4130 chromoly tubing (.120" wall, 1.50" OD) with FK stainless PTFE-lined 1" uniball bearings for durability in rugged use. The Uniball arms improve on-road feel and longevity; rear lift uses 1.5" blocks and u-bolts. Installation notes include no driveshaft modification and a 2–3 hour install time, with cutting required.
