The Fabtech 4-inch Uniball upper control arm system for 2007–2018 GM K1500 trucks uses factory coilover shocks with steel spacers to retain ride quality while providing lift for 33-inch tires. Tubular 4130 chromoly arms with stainless PTFE uniballs and a 1/4-inch steel differential skid plate improve durability for aggressive offroad use, while rear performance shocks increase damping.
