Fabtech 14-18 GM K1500 w/OE Alum. UCA 6in Lift System - Component Box 2

The Fabtech Motorsports FTS21139 Uniball Upper Control Arm is designed for severe duty use, replacing thin stock upper control arms to prevent flex and ball joint failure during aggressive off-road driving. It features a 1-inch inner diameter stainless American Uniball and a 4340 heat-treated Uniball pin that fits factory ball joint taper without spindle modification. This component also includes additional caster for greater alignment adjustability and increases wheel travel when used with Dirt Logic 2.5 Coilover Shocks. Constructed with materials found on Trophy Trucks, it boasts a welded gusset reinforcing the Uniball cup to chromoly arm tubes for exceptional strength, and 17-4 stainless misalignments allow Uniballs to travel without arm/spindle interference.
