Get a GM Truck or SUV’s front caster back in spec with these fixed offset upper control arms. Lift the rig 3” or lower it 1” the caster will be out of factory specifications. The OE adjusters do not provide enough change, so install SPC offset upper arms for 2° caster change and then use the OE cams to dial the alignment in and get your driveability back. This kit includes arms for both the right and left hand side.
- Full forged construction for maximum strength
- Booted and greasable ball joints that will last for the life of your truck.
- SPC’s xAxis™ technology with a twist. The xAxis sealed flex joints used in these arms provide a free pivot for droop and misalignment so that OE caster and camber adjustments will not bind the joint. These joints also have rubber isolation to retain OE levels for Noise, Vibration, and Harshness.
