Get your GM truck or SUV's front camber or caster back in spec with these fixed offset upper control arms. Whether you lift your rig 3" or lower it 1" it is going to lose caster. The OE adjusters do not provide enough change, so install SPC offset arms for +2deg caster change and then use the OE cams to dial your alignment in and get your drivability back. These arms feature: *Fully forged contruction for maximum strength. *Booted and greasable ball joints that will last. *SPC's xAxis technology with a twist. The xAxis sealed flext joints used in these arms provide a free pivot for droop and misalignment that OE caster and camber adjustments will not bind the joint. These cross axis ball joints also have rubber isolation to retain OE bushing values for Noise, Vibration, and Harshness (NVH). Kit includes arms for both the right and left hand side. It can be used for lifted and lowered applications, if you drop your ride height more than 1" it will start to gain caster very quickly. These arms will still work for you, swap these arms left to right and get -2deg caster change if you need it. Need to replace the OE adjusters?
