SPC 1999-2006 Cadillac / Chevy / GMC Adjustable Upper Control Arms, Pair

Get your GM Truck or SUV’s front caster back in spec with these fixed offset upper control arms. Whether you lift your 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 your alignment in and get your driveability back.

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. Just swap these arms left to right and get -2° caster change if you need it.

These arms feature:

• Full forged construction for maximum strength.
• Booted and greasable ball joints.
• 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 (NVH).
