Replace your stripped or corroded factory adjusters on GM's Lambda platform vehicles with SPC's rear camber and toe adjustment bolts. This pair of camber bolts can be used to replace camber or toe bolts on either side of the car. You will need 2 kits to replace all four positions. This kit provides the same adjustment range as the factory cam bolts. Need front camber adjustment? The Lambda platform can use SPC's EZ cams to add quick camber correction on the front suspension. SPC uses a hex chromate free finish and offers a 700hr salt spray test for the best corrosion protection available.

California Residents WARNING

Replace failed cross axis ball joints and frozen cam adjusters on the rear upper control arm of GM's popular lambda platform vehicles with SPC's cam bolt and xAxis kit.

California Residents WARNING

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 +2° 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 -2° caster change if you need it. Need to replace the OE adjusters? Consider SPC's p/n 86375 replacement cams, p/n 86325 replacement alignment pins and p/n 86320 alignment locking plates.

California Residents WARNING

These offset pin joints replace the upper pin joint on late model Dodge Trucks. They come in 1/2 degree increments and provide for independent wheel caster and/or camber changes up to 1-1/2 degrees. Use installation sleeve set 23780 in conjunction with ball joint press 72509 for quick removal and installation of the pin joints.
