SPC Performance 86321 GM Alignment Cam Lock Plates - Pair - Fits Select 2011-2022 Chevrolet/GMC

Fits select 2011-2022 Chevrolet Colorado, Silverado 2500/3500 HD, and GMC Canyon, Sierra 2500/3500 HD.

Ensure your alignment settings stay exactly where you set them with the SPC Performance 86321 GM Alignment Cam Lock Plates. Many technicians find that once the original equipment (OE) plastic retainers are removed from GM truck cams, the adjustment frequently slips. These lock plates provide a robust mechanical lock between the cam bolt and the guide pin, preventing movement under heavy loads or off-road use.

This kit is engineered for specific suspension geometry: it provides upper control arm adjustment for GM 2500 and 3500 HD trucks, and lower control arm adjustment for the Chevrolet Colorado and GMC Canyon. For a complete front-end refresh, these plates are designed to work with the OE cam or SPC replacement kit #86376, and can be paired with SPC #86326 heavy-duty alignment pins to replace worn factory hardware.

• Mechanical Stability: Provides a positive mechanical lock for the cam bolt to the guide pin to maintain alignment specs.
