The SPC GM alignment cam lock plate kit is engineered to secure cam bolt adjustment on GM 2500/3500/4500 HD trucks (upper arm) and 2015-up Chevy Colorado (lower arm). It provides a mechanical lock to hold changes after dialing in alignment and works with OE cams or SPC’s replacement kit. Finished with a tough hex-chrome-free coating, the kit is sold as a pair and is intended to improve adjustment retention.
