The SPC Performance cam lock plate solves the common problem of GM truck cams that will not hold once the plastic retainer is removed from the original equipment cam. It provides a mechanical lock for the cam bolt to the guide pin. Dial in the adjustment with the OE cam or SPC's replacement kit, then replace the nut-side cam with the lock plate to hold the setting. This kit is designed for GM 2500/3500/4500 HD trucks using upper arm adjustment and the 2015 and up Chevy Colorado using lower arm adjustment. Use with SPC 86326 HD GM alignment guide pins.
