Replace the factory torque-to-yield (TTY) rear camber bolts on GM's Epsilon II platform with these hex chromate free 700 hour salt spray tested cam bolts from SPC. GM's hardware TTY and needs to be replaced with every alignment. SPC's hardware can be re-torqued in future alignments, so you will only need to replace them once. This kit is sold per wheel and gives you the same adjustment as the factory cam, +-2.0deg for camber. California Residents WARNING
