Replace the factory torque-to-yield (TTY) rear camber and toe bolts on GM's Epsilon II platform with these hex chromate free 700 salt spray tested cam bolts from SPC. GM's hardware is TTY and needs to be replaced with every alignment. SPC's hardware canbe retorqued in future alignments, so you will only need to replace them once. This kit is sold per wheel and gives you the same adjustment range as the factory cam, +-2.0deg for camber or toe. You may find that the factory toe bolt (which is not TTY on hyperstrut equipped models) is hard to reach. Use SPC's D-Bolt socket, p/n 45938 to make the job easy. California Residents WARNING
