PRODUCT OVERVIEW Adjust camber or caster 0.3 using the factory offset in the lower control arm bushings of many platforms. Place the grooved bolt in the forward arm's bushing to change caster or in the rearward arm's bushing to change camber. If both camber and caster change are needed, you must use 2 kits. Strutmasters uses a hex chromate free finish and offers a 700hr salt spray test for the best corrosion protection available.
