This Cam Bolt Kit is a replacement kit for the OE adjusters. The OE bolts on Toyota trucks and SUVs are frequently "frozen" and do not allow for adjustment. Remove the frozen bolt assembly and replace it with an SPC cam kit to get up to +/- 1-1/2 degree camber and caster change. OE adjuster assemblies that are severely corroded may require SPCs press tool 40915 for removal, making the job quick and easy. Front Adjustment range: Cam./Cas. +/- 1.50 degree Installation time: .3 hr/side Req.: 1 per wheel
