This heavy duty cam-bolt kit was specifically designed for the extreme Raptor & F-150 user. Whether you are a energetic Raptor driver or abuse your F-150 in the fields and on the job site, you may have found that the OE bolts slip or that a single cam option does not hold alignment. This upgraded cam kit features two cams and bosses per bolt. The two cams will keep your bolt square and make adjustments easier while the new bolt and low friction finish achieve 25% more clamp load than the OE hardware. Some drilling is required to accomodate the second boss plate. This kit is sold per wheel and fits Raptors, non-Raptor F-150's and related SUVs. SPC uses a hex chromate free finish and offers a 700hr salt spray test for the best corrosion protection available.
