Description
Production tolerances on Twin Cam rocker covers can allow them to shift when being tightened. This can cause misalignment, which not only looks bad but can compromise the sealing surface. In high-lift cam engines that have had the rocker covers relieved, misaligned covers can also cause rocker interference unless even more material has been removed. For these reasons, we have developed alignment screws to ensure that rocker cover alignment is correct. This product offers an improvement in both form and function of Twin Cam rocker covers. The quality you expect from JIMS allows us to give a lifetime guarantee on these made in USA screws.
