Category Description
Isky Poly Locks replace OEM crimped rocker arm adjusting nuts and eliminate the bothersome re-adjustment procedures associated with the stock components, which are prone to come loose during competition. The alien set screw threads into the large hex-nut and securely shoulders against the top of the rocker stud to provide steadfast valve lash adjustment.
