Description
Rocker arm nuts are critical fastening points in any valvetrain—improper retention leads to catastrophic engine failure. Comp Cams' Magnum Polylocks eliminate the need for separate locking mechanisms, delivering secure, maintenance-free fastening with a single installation step. If you're building or rebuilding a serious engine, these are non-negotiable.
The polylock design uses a nylon insert that grips the bolt threads under tension, preventing loosening from vibration and thermal cycling without requiring lock washers or safety wire. This is industry-standard hardware for high-RPM applications where reliability isn't optional.
