Super Lock Valve Spring Retainer - Steel

The COMP CAMS Super Lock Valve Spring Retainer in steel is engineered for high-revving performance engines where valve control and durability are non-negotiable. This precision component sits at the heart of your cylinder head, managing the critical interface between valve springs and the valvetrain. Whether you're building a track-focused small-block, restoring a classic muscle car, or upgrading an existing performance head, a quality valve spring retainer directly impacts engine stability, RPM capability, and longevity.

Constructed from chromoly steel with black oxide finish, this retainer features a 10-degree taper and dual-spring design compatibility with spring diameters ranging from 1.500 to 1.550 inches and outer diameter steps of 1.125 / 0.745 inches. The geometry of the 10-degree angle optimizes seating, reduces spring bind, and ensures consistent load transfer from dual springs to the valve stem. COMP CAMS' Super Lock design prevents spring migration and rotation under extreme valve acceleration, critical when pushing beyond 6,500 RPM where inertial forces can destabilize conventional retainers. The black oxide coating provides corrosion resistance and a professional appearance in any engine bay.

Mechanics and engine builders favor this retainer for applications demanding reliability at sustained high RPM—street performance builds, road racing, and competition engines benefit most. Installation requires precision valve spring compressor work and careful alignment; compatibility depends on your specific cylinder head, spring package, and stem diameter configuration. At just 0.07 lbs per unit, this compact component packs serious durability into a design that's proven across thousands of builds. Always verify spring dimensions and retainer bore specifications before purchase to ensure proper fit and function.
