Product Details

COMP Cams Hardened Steel Single Groove Street Locks are valve spring retainer locks (also called valve keepers or valve retainer keepers). They secure the valve spring retainer to the valve stem in street performance engines.

Key Features:

  • Hardened steel construction for strength and durability in street use
  • Single groove design that matches single-groove valve stems
  • 7 degree taper for a positive, secure fit between the retainer and the valve stem
  • Made by COMP Cams, a respected name in performance valvetrain components

These locks suit street performance and general engine rebuild applications. They help keep the valvetrain reliable and consistent. Several variants are offered, so pick the one that matches your valve stem and retainer.
