The Speedmaster PCE269.1002 is a set of 10 degree chromoly valve locks (keepers) engineered for high-performance engine applications. These valve locks feature an 11/32" diameter with standard install height, manufactured from chromoly steel for superior strength and durability under extreme valve spring pressures. Ideal for racing engines and high-revving builds, these keepers provide the precise fitment and reliability demanded by serious engine builders and performance enthusiasts.
Chromoly construction delivers enhanced wear resistance and load-bearing capability compared to standard steel, critical for maintaining valve train integrity in modified or competition engines. The 10-degree angle geometry is designed to work with compatible valve stem designs, ensuring secure retention of the valve assembly. Use these keepers when rebuilding or upgrading cylinder heads, replacing worn locks, or assembling high-performance valvetrain components.
