Maintain proper valve train performance with the Genuine Subaru Valve Spring Retainer Keeper (Part Number 13210AA020 / PT040299). This OEM valve collet securely locks the valve spring retainer to the valve stem, ensuring proper valve spring tension, alignment, and reliable engine operation.

Commonly known as a valve keeper, valve lock, or collet, this small but critical component plays a major role in maintaining proper valve control during normal operation and high-RPM conditions. A worn, damaged, or improperly fitted keeper can affect valvetrain reliability, making replacement important during cylinder head rebuilds, valve jobs, engine refreshes, and performance upgrades.

Manufactured to Subaru factory specifications, the 13210AA020 valve keeper delivers the precise fit, durability, and reliability expected from an OEM engine component.
