Supertech Performance Titanium Valve Retainer

Supertech Performance titanium valve spring retainers (also called valve spring retainer caps or titanium valvetrain retainers) cut valvetrain mass and help hold spring pressure at high RPM. They are a common upgrade for performance and racing engines. Lower reciprocating weight helps the valvetrain follow the cam profile more accurately and helps prevent valve float.

Key Features:

• Titanium construction: CNC machined from high-strength, aerospace-certified titanium alloy. Supertech lists 6AL4V grade titanium for its retainers.
• Reduced mass: Gives significant weight savings over steel retainers, so the valvetrain can rev higher and respond faster.
• Precision finish: Machined to tight tolerances for a secure fit and long-term durability.
• Valve float resistance: Lighter retainers work with higher-rate performance springs to help protect the engine at high RPM.
• Matched valvetrain components: Designed to be paired with Supertech valve springs and valve locks.

Titanium retainers give a good balance of strength and low weight for street, track and race builds. Titanium retainers can wear over time, so check them regularly, especially on high-mileage engines. Select the correct child item for your engine application.
