Retainers

Upgrade your valvetrain with precision-engineered retainers designed to handle the stress of high-RPM and high-boost applications. Retainers work hand-in-hand with valve springs to keep your valvetrain stable, prevent float, and maximize engine performance.

At SBX Performance, we offer retainers in titanium, steel, and other high-strength alloys to suit everything from daily drivers to track builds. Lighter retainers reduce valvetrain mass, improving throttle response and allowing for higher rev limits without compromising durability.

Whether you’re pairing them with upgraded dual valve springs, prepping for aggressive cam profiles, or chasing reliability under forced induction, our retainers deliver the strength and precision you need. Combine them with springs, seats, and keepers for a complete performance package.
