Description

Spring Retainer Set

Upgrade your valve train with Manley Performance Titanium Retainers and other lightweight titanium options designed specifically for high-revving engines. Machined from aerospace-grade heat-treated 6AL-4V titanium, these retainers dramatically reduce valvetrain mass for quicker rev-up, improved valve control and enhanced overall responsiveness. The reduced weight helps your engine hold spring pressure at high RPM, minimizing float and unlocking more performance potential in race or aggressive street applications. Lightweight, strong, and precision-built for serious performance.
