Manley Honda F20C/F22C Valve Spring and Retainer Kit (w/o Valve Locks)

The Manley Performance Valve Spring and Retainer Kit is built for Honda S2000 owners looking to push their F20C or F22C engine beyond stock limits. These kits are designed to handle the demands of aggressive aftermarket camshafts and high RPM operation, ensuring your valvetrain stays stable and controlled when you need it most. If you're rebuilding your top end or planning for serious performance, this kit offers a well-built solution for your S2000.

At the heart of this kit are chrome-silicon alloy springs, chosen for their exceptional fatigue resistance and high tensile strength. This means they can consistently control the valves even at extreme RPMs, up to 10,000 RPM according to Manley's specs. The kit also includes heat-treated, aerospace-grade titanium retainers that are CNC machined to very precise tolerances, ensuring a perfect fit and reducing overall weight in the valvetrain. While this specific part number (26150) does not include valve locks, it is designed to work with them, allowing you to use your existing or separately purchased locks.

This kit is a popular choice for S2000 owners who are upgrading their camshafts or aiming for higher performance levels. The included components are matched to work together, taking the guesswork out of selecting individual valvetrain parts. Remember to consult your service manual or a trusted mechanic for the correct installation procedures, as proper setup is crucial for achieving the intended performance and reliability from these components.
