Q: Are the included retainers compatible with stock valves?

A: Yes, these precision-ground retainers are designed to work seamlessly with the Raptor valvetrain, ensuring even seating and a straightforward installation process.

Q: Do I need to perform any special setup when installing these springs?

A: While these are a direct-fit upgrade, it is always recommended to check your installed height and ensure your valvetrain geometry is correct. Pairing these with billet rockers is highly recommended to maximize the efficiency and durability of your top-end build.

Q: How often should I inspect my valve springs?

A: In competitive karting, valve springs are high-stress components. We recommend inspecting them for signs of fatigue or loss of tension during your routine engine rebuilds to maintain peak performance and prevent potential engine failure.
