Quicksilver® Cylinder Heads

 

 

 

Features

  • Better Than Original

    We made the castings thicker, improved the combustion chamber for better burn characteristics, and included premium springs and hardened seats on the intake and exhaust ports for our exclusive Black-X valves.

  • Black-X Valves

    Black‑X composite valves contribute to a 42% reduction in valve wear compared to traditional stainless steel valves with hardened seats, for longer engine life, especially in the presence of modern ethanol-blended fuels.

  • One-Year Limited Warranty

    The quality of Quicksilver cylinder heads is backed with a one-year limited warranty.
