AV&V Extreme Duty Replacement valves



These superb valves are one piece forged from a racing grade stainless steel alloy. Our liquid nitriding process creates a valve that is smoother and stronger than traditional O.E.M. or replacement valves.

The stems are centerless grinded to a micro finish for a longer life.

AV&V Extreme Duty valves also feature a 45o angle below the lock groove to facilitate the valve seal installation.
