AV&V™ Extreme Duty Replacement Valves (5/16 stem)
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 longer life. AV&V™ Extreme Duty valves also feature a 45° angle below the lock groove to facilitate valve seal installation.
