These precision-engineered valves are an excellent choice for cylinder head builds and performance upgrades.

Key Features:

• Forged from one-piece stainless steel 21-4N for maximum strength and durability
• Black nitride coating applied to the entire valve for superior wear resistance and heat dissipation
• Standard head diameter of 26.90mm with 5.96mm stem diameter
• Overall length of 105.09mm for precise fitment
• Triple groove design for use with standard valve keepers

Supertech valves are manufactured to exacting specifications and are trusted by racers and performance builders across drag racing, rally, road racing, and other motorsports disciplines. The black nitride treatment provides enhanced durability compared to chrome-coated alternatives, as it's applied to the entire valve rather than just the stem.
