High Performance Valves
Large diameter valves are essential for improved air flow. Cosworth high performance intake valves are produced from high quality stainless steel for maximum durability.
Exhaust valves are machined from Inconel for high temperature (2400° F) reliability. Each valve features swirl polished back for improved air flow and dished face for additional weight reduction.
Cosworth high performance valves are compatible with Cosworth Ultra Race Valve Spring Kits.
Ultra Race Valve Spring Kits
Cosworth Ultra Race Valve Spring Kits are engineered for use in situations that require valve control in extreme conditions.
Each kit consists of dual valve springs with matched lightweight titanium retainers, keepers, and hardened steel spring seats.
Cosworth Ultra Race Valve Springs are wound from the highest quality chrome silicone steel with chamfered ends and are heat treated and stress relieved for long term reliability.
Ultra Race Valve Spring kits are compatible with Cosworth high performance valves.
High RPM Valve Springs
Cosworth High RPM Valve Springs are the result of countless hours of engineering, testing and validation ensuring the best possible spring for high performance applications. Cosworth High RPM Valve Springs are wound from the world’s finest Japanese Kobe steel and feature dual chamfered ends to reduce wear on seats and retainers.
Each spring has been engineered with increased seat pressure
along with higher lift capability for optimum performance potential and improved valve control. Single spring design allows easy installation with no machining required and is perfect for typical high performance use.
