03-06 350Z & G35 Manley Valvetrain Components

Manley Performance has been manufacturing the finest stainless steel valves for over 40 years. Manley valves have been the standard of the industry from their inception, a fact that still remains true as they shift their focus and resources to the Sport Compact Market. The Manley Stainless Race Valves feature chrome stems, hard tips, fully machined surfaces and swirl polishing under their heads. These valves are available in both stock and oversized, so whether your pushing the limits of your motor or just rebuilding with stock size components, Manley has the valve for you. Manley Performance is synonymous with winning and their products power some of the fastest cars around.

When upgrading your valves it is a must to also upgrade the valve springs and retainers. Manley's valve springs are wound using the cleanest alloy available and are also heat treated to allow for durability. They are specifically designed to be used in high revving applications and are made to take whatever you can throw at them.

Manley titanium retainers are made of rugged and certified, heat treated aerospace grade titanium. They are a must for any high performance engine revving past the stock limits. The light weight mass allows the motor to rev higher safely, but still keeps dangerous valve float in check. Manley has designed these with the highest quality standards and it shows in every aspect.
