The Manley 11506-8 Race Steel Valve is a high-performance intake valve designed for serious racing applications. This valve is manufactured using Manley's proprietary race steel alloy, which provides superior strength, durability, and heat resistance compared to standard valves.
The valve features a full-length, spherical seat design that ensures positive sealing and reduces the risk of seat damage during high-RPM operation. The valve stem is made of stainless steel and is fitted with a titanium valve stem seal, which minimizes friction and provides excellent sealing.
The Manley 11506-8 Race Steel Valve also includes a sodium-filled, nickel-silicon valve head. This design evenly distributes heat away from the valve core, reducing the risk of thermal stress and promoting more consistent valve performance.
Additionally, the valve comes with a titanium retainers and lock nuts, which are lighter and stronger than standard components. This reduces rotating mass, allowing the engine to rev more freely and respond more quickly.
The Manley 11506-8 Race Steel Valve is available in various sizes to fit different engine applications. It is recommended for use in high-performance, racing engines where maximum power, durability, and reliability are required.
In summary, the Manley 11506-8 Race Steel Valve is a high-performance, race-proven intake valve made from Manley's proprietary race steel alloy. It features a full-length, spherical seat design, sodium-filled, nickel-silicon valve head, titanium retainers and lock nuts, and is available in various sizes to fit different engine applications. This valve is ideal for serious racing applications where maximum power, durability, and reliability are critical.
