Manley Performance Products Titanium Valves are designed to optimize engine performance, reduce valve train weight, and accommodate high-rpm applications.

Ideal for reducing valve train weight, these valves improve engine efficiency and overall performance. They are tailored for high-rpm and extended high-rpm applications, allowing for higher engine speeds and compatibility with aggressive camshaft profiles.

• One-piece forged construction with grain flow, ensuring durability and minimizing potential weak points compared to head-welded alternatives
• Meticulously machined in CNC turning centers and valve stem grinders to maintain exacting tolerances for optimal valve performance
• Finest titanium alloys used for both exhaust and exhaust valves, balancing mechanical properties, hardness, ductility, and fatigue strength at specific temperatures
• Stringent final inspection and strict quality control measures for quality, performance, reliability, and delivery within tight tolerances
