The 1.365 TI Valve Spring Retainer - 8 Degree from PAC Racing Springs is designed for high-performance engine builders and automotive enthusiasts who demand precision in their valve train components. This retainer is essential for maintaining optimal spring geometry and ensuring consistent load transfer from the camshaft to the valve stem, making it ideal for both naturally aspirated and street strip applications.
Constructed from titanium, this retainer offers significant weight savings, which helps reduce inertial load on the valve train. The 8-degree valve angle designation optimizes the interface with valve spring cups, preventing spring bind and surge under dynamic conditions. The retainer's 1.365-inch outer diameter ensures compatibility with modern dual-spring assemblies, while its precision manufacturing maintains tight tolerances to prevent valve float.
Engine builders utilizing PAC Racing Springs' complete valve train systems will find this retainer particularly beneficial for sustained high-RPM operations in road racing, autocross, or engine dyno applications. Proper installation requires attention to valve spring installed height and seat specifications to maximize performance and reliability.
