1.365 TI Valve Spring Retainer - 8 Degree

The 1.365 TI Valve Spring Retainer - 8 Degree from PAC Racing Springs is engineered for high-performance engine builders and serious enthusiasts pushing aggressive valve train profiles. This precision component sits atop your valve spring assembly, controlling spring geometry and ensuring consistent load transfer from the camshaft to the valve stem. Whether you're building a naturally aspirated road course engine or preparing a street strip vehicle, a quality valve spring retainer is non-negotiable for reliability and repeatability at elevated RPM.

The 8-degree valve angle designation on this titanium retainer refers to the seat geometry that interfaces with your valve spring cups, optimizing spring bind and preventing unwanted spring surge under dynamic loading. Titanium construction delivers critical weight savings—only 0.03 pounds per retainer—which directly reduces inertial load on your valve train and allows higher safe RPM limits without sacrificing durability. The 1.365-inch OD specification ensures compatibility with modern dual-spring assemblies common in contemporary performance builds, while the precision manufacturing maintains tight tolerances that prevent spring binding and valve float.

This retainer suits engine builders working with PAC Racing Springs' complete valve train systems, particularly those targeting sustained high-RPM operation in road racing, autocross, or engine dyno applications. Installation requires proper valve spring installed height and seat-to-retainer clearance verification—critical steps that separate a reliable build from a costly failure. Compatibility depends on your specific valve spring cup diameter and camshaft lift profile, so confirm fit with your spring supplier or engine blueprint before purchase. PAC Racing Springs' reputation for precision manufacturing makes this retainer a trusted choice among professional builders and dedicated enthusiasts alike.
