1.475 Pacaloy Valve Spring Retainers - 10 Dg

The PAC Racing Springs 1.475 Pacaloy Valve Spring Retainers in a 10-degree configuration are precision-engineered components designed for high-RPM engine applications where valve control and reliability are essential. These retainers are ideal for engine builders, racing teams, and performance enthusiasts who require robust solutions for their high-output naturally aspirated, supercharged, or turbocharged engines.

Constructed from Pacaloy steel, these retainers provide the strength and dimensional stability necessary to withstand demanding racing and performance engine builds. The 1.475-inch outside diameter features stepped geometry (1.110 in / 0.710 in OD steps) that accommodates dual-spring configurations, allowing for precise valve-spring preload management and harmonics control at elevated RPM. The 10-degree angle ensures proper seating with similarly angled valve spring seats, preventing rotational slippage during operation.

This set of 16 retainers provides complete coverage for a V-8 engine or partial coverage for specialized builds. PAC Racing Springs manufactures these components to tight tolerances, critical for maintaining consistent valve-train geometry across all cylinders and preventing premature wear or spring-seat damage. These retainers are a vital choice for anyone looking to optimize valve-spring compression and control in high-performance applications.
