Dual Spring Retainers - 1.450/1.140/.745

The DEL WEST Dual Spring Retainers in 1.450/1.140/.745 dimensions represent a precision valve spring component engineered for high-performance engine builds. These lightweight titanium retainers are designed to manage dual-spring valve train configurations, offering the geometry and material composition necessary for aggressive valve spring rates common in modified and racing applications. The stepped outer diameter design (1.140 in / 0.745 in OD steps) ensures proper seating and load distribution across dual spring setups, critical for maintaining valve control at elevated RPM.

The 7-degree super lightweight construction reduces rotational mass on the valve train, minimizing parasitic losses and allowing faster valve acceleration. Titanium construction delivers strength-to-weight advantages over conventional steel retainers while resisting thermal cycling stress inherent in high-output engine environments. This set includes 16 retainers—sufficient for a complete eight-cylinder engine or partial application on larger displacement platforms. The precision dimensions ensure compatibility with matching spring and seat specifications, making these components essential for builders working with specific valve train geometries that demand exact engineering tolerances.

Users assembling dual-spring valve trains for performance engines, whether naturally aspirated competition builds or forced-induction platforms, require valve spring retainers engineered to handle increased spring pressures without deflection or failure. The stepped diameter configuration addresses the dimensional requirements of dual-spring stacks, where inner and outer springs demand different bearing surfaces. Engine builders, performance shops, and serious enthusiasts working on high-RPM platforms select these DEL WEST retainers for their proven reliability in demanding applications where valve control directly impacts engine longevity and peak performance output.
