Dual Spring Retainers – 1.500/1.140/.745 RX-DW515-16

Description

Dual spring retainers are critical for maintaining valve train integrity under high RPM and aggressive lift profiles. These titanium retainers reduce rotational mass while providing the rigidity needed to prevent spring surge and valve float in extreme applications. Whether you’re building a naturally aspirated high-revving engine or a forced induction platform, precision retainers are non-negotiable for reliability.

The RX-DW515-16 features a 7-degree seat angle geometry designed to work with dual spring configurations, offering the step diameters (1.140″ and 0.745″ OD) required for compatibility with a wide range of valve spring packages. With titanium construction and CNC precision, this set of 16 delivers the durability and concentricity your engine demands.
