Spirolock Retaining Ring 1.025 Stainless Steel

The Spirolock Retaining Ring 1.025 Stainless Steel is a precision snap ring engineered for high-performance shock absorber assemblies and spherical bearing applications in motorsports and performance automotive builds. Whether you're servicing Penske Racing Shocks on a dedicated track vehicle or rebuilding suspension geometry for maximum compliance, this retaining ring provides the mechanical restraint needed to keep critical bearing preload and damper internals secure under extreme compression and extension cycles. Built to OEM racing specifications, it's an essential wear item for anyone who demands reliability in chassis dynamics.

Machined from 300-series stainless steel, the Spirolock Retaining Ring features a snap-fit design that resists corrosion and maintains consistent spring tension across thousands of suspension articulation cycles. The 1.025-inch bore diameter matches OEM spherical bearing standards, ensuring precise fit without wobble or radial play—critical factors when shock damping curves and geometry must remain predictable lap after lap. Stainless steel construction eliminates rust degradation common in carbon steel rings, preserving ring elasticity and load retention even in wet or salt-exposure environments typical of road racing or off-road motorsports.

This ring is ideal for shock technicians, suspension builders, and performance enthusiasts restoring or upgrading Penske Racing Shock assemblies and compatible spherical bearing cartridges. Installation is straightforward—snap the ring into its groove on the bearing bore—but proper seating is critical to prevent component migration during high-load suspension events. Weighing just 0.04 pounds with minimal overall footprint, it integrates seamlessly into compact shock bodies without adding unsprung mass. For drag racing, autocross, road racing, or circle-track applications where suspension integrity directly impacts lap times and safety, having quality OEM-grade retaining rings on hand ensures minimal downtime between service intervals.
