Washer Shims 1.350 x .006 500 Valve (10pk)

The Penske Racing Shocks Washer Shims 1.350 x .006 500 Valve (10pk) is a precision shock valve component designed for serious suspension tuning in high-performance racing applications. These steel washer shims are engineered to fine-tune damping characteristics by controlling oil bypass behavior through the shock valve stack, allowing teams to dial in exactly the compression and rebound rates their setup demands.

Each shim measures 1.350 inches in outer diameter with a precise .006-inch thickness, offering the subtle valve modifications that separate competitive advantage from baseline performance. The natural finish steel construction resists corrosion under typical racing conditions while maintaining the hardness required for repeated cycling under load. This 10-pack provides sufficient inventory for multiple shock builds, valve stack experiments, or replacement during seasonal maintenance—eliminating downtime when tuning mid-season or switching between track conditions.

Penske Shocks washer shims are essential for teams running custom-valved shock absorbers who need granular control over damping response. Whether adjusting for concrete ovals, road courses, or off-road terrain, these shims allow engineers to modify valve stiffness and flow characteristics without replacing entire valve assemblies. The consistent .006-inch thickness across the pack ensures repeatability—critical when establishing baseline setups before making intentional adjustments for track-specific tuning.

Shock valve stack design is fundamental to suspension performance. Proper shim selection directly influences how quickly oil flows through the valve in both compression and rebound phases, affecting ride height stability, chassis balance, and tire contact. Quality shim packs from established manufacturers like Penske ensure dimensional accuracy and material consistency that aftermarket alternatives often lack, justifying their use in competition environments where every adjustment counts.

Stock the right shim specifications for your suspension platform. This 10-pack delivers the quantity needed for professional valve work, whether you're building new shocks, refreshing worn components, or maintaining spare units for race weekend support.
