Washer Shims 1.350 x .020 x .500 Valve (10pk)

The Penske Racing Shocks Washer Shims 1.350 x .020 x .500 Valve 10-pack (VW-135020-10) is a precision component engineered for high-performance shock valve assembly and tuning. These disc-style steel washers are critical fastening elements used in shock absorber construction, enabling engineers and technicians to calibrate valve stacks with exacting tolerances. Penske Shocks is recognized in motorsports and suspension engineering for manufacturing components that meet race-level precision standards, making this 10-pack a reliable supply for both single-build projects and ongoing maintenance cycles.

Each shim measures 1.350 inches in outer diameter with a 0.020-inch thickness and 0.500-inch inner bore, specifications that directly determine how shock valve stacks compress under suspension load. The steel material provides the durability and consistent spring characteristics required in dynamic racing environments where suspension tuning must remain stable across thousands of compression cycles. The precise thickness of 0.020 inches is critical—even minor variations in shim stack thickness can measurably affect shock damping curves, which is why OEM-quality tolerances matter. A 10-pack quantity provides sufficient inventory for prototype testing, multi-shock builds, or maintaining a competitive spare-parts supply.

This product is purpose-built for motorsports professionals, suspension engineers, shock technicians, and serious enthusiasts who assemble or tune race-spec shock absorbers. Whether you're building custom dampers for road racing, off-road competition, or suspension development, valve shim quality directly impacts the predictability and responsiveness of your shock performance. Penske Racing Shocks components are trusted across multiple racing disciplines where suspension calibration margins are measured in milliseconds and hundredths of an inch.

Shock valve shimming is a foundational suspension tuning technique that allows precise control of compression and rebound damping without replacing entire damper assemblies. Maintaining an organized inventory of precision shims in verified dimensions reduces downtime between race events and ensures valve stack configurations remain reproducible across multiple builds.
