Washer Shims 1.200 x .006 x .500 Valve (10pk)

The Washer Shims 1.200 x .006 x .500 Valve (10pk) by Penske Racing Shocks represent precision valve shim stock engineered for high-performance suspension tuning and engine valvetrain work. These critical components are essential for anyone building or modifying racing suspensions, performance shocks, or working with adjustable valve systems on competition engines. Whether you're fine-tuning damping characteristics on a track-focused build or dialing in valve clearances on a high-revving engine, quality shims directly impact performance consistency and reliability under extreme conditions.

Manufactured to Penske Racing's exacting tolerances, these washer shims feature a 1.200-inch outer diameter with a precisely controlled .006-inch thickness and .500-inch bore specification. The .006-inch thickness delivers micro-adjustments crucial for suspension valving or valve lash settings, allowing technicians to fine-tune hydraulic flow rates or mechanical clearances in increments that compound across multiple shims. Penske's shim stock maintains consistent hardness and flatness across the 10-pack, ensuring uniform performance whether stacked in shock absorber stacks or installed in cylinder head valve assemblies on performance builds.

Professional engine builders and suspension technicians rely on Penske Racing shims for factory-level precision in both OEM and custom applications. The 10-pack quantity supports multiple repairs, prototype builds, or staged tuning sessions without excessive inventory costs. Compatibility spans various Penske shock models and performance valvetrain applications; always verify bore diameter and thickness requirements against your specific shock stack or valve clearance specifications before installation to ensure proper fit and optimal damping behavior or mechanical function.
