Bilstein Splitter Washer

The Bilstein Splitter Washer is a precision-engineered bump stop component designed for use with Bilstein shock absorber systems in high-performance motorsports and suspension tuning applications. This splitter washer serves as a critical interface component that manages suspension travel and load distribution, making it essential for racers and enthusiasts who demand consistent, repeatable shock performance. Whether you're fine-tuning a drag car, road course racer, or street-performance vehicle, this washer helps optimize the shock's compression characteristics and overall suspension geometry.

Manufactured from aluminum in a natural finish, the Bilstein Splitter Washer features a 1.975-inch outer diameter (OD) and 0.575-inch inner diameter (ID), allowing it to fit precisely within Bilstein shock cartridges and suspension assemblies. The aluminum construction provides a lightweight yet durable solution that resists corrosion while maintaining dimensional stability under thermal and mechanical stress. Its compact 0.2-inch profile ensures seamless integration into tight suspension packaging without compromising shock responsiveness or travel range, making it ideal for both street and competition setups.

This component is particularly valuable for suspension builders, shock technicians, and motorsports competitors who customize Bilstein shock absorber configurations for specific vehicle dynamics and track conditions. Installation requires basic mechanical knowledge and compatibility with Bilstein shock systems—consult your shock tuning guide or suspension specialist to confirm proper placement and stacking order. Sold individually, this washer is often purchased as part of a complete shock rebuild kit or when customizing compression and rebound rates for optimized vehicle handling.
