Belleville Washer Stack for WM269 Limit Chain

The Belleville Washer Stack for WM269 Limit Chain from WEHRS MACHINE is a precision suspension component engineered for racers and serious vehicle builders who demand exact control over suspension travel limits. These stacked Belleville washers function as a critical load-limiting interface in suspension restraint systems, preventing excessive chain deflection while maintaining consistent clamping force throughout the suspension's operating range. Whether you're building a race car, drag racer, or high-performance street machine, this component ensures repeatable suspension geometry and predictable limiting behavior under extreme conditions.

Each washer in this set measures 1.0 inch outer diameter with a 0.515 inch inner diameter and 0.043 inch thickness, manufactured from hardened steel in natural (uncoated) finish. The stacked configuration creates a spring-like assembly that compresses under load, absorbing shock impulses while limiting maximum deflection of the restraint chain. The Belleville design provides superior load distribution compared to flat washers, reducing stress concentration and extending component life in high-cycle applications. Stacking multiple washers allows fine-tuning of spring rate and travel limits—a critical advantage when dialing in suspension behavior for different track conditions or racing formats.

This set of 10 washers is ideal for builders installing or servicing WEHRS MACHINE suspension limiting chains on independent rear suspension systems, upper control arms, or specialty drag and circle-track chassis. Installation involves stacking the washers around the limiting chain anchor point, allowing precise adjustment of preload and maximum travel. The compact weight of 0.08 lbs per set keeps unsprung mass minimal—crucial for maintaining suspension response and chassis dynamics. Suspension tuners can layer these components to achieve exact stiffness values, making them essential for anyone serious about suspension repeatability and performance optimization.
