Rod End Components
Rod End Components — Hardware, Spacers, Clevises, Weld Cups & Accessories
Suspension and control linkages benefit from durable, proper-fitting components. Achieving the correct suspension geometry is critical for getting the most out of your race car. These are the products The Chassis Shop uses on our own cars for those critical connections — and we think it’s wise to only use the best available when building your project. You can always count on Pro-Werks to do it right.

Safety Washers — Zinc Plated, CNC Machined
Safety washers (also called rod end washers) are used with rod ends and heim joints to prevent the ball of the rod end from pulling through rod end body should the body fail — a critical safety component for any suspension or steering linkage. The generous radius undercut allows for maximum rod end misalignment angle. May also be used as spacers on each side of the rod end. Precision CNC machined mild steel, gold zinc-plated for corrosion resistance. Made in USA
