Bump Stop Washer 14mm x 50mm 3mm Thick

The Bump Stop Washer 14mm x 50mm 3mm Thick is an essential suspension component engineered to limit suspension travel and prevent metal-to-metal contact in your vehicle's damping system. Built by BILSTEIN—a trusted name in OEM and performance suspension for over 70 years—this precision washer serves as a critical interface between the bump stop assembly and suspension tower, protecting both your shock absorber and chassis from catastrophic impact damage during extreme compression or off-road conditions. Whether you're restoring factory suspension geometry or upgrading a modified vehicle, this washer ensures your bump stop system functions as designed.

At 14mm bore diameter and 50mm outer diameter with a 3mm thickness, this washer distributes load evenly across the bump stop mounting surface, reducing stress concentration and extending component life under repeated compression cycles. The precision tolerance and rigid construction prevent washer deformation, which is critical to maintaining consistent bump stop preload and ride height—factors that directly affect suspension response, tire wear patterns, and handling balance. The compact 0.04 lbs weight confirms this is a genuine serviceable part rather than a cheap replacement, meaning it will not introduce deflection or compliance into your damping circuit.

This washer is essential for mechanics and enthusiasts rebuilding complete shock absorber assemblies, performing full-suspension swaps, or addressing worn OEM components that have caused ride height loss or unusual suspension noise. BILSTEIN OEM-equivalent parts are compatible with most vehicles that originally shipped with BILSTEIN dampers or similar German-engineered suspension systems. Always inspect the mating surfaces of the shock tower and damper body for corrosion or damage before installation, and torque the assembly fastener to manufacturer specification to ensure the washer maintains its load-bearing function throughout the service life of your vehicle.
