Bump Stop Blue 1.95in OD x .375in Tall 85A Duro

The Bump Stop Blue 1.95in OD x .375in Tall 85A Duro is a premium polyurethane suspension isolator designed to absorb shock loads and limit suspension travel in demanding automotive applications. This compact puck-style bump stop serves as a critical cushioning component between suspension arms and frame stops, preventing metal-to-metal contact that would otherwise transmit harsh impacts directly to the vehicle's chassis. Whether you're building a high-performance street machine, off-road rig, or race vehicle, this BILSTEIN-engineered component protects critical suspension geometry and extends the lifespan of steering and suspension systems under extreme conditions.

Constructed from 85A durometer polyurethane in a distinctive blue color, the Bump Stop Blue features a 1.95-inch outer diameter with a 0.375-inch height, offering precise fitment in OEM and aftermarket suspension applications. The 0.550-inch inner diameter accommodates standard mounting studs and allows for secure installation with minimal assembly complexity. The 85A durometer rating provides optimal elasticity—firm enough to resist permanent deformation under repeated heavy loads, yet compliant enough to absorb vibration and shock without transferring noise into the cabin. This material science approach ensures the bump stop maintains consistent performance across temperature variations and vehicle use cycles.

This bump stop benefits suspension builders, off-road enthusiasts, and performance mechanics who demand reliability and consistent feel from their suspension tuning. The compact dimensions and universal mounting interface make it compatible with a wide range of double-wishbone, independent, and trailing-arm suspension systems where frame-clearance bump stops are required. Installation is straightforward—simply position the puck between the suspension arm and frame stop, secure with appropriate fasteners through the center bore, and confirm adequate clearance during full compression cycles. Each unit ships individually, allowing builders to purchase exactly the quantity needed for their specific application.
