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

The Bump Stop Red 1.95in OD x .375in Tall 85A Duro by BILSTEIN is a precision polyurethane shock mount isolator engineered to absorb compression loads and control suspension movement in high-performance vehicles and off-road applications. This elastomeric puck serves as a protective buffer between suspension components, reducing noise, vibration, and harshness while extending the service life of shocks and mounting hardware. Bump stops are essential when upgrading to aftermarket suspension systems or when factory mounts show wear.

Manufactured from durable 85A-durometer polyurethane, this compact isolator combines resilience with controlled flex to manage impact forces without bottoming out prematurely. The red color indicates the specific durometer rating, which is critical for matching suspension stiffness and vehicle weight distribution. At 1.95 inches outer diameter and 0.375 inches tall with a 0.550-inch inner diameter, the puck is designed to fit standard shock tower mounting points and suspension arms. The material resists oil, heat, and UV exposure, ensuring reliable performance across diverse driving conditions and seasonal temperature fluctuations.

Vehicle enthusiasts, suspension technicians, and off-road builders rely on BILSTEIN bump stops to maintain precise ride geometry and damping characteristics during aggressive terrain driving or track use. Installation requires minimal tools and fits directly into existing shock mounts without modification. Always verify durometer rating and dimensions against your specific vehicle platform—incorrect hardness can compromise suspension tuning and increase impact harshness. This single unit allows targeted replacement of worn isolators or upgrading of underperforming factory mounts.
