Bump Stop Puck 40dr Brown 3/4in

The ALLSTAR PERFORMANCE Bump Stop Puck 40dr Brown 3/4in is a precision urethane shock mount designed to isolate vibration and absorb impact energy in suspension and chassis mounting applications. Built from 40-durometer urethane, this puck delivers controlled compliance that reduces transmitted shock while maintaining structural integrity under load—essential for racing, off-road, and high-performance automotive builds where component protection directly impacts longevity and handling.

Specifications are matched to demanding vehicle dynamics. The 0.75-inch height, 2.1-inch outer diameter, and 0.625-inch inner diameter bore create a compact mounting interface suitable for engine cradles, motor mounts, frame isolation, and suspension geometry correction. The 40-durometer rating—a mid-range hardness in the urethane spectrum—strikes the balance between deflection and load support, absorbing road-induced vibration while resisting permanent deformation under sustained weight. Brown urethane formulation indicates a standard motorsports compound engineered for consistent performance across typical operating temperatures.

This bump stop puck serves racers, fabricators, and performance enthusiasts building custom suspension systems or engine installations where OEM mounts fall short. Common applications include motorsports crash testing, off-road suspension tuning, engine bay isolation, and chassis setup optimization. Sold individually, each puck can be integrated into multi-point mounting schemes or used as a direct OEM replacement where durometer and geometry match the original specification.

ALLSTAR PERFORMANCE bump stop pucks are foundational components in the motorsports supply chain, trusted by fabricators and teams where precision mounting geometry and vibration isolation cannot be compromised. This particular configuration—40-durometer, brown, 3/4-inch tall—is a versatile platform component stocked by serious racing shops and performance builders.
