Bump Stop Puck 40dr Brown 1/2in Tall 14mm

The ALLSTAR PERFORMANCE Bump Stop Puck 40dr Brown 1/2in Tall 14mm is a precision polyurethane shock mount designed to isolate vibration and absorb impact energy in suspension systems. This puck-style bump stop functions as a critical suspension component, preventing direct metal-to-metal contact during suspension compression and protecting both the shock absorber and mounting points from premature wear and damage.

At 0.5 inches tall with a 14mm shock mounting interface, this bump stop puck is engineered to fit OEM and aftermarket 14mm shock applications. The 40-durometer polyurethane compound provides a measured balance between deflection and load-bearing capacity—firm enough to maintain structural integrity under sustained lateral loads, yet compliant enough to absorb sharp transient impacts without transmitting shock through the chassis. The brown polyurethane composition resists UV degradation better than untinted formulations, extending service life in vehicles exposed to direct sunlight over extended periods.

This component is essential for suspension builders, off-road enthusiasts, and race teams seeking to reduce metal fatigue at shock mount points and improve ride quality by decoupling suspension articulation from chassis vibration. ALLSTAR PERFORMANCE bump stop pucks are commonly used in circle-track racing, street rod builds, and suspension upgrades where controlling impact harshness translates directly to driver comfort and component longevity.

Shock mount isolation is a proven engineering principle in both factory and performance suspension design. This puck-style isolator is sold individually, allowing builders to replace worn or deteriorated mounts or to upgrade existing suspension installations with higher-performance elastomer material.
