Bump Stop Puck 40dr Brown 1in Tall 14mm

The Bump Stop Puck 40dr Brown 1in Tall 14mm from Allstar Performance is a precision elastomer isolation component designed for suspension and shock-mounting applications in high-performance vehicles. This polyurethane puck is essential for racers, suspension tuners, and off-road enthusiasts who require reliable shock mount performance.

Manufactured from 40-durometer polyurethane, this puck absorbs vibration and impact loads while maintaining structural integrity under dynamic stress. The 40-durometer rating indicates a medium-hardness compound that effectively absorbs shock energy while resisting permanent deformation during repeated impact cycles. Standing 1 inch tall, this bump stop puck fits standard shock mounting configurations and serves as both a vibration damper and structural spacer.

Ideal for 14mm shock systems commonly found in circle-track racing, road course competition, and high-performance applications, the brown polyurethane formulation resists UV degradation and maintains performance across a wide temperature range. This ensures consistent behavior whether racing in summer heat or cold-weather conditions, making it a reliable choice for demanding drivetrain environments.
