Bump Stop Puck 55dr Orange 1/2in Tall 14mm

The Allstar Performance Bump Stop Puck 55dr Orange 1/2in Tall 14mm is a precision suspension tuning component designed for performance vehicles and race cars that require controlled compliance between the chassis and drivetrain components. Bump stops are essential for maintaining predictable suspension geometry and preventing metal-to-metal contact during extreme suspension travel.

This compact elastomer puck isolates vibration and absorbs impact loads that would otherwise transfer directly through the frame and suspension mounts. It features a durable elastomer construction rated at 55 durometers on the Shore A scale, balancing cushioning compliance with load support. The 1/2-inch height and 14mm center bore accommodate standard mounting applications, while the orange color aids quick visual identification during assembly and inspection.

Mechanics and chassis builders favor Allstar bump stop pucks for rear-end housing mounts, transmission crossmember isolation, and suspension arm pivot applications where motor movement and axle travel must be controlled without metal contact. The elastomer material resists oil, grease, and fuel exposure, maintaining consistent performance across extended driving seasons without degradation or hardening.
