Bump Stop Puck 50dr Green 1/2in

The Bump Stop Puck 50dr Green 1/2in from ALLSTAR PERFORMANCE is a precision elastomer isolator designed to absorb shock and vibration in vehicle suspension systems. These pucks function as cushioning elements between chassis components and mounting hardware, protecting critical drivetrain parts from impact damage during acceleration, braking, and rough terrain operation. Whether you're building a high-performance race car, restoring a classic hot rod, or upgrading a street vehicle, bump stop pucks are essential for reducing NVH (noise, vibration, harshness) transmission to the frame and improving overall ride quality.

This bump stop features a 50-durometer green urethane compound that delivers the ideal balance between compliance and load-bearing capacity for most street and moderate-performance applications. The 2.1-inch outer diameter with 0.625-inch bore accommodates standard fastener sizes, while the 0.5-inch height provides controlled deflection without bottoming out under normal operating loads. Urethane's superior resilience compared to rubber ensures consistent damping over thousands of cycles, resisting oil degradation and ozone damage that compromises elastomer durability. The 50-durometer rating—measured on the Shore A hardness scale—offers moderate stiffness suitable for engine mounts, transmission isolators, and general chassis suspension applications.

Technicians, fabricators, and weekend enthusiasts benefit from stocking these versatile pucks for engine bay rebuilds, motor swap projects, and suspension geometry corrections. Installation is straightforward: position the puck between the mounting surface and bolt assembly, ensuring the bore aligns with fastener centerline, then torque to secure. The green color aids identification and visual inspection, making it easy to spot worn or compressed pucks during routine maintenance. This single puck is sold individually, allowing you to replace isolated components or order multiple units for complete suspension renewal on any project vehicle.
