Bump Stop Puck 40dr Brown 3/4in Tall 14mm

The Bump Stop Puck 40dr Brown 3/4in Tall 14mm from ALLSTAR PERFORMANCE is a precision elastomer isolator engineered to limit suspension travel and prevent metal-to-metal contact in high-performance and off-road vehicles. Whether you're tuning a street suspension, building a competition rig, or upgrading a truck for rough terrain, this bump stop puck serves as a critical compliance component that protects your chassis and drivetrain from damage during extreme articulation or bottoming-out scenarios. Mechanics and suspension specialists rely on quality bump stops to extend the operational life of shocks, springs, and frame components while maintaining predictable handling characteristics across demanding driving conditions.

Built from 40-durometer brown elastomer material, the Bump Stop Puck 40dr Brown 3/4in Tall 14mm features a carefully engineered hardness rating that balances energy absorption with durability—softer than solid bumpers but firm enough to provide consistent bottoming resistance across temperature ranges and repeated impact cycles. The 3/4-inch height and 14mm bore diameter are precisely dimensioned to fit OEM and aftermarket shock mounting locations, while the brown polyurethane compound resists oil degradation, UV exposure, and ozone better than standard rubber alternatives. This durometer specification allows the puck to compress progressively under load, dissipating shock energy smoothly rather than creating harsh rebound spikes that can destabilize handling or cause component failure during trail driving or track work.

Technicians and fabricators installing this bump stop puck should verify bore diameter compatibility with your shock eyelet or mounting stud—the 14mm specification suits most modern coilover and air-suspension platforms. Installation requires sliding the puck over the shock rod or mounting pin and securing it with the appropriate retaining hardware; proper seating ensures the elastomer compresses uniformly under suspension load without lateral shifting or premature wear. This component is ideal for lifted trucks, rock crawlers, drag race suspensions, and any application where suspension geometry demands controlled travel limits and vibration isolation at the shock mounting point.
