Bump Stop Puck 40dr Brown 1in

The Bump Stop Puck 40dr Brown 1in from ALLSTAR PERFORMANCE is an essential suspension tuning component designed for serious vehicle builders and race mechanics who demand precise suspension geometry control. This compact elastomer insert is engineered to regulate suspension bump travel, preventing excessive compression that can compromise chassis stability during aggressive cornering, hard acceleration, or track driving. Whether you're dialing in a competition suspension setup or fine-tuning a high-performance street machine, the bump stop puck provides repeatable, controlled suspension behavior across a wide range of driving conditions.

This 1-inch bump stop puck features a 40-durometer rating, indicating a medium-firm elastomer compound that balances compliance with progressive load resistance—critical for maintaining consistent suspension feel throughout the stroke. The brown polyurethane material provides excellent temperature stability and resistance to hydraulic fluid, ensuring long service life without degradation across seasonal temperature swings common to both street and competition environments. At just 0.17 lbs with compact dimensions of 4 x 1.15 x 7.05 inches, the bump stop puck integrates seamlessly into OEM and aftermarket suspension systems, occupying minimal chassis space while delivering measurable suspension control improvements and preventing metal-to-metal contact during extreme compression events.

Mechanics and suspension specialists rely on ALLSTAR PERFORMANCE bump stop pucks for custom coilover setups, lowered street applications, and competition vehicles where suspension tuning precision directly impacts handling performance and component longevity. The 40-durometer rating suits most street and street-strip applications, offering a middle-ground compliance that works across varying road surfaces and load conditions without harshness or excessive bottoming. Installation is straightforward—mount the puck between the suspension spring perch and the shock body or coilover sleeve—making it an ideal retrofit component for suspension upgrades. Consult your suspension system specifications to confirm bore diameter and mounting configuration compatibility before installation.
