Bump Stop Roller Skate Wheel 1in Tall 70dr

The Bump Stop Roller Skate Wheel 1in Tall 70dr from ALLSTAR PERFORMANCE is a precision urethane isolator designed for shock mounting and suspension component isolation in custom automotive builds. This yellow polyurethane puck serves as a vibration-dampening interface between frame-mounted components and shock towers, engine bay hardware, or chassis-critical assemblies where direct metal-to-metal contact would transmit unwanted vibration and noise into the cabin. Whether you're building a drag car, street rod, circle tracker, or street machine, bump stops like this are essential for preserving structural integrity while reducing harshness transmitted to the driver and reducing cumulative fatigue on bolt connections.

Manufactured from 70 durometer urethane, this roller skate wheel-style bump stop offers a balanced compromise between stiffness and compliance—firm enough to support load without bottoming out, yet compliant enough to absorb minor impacts and vibration harmonics. The 2-inch outer diameter and 0.625-inch inner diameter bore accept standard mounting hardware, while the 1-inch tall profile fits tight packaging scenarios where stack height is critical. Urethane at 70 durometer provides superior resistance to oil, fuel, and UV degradation compared to rubber alternatives, making it ideal for engine bay or underbody exposure where traditional elastomers fail prematurely.

Fabricators, engine builders, and suspension tuners rely on ALLSTAR PERFORMANCE bump stops for motor mounts, transmission isolators, frame-to-body isolation, and shock tower applications across circle track, drag, and street applications. Installation is straightforward: sandwich the puck between mounting surfaces using existing bolt holes, ensuring even clamping pressure to prevent material extrusion. One puck is supplied per order—calculate total quantity needed based on your isolation points before checkout to avoid project delays.
