Bump Stop Roller Skate Wheel 1in Tall 50dr

The Bump Stop Roller Skate Wheel 1in Tall 50dr is a precision-engineered suspension tuning component designed to provide controlled deceleration of the shock assembly during full compression. Professionals looking to buy this Allstar Performance puck understand that managing the final inches of suspension travel is critical for maintaining chassis stability and protecting expensive internal shock valving. By acting as a secondary, progressive spring, this urethane wheel prevents harsh metal-to-metal contact when the vehicle encounters significant bumps or heavy aerodynamic loads.

Technical specifications for this component highlight a 50 Durometer rating, which is visually identified by its green urethane construction. In automotive suspension terminology, the durometer indicates the hardness and energy absorption characteristics of the material. A 50dr rating offers a softer, more compliant engagement compared to higher-density pucks, making it an ideal choice for applications requiring a smoother transition into the bump stop. This specific density helps maintain the tire contact patch by absorbing energy rather than reflecting it back into the chassis.

Reviewing the physical dimensions, the Bump Stop Roller Skate Wheel 1in Tall 50dr features a 2-inch outer diameter and a 0.625-inch inner diameter, specifically sized to fit 5/8-inch shock shafts. The 1-inch height allows mechanics to stack multiple units or mix various durometers to create a custom, multi-stage compression rate. Unlike standard rubber stops, the high-quality urethane material used here is resistant to oils, chemicals, and thermal degradation, ensuring that the spring rate remains consistent throughout the duration of a race or a long-distance drive.

Whether you are fine-tuning a competitive dirt track car or optimizing a high-performance street build, these shock mount pucks are essential for sophisticated suspension geometry management. The precision-molded design ensures a square fit against the shock body or retainer, preventing binding during rapid suspension cycling. Incorporating these Allstar Performance components into your setup provides the technical edge needed to manage travel limits without sacrificing ride quality or mechanical longevity.
