Bump Rubber .500in Thick 2in OD x .50in ID Black

The RE SUSPENSION Bump Rubber .500in Thick 2in OD x .50in ID Black is a precision hydraulic bump stop engineered for performance suspension tuning and vehicle modification. Designed for enthusiasts and professional mechanics working on lifted trucks, lowered cars, and competition-level chassis setups, this bump rubber serves as a critical compliance element that controls suspension travel limits and absorbs the final-stage compression forces that occur during extreme suspension articulation. Whether you're fine-tuning a rock-crawling rig or dialing in a drag suspension, understanding bump stop selection is fundamental to achieving predictable, controlled suspension behavior across varying load conditions.

This bump rubber features a 0.5-inch wall thickness constructed from extra-hard 75 Durometer polyurethane foam, providing consistent compression resistance without the performance degradation seen in softer elastomers over repeated cycle use. The 2-inch outer diameter and 0.5-inch inner diameter profile allows integration into most OEM and aftermarket suspension architectures, positioning it as a drop-in solution for strut housings, coilover bodies, and custom fabricated bump stop mounts. The 75 Durometer rating delivers a firm, progressive compression curve—ideal for high-speed damping applications where you need controlled bottom-out resistance without harshness transfer to the chassis. Unlike rubber or urethane compounds that degrade under UV and thermal cycling, polyurethane foam maintains dimensional stability and damping characteristics across extended service intervals, making it the preferred choice for serious build work.

Mechanics and suspension specialists specify this bump rubber for applications requiring precise suspension compliance tuning—from off-road vehicles maximizing wheel travel to street applications preventing unintended frame contact during aggressive lowering. The compact 0.04 lb weight ensures minimal unsprung mass contribution while the compact dimensions (2.35 x 0.55 x 3.9 in) accommodate tight packaging environments common in modern coilover and air suspension retrofits. Installation is straightforward: slide the bump rubber onto the strut rod or compression stop shaft, ensuring proper seating within the housing to guarantee consistent preload and performance across the full suspension travel range. RE SUSPENSION's 5150 Series is OEM-trusted and race-proven, making this bump rubber a reliable specification component for any suspension modification demanding quality and repeatability.
