Bump Rubber Cup .625in

The RE SUSPENSION Bump Rubber Cup .625in is a precision suspension component engineered to manage suspension travel and absorb impact loads in high-performance vehicle applications. This 3-inch cup-style bump stop delivers controlled compression damping when suspension reaches its maximum travel limits, protecting critical drivetrain and chassis components from hard bottoming. The aluminum construction with natural anodized finish provides a lightweight yet corrosion-resistant solution suited for off-road, track, and street-modified vehicles where suspension geometry demands precise tuning.

The .625-inch diameter bore and long base design accommodate standard suspension mounting configurations while maintaining consistent support geometry throughout the stroke. The 3-inch cup length allows adequate compression deflection without excessive preload on the suspension spring, a critical balance for maintaining ride frequency and preventing premature wear. Aluminum's inherent stiffness-to-weight ratio means this bump stop resists permanent deformation under repeated hard compressions while keeping unsprung mass to a minimum—directly improving suspension responsiveness and tire contact patch consistency over rough terrain or track transitions.

Builders and enthusiasts rely on RE SUSPENSION bump stops when tuning lifted trucks, trail-rated SUVs, or competition vehicles where maximum suspension articulation meets precision impact management. Whether dialing in a rock-crawling suspension, setting up a performance off-road platform, or fine-tuning a track-focused coilover system, this component provides the compliance needed to absorb shock loads without transmitting destructive impulses to the frame. The natural anodized aluminum finish withstands weathering and corrosion from mud, water, and salt exposure common in off-road environments.
