Cup Bump Spring .625in Shaft

The Cup Bump Spring .625in Shaft by EIBACH is a precision bump stop cup assembly designed for suspension systems requiring controlled compression travel and load management. This universal component serves as an essential upgrade for vehicles needing enhanced bump protection, particularly in lifted trucks, performance suspensions, and off-road applications where extended suspension articulation demands reliable impact cushioning. The bump stop cup absorbs and dissipates energy during extreme compression events, protecting suspension geometry and extending component lifespan.

Engineered from aluminum and finished in durable black anodized coating, the Cup Bump Spring .625in Shaft delivers corrosion resistance and lightweight performance. The 0.625-inch shaft diameter provides precise fitment compatibility with standard suspension mounting points, while the 2-inch cup design optimizes deflection characteristics and load distribution across the bump stop surface. EIBACH's manufacturing expertise ensures consistent spring rates and progressive compression behavior, critical for maintaining suspension responsiveness during both normal driving and extreme compression cycles.

This universal bump stop cup assembly is ideal for enthusiasts upgrading suspension systems, off-road truck builders, and performance vehicle owners seeking improved handling and component protection. Installation pairs with existing coil spring systems where additional compression bottoming control is required. The black anodized aluminum construction resists road salt and moisture exposure, making it suitable for both street and trail environments. Verify shaft diameter compatibility with your suspension mounting hardware before purchase to ensure proper fitment and optimal performance integration.
