Cup Bump Spring .500in Shaft

The Cup Bump Spring .500in Shaft is a precision bump stop component engineered for suspension systems requiring controlled compression and rebound limiting. Manufactured by Eibach, a trusted leader in suspension technology, this universal pair delivers reliable performance across a wide range of vehicles and suspension configurations. Bump stops protect your suspension geometry by preventing metal-to-metal contact during extreme compression, extending component lifespan and maintaining ride quality under demanding conditions.

This cup-style bump stop features a 0.500-inch shaft diameter and a 2-inch cup diameter, constructed from black anodized aluminum for corrosion resistance and durability in harsh environments. The anodized finish protects against oxidation while maintaining a clean, professional appearance. The elastomer spring element absorbs impact energy progressively, preventing abrupt suspension lockup that could transmit harsh jolts through the chassis and degrade ride comfort. Eibach's engineering ensures consistent performance across temperature variations and extended service intervals.

Off-road enthusiasts, motorsport competitors, and vehicle owners running lowered or modified suspension systems will benefit most from this durable bump stop pair. The universal design accommodates both OEM replacement applications and aftermarket suspension setups, including lifted trucks, performance cars, and rally vehicles. Installation is straightforward—the 0.500-inch shaft fits standard suspension mounting locations, and the 2-inch cup dimensions interface with most coilover and shock tower designs. Always verify shaft and cup dimensions against your vehicle's specifications before purchase to ensure proper fit and function.
