Pair of Bump Spring Caps

The pair of bump spring caps from EIBACH represents a foundational upgrade for anyone maintaining or modifying a vehicle's suspension system. These protective components shield your coilover or bump stop springs from dirt, debris, and UV degradation—critical protection that extends the lifespan of expensive suspension hardware. Whether you're running a lowered setup, performance coilovers, or factory suspension with aftermarket spring rates, bump spring caps prevent premature wear and maintain consistent spring performance throughout the vehicle's service life.

EIBACH's bump spring caps are engineered from durable elastomer material designed to compress and rebound without cracking or losing shape under repeated suspension cycles. The compact design—measuring 4.05 by 7.7 inches—allows seamless installation onto standard spring perches and bump stops without interference with brake lines, strut housings, or chassis components. Their lightweight construction (0.105 lbs per pair) adds negligible unsprung weight while providing thermal insulation and acoustic dampening that reduces suspension noise and harshness transmitted to the cabin.

Bump spring caps benefit owners of modified vehicles—track enthusiasts, drift competitors, and daily-driven lowered builds—as well as mechanics refreshing aging suspension systems. Installation requires no special tools; simply slide the caps onto your existing springs or bump stops. These caps are compatible with most independent double-wishbone, MacPherson strut, and multi-link suspension architectures where spring perches are accessible. For anyone serious about suspension longevity and maintaining factory ride quality during aggressive driving, this pair delivers straightforward, proven protection at a modest investment.
