Spring 140mm Coil-Over 60mm ID

The Spring 140mm Coil-Over 60mm ID from EIBACH is a premium suspension component engineered for automotive enthusiasts and tuners seeking precision ride height adjustment and consistent spring rates across demanding driving conditions. This coil-over spring serves as the foundation for custom suspension builds, track setups, and performance street cars where factory geometry requires optimization. Whether you're building a dedicated autocross platform or refining a daily driver's dynamics, this 140mm length spring delivers the adjustability and predictable behavior that separates dialed-in vehicles from stock compromises.

With a 60mm inner diameter bore, this coil-over spring integrates seamlessly into most modern coil-over damper assemblies and aftermarket shock bodies designed to OEM or performance standards. The 140mm compressed length provides the stroke travel necessary for both lowered static ride heights and dynamic suspension compliance, allowing you to dial in corner weights and front-to-rear balance without sacrificing daily usability. EIBACH's manufacturing precision ensures consistent spring rates across the entire load range—critical when you're chasing lap times or maintaining stability during high-speed highway driving. The 3.16-pound component weight contributes to unsprung mass reduction, improving both acceleration response and wheel articulation during cornering events.

Mechanics and suspension fabricators benefit most from this spring when assembling complete coil-over kits or replacing worn springs in existing setups—a task that demands matched left-right rates to prevent handling imbalance and uneven tire wear patterns. Verify your coil-over damper's inner bore diameter and required spring length before purchase to ensure proper seating and full travel availability. This spring excels in independent double-wishbone and MacPherson strut applications where ride height adjustment combines with performance geometry for street, drift, and circuit use.
