7in Coil Over Spring 2.5in ID

The EIBACH 7-inch coil over spring with a 2.5-inch inner diameter is engineered for builders and mechanics focused on independent suspension tuning for street, track, and off-road applications. This coil spring is designed to provide the necessary compression and extension rates required when upgrading to aftermarket coil-over shock absorber systems, particularly in lifted trucks and performance chassis builds.

Manufactured to strict load-rate tolerances, EIBACH springs ensure predictable spring rates and consistent performance across thermal cycles and extended duty. The 2.5-inch inner diameter accommodates most modern coil-over shock bodies, while the 7-inch length integrates seamlessly with mid-travel and long-travel suspension architectures. The linear rate characteristics of this spring enable precise body roll control and load transfer tuning, essential when paired with adjustable dampers.

This spring is particularly beneficial for mechanics and suspension builders upgrading independent or semi-independent rear suspension systems. It is ideal for lifted trucks, SUVs, and performance cars, providing a solid foundation for suspension geometry optimization. Proper installation requires matching the spring rate to the total vehicle weight to ensure optimal performance.
