Spring 2.5in ID Tender Linear

The EIBACH Spring 2.5in ID Tender Linear is a precision-engineered suspension component designed for vehicle builders and mechanics who demand predictable, repeatable spring performance. This linear-rate helper spring serves as a secondary spring system that manages load transfer and suspension geometry under dynamic driving conditions. It is particularly useful for those fabricating custom suspension setups or restoring classic cars.

EIBACH's linear spring design delivers a constant, predictable rate throughout its entire travel range, eliminating the progressive-rate inconsistencies that can cause unpredictable vehicle behavior during acceleration, braking, and cornering. With a 2.5-inch inner diameter specification, this tender spring integrates seamlessly with dual-spring or coilover setups where a secondary rate is required to manage suspension compliance at both low and high speeds.

This component is ideal for fabricators working on various suspension systems, ensuring stability and predictability for both street and track applications. At 1.75 pounds and compact at 4.3 x 4.3 x 6 inches, it is engineered to fit within tight suspension packaging constraints without compromising performance.
