Eibach ERS 60mm ID Progressive Tender Spring EIB50-60-0040/0120

The Eibach ERS 60mm ID Progressive Tender Spring is designed for high-performance suspension systems that require controlled spring engagement and improved transition between suspension stages. Its progressive-rate design helps maintain contact and stability as the suspension moves through its travel, supporting more predictable handling during aggressive driving and changing road conditions.

Built for motorsport and performance automotive applications, this Eibach ERS spring is intended to work with compatible 60mm inside-diameter spring hardware. The tender spring design helps manage unloaded or lightly loaded suspension conditions before the primary spring becomes fully active. This can improve suspension response, help reduce abrupt transitions, and support consistent vehicle behavior in demanding driving environments.

The Eibach part number EIB50-60-0040/0120 identifies this specific progressive tender spring configuration. It is suitable for custom suspension setups where spring compatibility, rate selection, and available travel must be carefully matched to the vehicle and damper system. Confirm application requirements, spring perch compatibility, and suspension tuning specifications before installation. Professional installation and alignment are recommended when modifying suspension components.
