The Eibach ERS 70mm ID Linear Tender Spring is an individually tested motorsport spring designed to refine suspension performance in demanding racing applications. As part of Eibach’s extensive catalog of precision-engineered race springs, this tender spring helps chassis builders and race teams fine-tune handling dynamics across a wide range of vehicle setups.

When paired with a main spring, the Eibach ERS tender spring provides a softer initial spring rate. This characteristic can improve suspension compliance and help maintain spring contact during unloaded or transitional suspension conditions. The linear rate delivers predictable, consistent performance throughout the spring’s working range, making it a practical choice for applications where repeatable suspension behavior is essential.

Every spring is individually tested to support reliable quality and rate consistency. The Eibach ERS 70mm ID Linear Tender Spring is intended for motorsport suspension systems and may be used with compatible shocks, coilover assemblies, or other racing suspension components. Confirm spring dimensions, rate requirements, installed height, and suspension compatibility before installation. This product is supplied as one individual spring. No vehicle-specific fitment data was provided.
