Crafted by Eibach, this spring features a 2.99-inch length and a 70mm inner diameter, making it suitable for a variety of custom suspension setups. The system utilizes a Main and Tender spring concept, where the Tender spring provides a softer initial compression, improving comfort and traction during initial load.

The linear-rate characteristic of the Main spring allows for predictable performance, while the variety of available Tender spring rates offers customization options to suit different driving styles and conditions. Constructed from durable materials, this spring is engineered for longevity and consistent performance under demanding conditions.

Designed for use in custom or aftermarket suspension systems, the Eibach ERS 70mm ID Linear Tender Spring is suitable for applications requiring precise tuning of initial and final spring rates. It is compatible with a range of vehicle makes and models, particularly those with suspension setups that accommodate a 70mm inner diameter spring. The spring is ideal for street, track, or off-road use where adjustable ride characteristics are desired. Installation involves replacing or upgrading existing springs with this direct-fit component, ensuring a straightforward upgrade process. The kit includes the tender spring itself, with no additional components required. This spring provides a versatile solution for enthusiasts seeking improved ride comfort and handling performance across various driving scenarios.
