The Eibach ESS Speedway Front Spring is an individually tested motorsport spring engineered for race applications that demand precise handling control and consistent performance. Designed with a 350 lb/in spring rate, this front spring helps racing teams fine-tune chassis balance, suspension response, and cornering behavior across a wide range of track conditions.

Eibach race springs are developed for customization and performance optimization in professional and enthusiast motorsport applications. The ESS design minimizes side loads while positioning the load center ideally in relation to the spring axis. This helps promote smooth, predictable operation throughout the suspension’s usable travel. The spring also provides maximum travel with minimal block height, supporting efficient suspension packaging and reliable race setup adjustments.
