The Eibach ESS Speedway Conventional Single Rear Coil Spring with a 400 lbs/in rate and a 1.46-inch block height is crafted for serious performance and racing applications. As part of Eibach's renowned ERS race spring system, this coil spring features a highly linear spring rate and tight manufacturing tolerances, ensuring consistent, predictable handling and superior durability. Built with precision engineering and high-quality materials, it provides increased stiffness and support for aggressive driving, track use, or high-performance setups. Its design enhances suspension response, stability, and load handling, making it a reliable upgrade for demanding motorsport environments.
Designed to fit vehicles requiring a 1.46-inch block height and a 400 lbs/in spring rate, this coil spring is a direct replacement for stock components on compatible rear suspension systems. It is ideal for race cars, track days, or performance street builds where increased spring stiffness is desired. Installation involves standard coil spring replacement procedures, and it works best when paired with suitable shocks and suspension parts to achieve optimal handling characteristics. The spring's robust construction ensures long-lasting performance under high loads and intense driving conditions.

Overview
Overview
Eibach's ERS line has evolved over the years to be the world's most prominent, comprehensive and superior Race Spring System. Eibach Race Springs are all manufactured in series production, often repeated, with a strong manufacturing experience. Thus, Eibach constantly achieves the most linear spring characteristic (rate) while maintaining the lowest tolerances and the highest quality in the industry.

Standard Features
- Rear springs absorb shocks and vibrations from the road, ensuring that the vehicle's body and passengers experience less impact from bumps, potholes, or rough terrain.
- The stiffness of the spring, or its spring rate, determines how much load the spring can bear before compressing. A higher spring rate supports heavier loads, while a lower rate provides a softer ride.
- Rear springs are built from high-strength materials such as steel, allowing them to endure repeated compressions and expansions without losing their shape or performance.
- By maintaining vehicle stability, rear springs reduce the risk of the vehicle bottoming out or losing traction. This enhances safety, especially when driving on rough or uneven surfaces.
- In vehicles designed for off-road use, rear springs are critical for managing rough terrain and heavy loads. Leaf and coil springs, in particular, are popular for their ability to handle rugged conditions.
