Eibach ERS 22.00-Inch Coil-Over Spring, 3.75-Inch Inside Diameter, 800 lb/in Spring Rate

Eibach ERS 22.00 in. Length x 3.75 in. ID Coil-Over Spring

The Eibach ERS Coil-Over Spring is engineered for demanding motorsport, performance driving, and competition suspension applications. This linear-rate spring features a 22.00-inch free length, 3.75-inch inside diameter, and an 800 lb/in spring rate to provide predictable suspension response and consistent handling characteristics. Its design supports precise chassis tuning by allowing suspension builders and vehicle engineers to select spring rates matched to a specific setup.

Built with Eibach’s performance-focused spring technology, the ERS spring is suitable for use with compatible coil-over suspension systems and spring hardware. The linear spring rate delivers uniform resistance throughout compression, helping provide repeatable vehicle behavior during braking, cornering, acceleration, and load transitions. The 3.75-inch inside diameter is intended for compatible coil-over platforms, while the extended free length accommodates applications requiring additional suspension travel or setup flexibility.

Use the Eibach part number EIB2200.375.0800S when verifying compatibility with your suspension system, spring perch, and retaining hardware. Professional installation is recommended, and proper suspension setup should include confirming installed height, available travel, preload requirements, and spring clearance before vehicle operation. This automotive performance component is not supplied as a universal fitment for every vehicle; application-specific fitment data should be confirmed with the vehicle and coil-over manufacturer.
