The Eibach ERS 4.00 in x 3.00 in coil-over spring is part of Eibach’s ERS Race Spring System and intended for coil-over suspension applications that require a 3.00 in inner diameter. With a 4.00 in free length it fits perches sized for those dimensions. As an ERS product, it is produced in series to tight tolerances to deliver linear spring characteristics and consistent quality for tuning and competition use.
