The Eibach ERS rear spring measures 13 inches in length with a 5.00 inch outside diameter, finished in platinum for rear suspension applications. It is intended as a direct-form spring for coilover or spring-replacement work where those dimensions are required, helping installers maintain intended ride height and spring characteristics during rear suspension setup or maintenance.
