The Eibach ERS XT barrel spring, 6.0 in length x 2.50 in inside diameter with a 2.28 in block height, provides an extreme-travel spring option for coilover systems where extended compression and progressive spring action are needed. The ERS specification focuses on dimensional match for use with compatible shock bodies and spring seats; installers should confirm ID and block height match their coilover hardware before selection.
