Product Description

The Eibach 0600.225.0500 is an ERS linear main spring built for coilover and motorsport suspension systems that use a 2.25-inch inner diameter spring. With a 6.00-inch free length and a 500 lbs/in linear spring rate, it is intended for suspension tuning where precise spring consistency, compact packaging, and repeatable handling response are required. This is a single spring, not a vehicle-specific lowering kit.

Official Eibach catalog data confirms this spring as an ERS Linear Main Spring with 2.25-inch inner diameter, 6.00-inch length, and 500 lbs/in rate, while a second trusted retailer source confirms the supporting dimensional specs including 57 mm I.D., 152 mm length, 88 N/mm rate, 62 mm block height, 90 mm travel, and 1770 lb block load. Because this is a universal motorsport spring, vehicle-specific fitment should never be assumed. Lift or drop height cannot be stated because installed ride-height change depends entirely on the vehicle, corner weight, motion ratio, and coilover configuration.
