Product Description

The Eibach 0700.225.0400 is an ERS linear main spring built for coilover and motorsport suspension systems that use a 2.25-inch inner diameter spring. With a 7.00-inch free length and a 400 lbs/in linear spring rate, it is intended for suspension tuning where precise spring consistency, predictable handling response, and repeatable performance 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, 7.00-inch free length, and 400 lbs/in rate. A second trusted source aligns the supporting dimensional family data and lists a 2.68-inch block height for this exact part number. 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, preload, and coilover configuration.
