Product Description

The Eibach 0700.225.0700 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 700 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 product data confirms this spring as an ERS Linear Main Spring with 2.25-inch inner diameter, 7.00-inch free length, and 700 lbs/in rate. A second trusted retailer source aligns the supporting dimensional specs, including 57.15 mm I.D., 177.80 mm length, 3.390-inch block height, 3.610-inch travel, and 2,527-pound load at block height, while another specialist retailer lists essentially matching metric values and a 2.9-pound weight. 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.
