Product Description

The Eibach 1200.300.0600S is a Race Off-Road linear coil spring built for off-road and custom coilover applications that use a 3.00-inch inner diameter spring. With a 12.00-inch free length and 600 lbs/in spring rate, it is intended for suspension tuning where predictable rate control, long installed height, and repeatable performance are required. This is a universal spring sold individually, not a vehicle-specific lowering or lift kit.

Official Eibach product data confirms this exact part number as a single Race Off-Road spring with 3.00-inch inside diameter, 12.00-inch length, and 600 lbs/in rate. A second trusted retailer source aligns the exact dimensional specs, confirms it is a non-progressive single spring, and lists the finish as red for this SKU. Because this is a universal spring, vehicle-specific fitment should never be assumed. Lift or drop height cannot be stated because installed ride height depends entirely on vehicle corner weight, motion ratio, preload, and shock configuration.
