The Eibach 1400.300.0600S is a 14-inch coilover spring with a 3.00-inch inside diameter and a 600 lbs/in rate, finished in silver. Length: 14.00 in | Rate: 600 lbs/in Eibach's page lists it as a single spring, and the company offers its 3.00-inch inside-diameter coilover springs in a broad selection of rates and lengths, so you can dial in a specific rate for a track or performance build.
The manufacturer's chart gives the figures that matter when planning a setup: a block height of 6.26 inches, 7.74 inches of travel, and a 4,638 lb block load. Those numbers show how far the spring can compress before it goes solid, which is the question to answer when comparing it with an unbranded coil that offers no documented rate or travel. The manufacturer also lists the spring at 356 mm long with a 76 mm inside diameter, which helps when checking metric measurements against your coilover body.
Vehicle application is not confirmed in the manufacturer's listing, so verify the 14-inch free length and 3.00-inch inside diameter against your coilover body, perch, and spring seat before ordering. Searches for a 600 lb/in coilover spring, a 14 inch free length 3 inch ID coilover spring, or a silver Eibach coilover spring will find this part number. Sold as a single spring, it weighs 9.72 lbs.
