IntroductionA coilover is an automobile suspension device. Thanks to built-in adjustability, coilovers offer the ability to be shortened or lengthened - lowering or raising the ride height of your vehicle through manual adjustment, without complex electronics or hydraulics. A coilover kit consists of a damper and a shock absorber with a coil spring around it.
