Ground Control Coil-Over 1505.02

Ground Control has been building suspension kits for almost 20 years ? and with that much experience in engineering suspension systems, just imagine what that experience can do for you and your cars handling! Whether you are weekend warrior or a boulevard cruiser, Ground Control coil-over suspension kits are designed for superior handling without sacrificing a lot of ride quality. After several years of use in racing applications, these kits have been fine-tuned and adapted for street use. Ground Control coil-over kits give you the option to customize the ride height of your vehicle with ease. Simply lift the corner(s) of the vehicle and spin the adjustable spring seat up or down by hand to raise or lower the ride height (some applications require the use of a provided wrench). All adjusters consist of a threaded sleeve and adjustable spring seat that is made using high strength 6061-T6 aluminum and are anodized for greater durability and appearance. The threads on the adjusters are square cut, which locks the adjustable spring seat in place securely under load. For further precaution, a setscrew in the adjustable spring seat can be used to secure the adjustment, while upper spring perches are used to insulate the spring. Ground Control coil-over kits feature Eibach springs and offer a lifetime warranty against spring rate change and sagging. Ground Control works very closely with Eibach to ensure that the provided springs are made with the highest standards that are demanded by todays tuners. Ground Control coil-over suspension kits are backed by a lifetime warranty and all made in the USA. Designed to be used with either OEM or specific aftermarket shocks (see below).
