Our Cadillac Extreme front suspension system was designed to provide the ultimate slammed stance. The Cadillac system incorporates non-binding geometry that eliminates wear, alignment and drivability associated with lesser systems. The system is capable of laying a 29" tall tire and is compatible with factory drum or aftermarket disc brakes. The kit comes complete with upper and lower control arms with bushings, air bag cups, and adjustable control arm brackets. This kit does NOT provide provisions for shocks.
