This Stage 8 kit comes with Billet Aluminum Upper Control Arms which provide on-vehicle caster and camber adjustability and feature our patented Delta Joint PRO, which allows for up to 90-degrees freedom of movement. The billet rear links have been designed to free up suspension bind, offer on-vehicle pinion angle adjustment, and optimize clearance from the fuel tank during maximum articulation and feature greaseless bushings and massive FK rod ends. The Adjustable Track Bar also features our dual-durometer greaseless bushing and an FK Rod End, as well as on-vehicle adjustability for perfectly aligning the Bronco's rear axle for any lift height. The rear CDEV coilovers are mounted in a shaft up orientation and feature unique ICON engineered progressive dual rate coil springs that provide extra weight capacity for those who frequently load out their Broncos with extra gear and equipment while maintaining excellent on- and off-road performance characteristics. This suspension system is designed to provide up to 11.5" of front suspension travel and 14" of rear suspension travel when used with 35X12.50 tires. It may be safely used with 37" and larger tires if using the optional up-travel limiters (sold separately).
