Description

SUSPENSION SYSTEM

The ICON Vehicle Dynamics Stage 4 Suspension System for the 2021-UP Ford Bronco features our precision-manufactured, custom valved remote reservoir coilover shocks to yield the maximum travel possible along with superior ride quality and suspension performance both on and off-road. These coilovers also allow for the adjustment of ride height to yield 3-4” of front lift and 2-3” of rear lift over stock 4-door Broncos without the Sasquatch Package. To provide for sustained shock performance at speed through rough terrain, Stage 4 adds remote reservoirs to the ICON Coilovers. Remote reservoirs greatly increase shock oil volume and heat dissipation surface area to resist overheating and cavitation under hard use, which can lead to damper fade. To accommodate the increased travel and lift height afforded by the ICON Coilovers, this Stage 4 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-desgrees freedom of movement. The rear shocks are oriented shaft-up with unique triple-rate coil springs to achieve the most rear suspension travel and the best ride quality possible. 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). The factory crash bars on non-Sasquatch equipped Broncos must be removed to clear 35" and larger tires, but ICON now offers a replacement High Clearance Crash Bar set for those who would like to run larger tires and retain the functionality of the crash bars.
