The ICON Vehicle Dynamics Stage 4 Suspension System for the 2021-2023 Ford Bronco features ICON's 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 2-3” of front lift and 1.25-2.25” of rear lift over stock 4-door Broncos with 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 Tubular Upper Control Arms which provide caster correction and feature ICON's patented Delta Joint PRO, which allows for up to 90-desgrees freedom of movement. The rear 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).
