Description
Part #: K40004X
The ICON Vehicle Dynamics Stage 4 Suspension System for the 2021-2023 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.
Features:
- Improved suspension performance and ride quality over stock
- Up to 11.5" front / 14" rear wheel travel with 35" tire fitment
- Vehicle specific tuned remote reservoir front and rear coilover shocks for superior damping and vehicle control, even under hard use
- Adjustable coilovers yield up to 3-4" of front lift height and 2-3" of rear lift height over stock 4-door Broncos without the Sasquatch package
- PTFE lined spherical bearings and application specific mounting hardware
- 6061 Aircraft grade aluminum CNC machined components
- Corrosion resistant CAD plated coilover shock bodies with 7/8" diameter shafts
- ICON engineered coil springs featuring a unique dual rate rear coil design with increased spring rates for heavier equipped Broncos
- High strength alloy CNC machined lower bar pins
- Billet aluminum UCAs for added strength, durability, and on-vehicle caster/camber adjustment for optimum drivability
- UCAs feature the patented (U.S. Pat. 10,731,700) Delta Joint Pro with 90 degrees of total articulation.
- 100% Bolt-on system - no drilling, cutting, or welding necessary for install
