ICON 2-4″ Lift kit Stage 4 Billet System for 2021-2023 Ford Bronco 2WD/4WD Suspension

ICON 2021-2023 Ford Bronco (Non-Sasquatch) 3-4 inches Lift Stage 4 Suspension System (Billet)

Part Number: K40004

Summary: The ICON Stage 4 Suspension System provides a 3-4” front and 2-3” rear lift height for the 2021-2023 Ford Bronco (Non-Sasquatch), engineered to maximize wheel travel and damping performance. This system integrates 2.5 Series remote reservoir coilovers to significantly increase oil volume and heat dissipation, ensuring consistent performance during aggressive off-road use. A key differentiator is the inclusion of Billet Aluminum Upper Control Arms featuring the patented Delta Joint Pro, providing 90 degrees of articulation and on-vehicle alignment adjustability.

Features

• Remote Reservoir Coilovers: Vehicle-specific tuned 2.5 Series shocks provide increased oil volume and heat dissipation to ensure sustained damping performance and resist fade under hard use.
• Delta Joint Pro: Patented (U.S. Pat. 10,731,700) heavy-duty ball joints provide 90 degrees of total articulation to ensure maximum suspension droop and bind-free travel.
• Billet Upper Control Arms: 6061 CNC-machined aircraft-grade aluminum provides increased strength and durabilty to ensure on-vehicle caster/camber adjustment for optimum drivability.
• Triple Rate Rear Coils: ICON-engineered coil springs provide a unique triple-rate design to ensure superior ride quality and performance for near-stock weight vehicles.
• System Durability: CAD-plated shock bodies with 7/8” shafts and PTFE-lined spherical bearings provide superior corrosion resistance to ensure long-term component reliability.
• Installation: 100% bolt-on design provides a simplified upgrade path to ensure no drilling, cutting, or welding is necessary for install.

Frequently Asked Questions

Can I run 37 inches tires with this Stage 4 system?
Yes, but it requires the use of front up-travel limiters (#611075), rear up-travel limiters (#611074), and significant trimming/modifications. Crash bar removal may be required but is not recommended.

What is the benefit of the Remote Reservoir on this kit?
The remote reservoirs increase the total oil capacity and surface area of the shock, which allows for better heat dissipation and prevents “shock fade” during high-speed or prolonged off-road use.
