Product Description

ICON 2005-2007 Ford F-250/F-350 Super Duty 4WD 4-5.5" Lift Stage 4 Coilover Conversion System w/ Radius Arms (K63114R)

The ICON Vehicle Dynamics Stage 4 Coilover Conversion System is a premium suspension upgrade engineered for 2005–2007 Ford F-250 and F-350 Super Duty 4WD trucks. Designed to replace traditional coil spring setups with high-performance coilovers, this system delivers superior ride quality, increased wheel travel, and enhanced damping control. Ideal for both on-road comfort and aggressive off-road use, it provides a significant performance upgrade over standard lift kits.

Adjustable 4–5.5” Lift for Maximum Clearance

This system offers adjustable ride height from 4 to 5.5 inches, allowing you to fine-tune your truck’s stance, improve ground clearance, and fit larger wheel and tire combinations. The adjustability ensures optimal performance for both daily driving and off-road conditions.

2.5 Series Remote Reservoir Coilovers

ICON 2.5 Series remote reservoir coilovers provide exceptional damping performance and heat dissipation. These shocks are vehicle-specific tuned to deliver consistent performance under heavy loads and demanding terrain, improving both control and ride comfort.

Radius Arm System for Strength and Geometry

This Stage 4 system includes ICON’s heavy-duty radius arm system featuring a fully boxed design for maximum strength and durability. The sealed pivot bushings reduce road noise and vibration while ensuring long service life and smooth operation.

Optimized Clearance for Larger Tires

The radius arms are engineered with a profile that improves clearance at full steering lock, allowing fitment of up to 37-inch tires without interference. This design enhances both off-road capability and overall vehicle functionality. 

Improved Ride Quality and Handling

By converting to a coilover-based suspension, this system significantly improves ride quality, reduces body roll, and enhances overall handling characteristics. The result is a smoother, more controlled ride both on pavement and off-road.

Complete Bolt-On Coilover Conversion

Designed as a bolt-in system that mounts in the factory coil bucket location, this conversion requires no major fabrication. It provides a straightforward installation while delivering professional-level suspension performance gains.
