ICON Vehicle Dynamics K63178L - 23-25 FORD F250/F350 4-5.5" STAGE 8 COILOVER CONVERSION SYS W/ EXPANSION PACKS

ICON 4.5” suspension systems lift your Ford Super Duty while improving ride quality and performance. With endless hours spent testing and tuning our suspension components and shocks, you’ll have the best suspension solution on the market.

This ICON Vehicle Dynamics 4-5.5” coilover conversion system is a great way to lift your 4WD 2023-2026 Ford F-250/F-350 Super Duty while drastically improving ride quality and performance and allowing fitment of larger, more aggressive wheel and tire combinations. This Stage 8 system is perfect for on-road and towing use, as well as job site duty, washboard gravel roads, and more aggressive off-road adventures. ICON's 4-5.5” Lift Stage 8 Coilover Conversion System features 2.5 Series CDEV remote reservoir coilovers that provide superb on-road comfort and off-road performance while at the same time allowing for end-user ride height adjustability. These bolt-in coilovers also allow the option to mount secondary shocks in the stock location, effectively doubling shock damping ability. Their 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. ICON Vehicle Dynamics Ford Super Duty 4-Link kit further improves performance by eliminating suspension bind commonly experienced with factory radius arms during articulation and allows on-vehicle caster angle adjustment. This “freeing up” of the front end and the ability of the 4-Link Kit to maintain positive caster through the range of travel equates to an unparalleled ride quality in all conditions. The fabricated track bar drop bracket allows the axle to be properly centered under the frame and reduces road feedback throughout the steering system with improved on- and off-road manners thanks to the elimination of bump steer. An adjustable track bar allows for on-vehicle adjustment to fine tune track alignment as well as eliminating the deflective OE track bar bushings for an overall more rigid unit to improve the vehicles handling characteristics. ICON’s Centerline steering stabilizer kit features a 2.5 Aluminum Series shock absorber with a piggyback reservoir for improved steering damping compared to ICON dual 2.0 steering stabilizers, better controlling undesirable steering feedback caused by larger tires while also improving ground clearance. Leaf spring expansion packs provide 2" of rear lift over stock with improved ride quality and small bump compliance while also reducing axle wrap compared to lift blocks. ICON 2.5 Aluminum Series CDEV piggyback reservoir rear shocks feature a vehicle specific tune for improved vehicle handling and excellent ride quality on- and off-road with improved performance compared to 2.0 Aluminum Series shocks. Focus on driving and let ICON Intelligent Control (IIC) read the terrain and make near-instant adjustments via the Compression Damping Electronic Valve (CDEV) at each individual shock. Control the system wirelessly through the IIC app on your phone and once configured the system functions without driver input. The included box kit includes fabricated front sway bar drop brackets to prevent bind, heavy-duty aluminum bump stop spacers, and high quality stainless steel extended brake lines. This suspension system features high quality CNC machined, laser cut, and brake formed components and with the endless hours ICON has spent testing and tuning our suspension components and shock absorbers as a complete system, you can rest assured you have the best suspension solution on the market.
