Give Your Super Duty The Ride It Was Built For

If your 2023-2025 Super Duty already looks the part, it’s time to make sure it performs like it too. The ICON Stage 8 Suspension System with Radius Arms delivers a complete ride transformation that keeps up with everything you throw at it, from heavy towing and job site hauling to off-road weekends with the crew. This kit doesn’t just lift your truck 4.5 inches, it completely changes how it handles, responds, and rides. ICON’s CDEV-equipped shocks work with the Intelligent Control module to automatically adjust compression as terrain changes, keeping the ride smooth and predictable without constant driver input. The fabricated radius arms not only boost strength but also offer better tire clearance and ground clearance without drop brackets. Whether you’re climbing steep trails or cruising pavement, the added stability and comfort are instantly noticeable. And with adjustable track bar geometry, improved steering feedback, and a set of remote reservoir shocks built to handle serious heat, this setup is designed to work as hard as your truck does.

Advanced Radius Arm Suspension Tuned For Real Performance

The ICON K65907R Stage 8 Suspension System is engineered to bring balanced ride quality and trail-ready durability to 2023-2025 Ford Super Duty diesel 4WD trucks. This system replaces factory components with upgraded dual rate coil springs, precision-tuned 2.5 CDEV shocks, and fabricated radius arms designed for strength and adjustability. The Intelligent Control module works with onboard sensors to instantly adjust compression damping at each shock, reacting to changing G-forces and terrain in real time. ICON’s radius arms feature maintenance-free bushings, built-in caster cams for on-vehicle alignment, and better clearance at full steering lock. The heavy-duty track bar bracket corrects steering geometry and bump steer, while the adjustable track bar eliminates deflection common with stock bushings. Rear lift is handled by 5-inch fabricated blocks and extended U-bolts, ensuring a stable stance under heavy towing or off-road articulation. Stainless brake lines, sway bar drop brackets, and bump stop spacers round out a system that’s as complete as it is capable, all backed by ICON’s reputation for quality and long-term support.
