Give Your Super Duty The Lift It Was Built For

If you're looking for a suspension system that does more than just lift your truck, the ICON Stage 3 System with Radius Arms and Expansion Packs delivers the performance and confidence serious Super Duty owners expect. This setup is built for 2023–2025 F-250 and F-350 gas models and gives your truck a true 4.5 inches of front lift and 2 inches in the rear. It not only clears bigger tires but transforms the way your truck handles on-road, off-road, and everywhere in between. The included expansion packs offer a smoother ride out back and reduce axle wrap that can affect stability when towing or carrying a load. Up front, fabricated radius arms bring more strength and control, especially when pushing through rough terrain or tight turns. You’ll notice tighter steering, better alignment, and a more balanced ride even with oversized tires, thanks to the dual steering stabilizers and 2.5 performance-tuned shocks. Whether you're cruising highways, climbing rocky trails, or hauling tools to the job site, this kit gives your Super Duty the lift it needs without giving up comfort or control.

Tuned Suspension Geometry That Works On And Off Road

The ICON K65912RL Stage 3 System is designed to offer long-term durability and dialed-in suspension performance for gas-powered 2023–2025 Super Duty trucks. At the core of this kit are ICON's dual rate coil springs, which balance daily driving comfort with off-road capability by delivering a smooth initial ride and firmer compression during deep travel. The included 2.5 Aluminum Series internal reservoir shocks are valved specifically for the Super Duty’s weight and offer better oil volume and thermal stability compared to smaller 2.0 shocks. Instead of relying on basic lift blocks, this system uses leaf spring expansion packs in the rear for improved ride quality, especially when handling uneven surfaces or hauling. Fabricated radius arms with integrated caster cams help correct front-end geometry without the need for drop brackets, which also increases ground clearance under the chassis. A track bar drop bracket helps reduce bump steer while keeping the front axle properly centered under load. Stainless steel brake lines, sway bar drop brackets, and aluminum bump stop spacers complete the package, making this a true bolt-on upgrade built to last.
