Take On The Road Ahead With Confidence And Comfort

If you're looking to give your Super Duty a serious boost in both performance and appearance, the ICON Stage 3 4.5" Lift System with Radius Arms is a powerhouse upgrade worth every penny. Built for 2023-2025 Ford F-250 and F-350 diesel trucks, this kit does more than just lift, it transforms the way your truck handles on the road, off the pavement, and everywhere in between. The custom-tuned 2.5 Series shocks paired with dual rate coil springs help your truck float over rough terrain without losing control or comfort. Whether you’re towing a loaded trailer down the highway or navigating rutted backroads, the ride stays stable and responsive. The addition of ICON’s heavy-duty radius arms not only improves strength and ground clearance but also eliminates the need for drop brackets, keeping your setup clean and efficient. It even features on-vehicle caster adjustment, which gives you more control over how your truck tracks and steers. If you want a lift kit that feels like a complete overhaul, in all the right ways, this is the one that delivers.

Tuned For Control Clearance And Real World Loads

This Stage 3 system from ICON is engineered to handle the demands of work, off-road travel, and everyday road duty with a balanced, performance-focused design. The dual rate coil springs up front provide 4.5 inches of lift, with a soft initial response for daily driving and a firmer secondary rate that kicks in during compression to prevent bottoming out under load. ICON’s 2.5 Aluminum Series shocks with internal reservoirs are precision-tuned for the Super Duty platform and feature 7/8-inch shafts with hard anodized bodies for long-lasting durability. Replacing the factory arms, ICON’s fabricated radius arms improve overall strength, increase ground clearance, and provide additional tire clearance at full steering lock. They also come with built-in caster cams, allowing for on-vehicle caster adjustment to dial in alignment without the hassle. The track bar drop bracket realigns front-end geometry to eliminate bump steer, while the dual opposing steering stabilizers improve road feel, especially when running oversized tires. Heavy-duty rear lift blocks and stainless steel brake lines round out the package, making this a well-rounded system designed for trucks that work hard and play even harder.
