Take Control Of Every Road Every Load

If you're ready to give your Super Duty a serious upgrade, the ICON K64545L 4.5" Stage 5 Suspension System with Expansion Packs brings the kind of performance and flexibility that transforms how your truck handles every mile. Whether you're towing a trailer, hitting rutted backroads, or just looking to clean up your ride stance with more capable suspension, this kit delivers. It lifts your front end 4.5 inches and raises the rear with ICON's leaf expansion packs, giving you 2 inches of lift that rides better than block setups and helps manage axle wrap. The 2.5 CDCV shocks are what really set this system apart, offering 10 levels of external compression adjustment so you can fine-tune your ride depending on what you're hauling or where you're driving. The result is a truck that rides smooth on the road and stays controlled when the terrain gets rough. Steering stabilizer upgrades help keep everything feeling tight and responsive, especially if you're running larger tires. It’s a balanced, purpose-built suspension package that puts you in full control of your ride without giving up comfort or drivability.

Fully Tuned Suspension Built For Demanding Conditions

The Stage 5 system from ICON is designed to give 2023-2025 diesel Super Duty owners advanced suspension tuning, precise control, and real-world durability. It uses ICON’s dual-rate coil springs up front, which are optimized for diesel weight and deliver a soft ride at first compression, then transition to a firmer rate to resist bottoming during towing or off-road use. Rear lift is handled by ICON’s leaf spring expansion packs rather than traditional blocks, which improves ride quality and small bump absorption while reducing axle wrap under load. At the core of this system are CDCV-equipped 2.5 remote reservoir shocks at all four corners, allowing for 10-position external compression damping adjustment to match driving style, terrain, or payload. A Centerline stabilizer with piggyback reservoir improves steering feel and reduces feedback, especially when running oversized tires. The included radius arm drop brackets help maintain proper caster and suspension geometry, while the adjustable track bar centers the front axle and eliminates unwanted movement. From the stainless steel brake lines to the CNC-machined and laser-cut components, every part of this system is designed to work together as a complete, high-performance upgrade.
