Make Your Super Duty Ride As Good As It Looks

If you're serious about lifting your Super Duty and want something that actually improves how your truck rides, the ICON Stage 3 Suspension System with Expansion Packs is a rock-solid choice. Designed specifically for 2023-2025 F-250 and F-350 gas 4WD models, this kit delivers on both performance and comfort, whether you're headed to the job site, towing down the highway, or hitting a backroad trail. You’ll get a true 4.5 inches of front lift and 2 inches in the rear, which gives you room for larger tires without wrecking your ride quality. The rear expansion packs are a standout here, they improve compliance over rough surfaces and eliminate the harsh feel that traditional lift blocks often create. Add in the dual steering stabilizers and high-performance 2.5 shocks, and your truck instantly feels more planted, especially with wider wheels and tires. It’s the kind of suspension setup that makes your truck feel more capable without making it feel overbuilt or uncomfortable. If you’re building a truck that has to work and play without compromise, this system checks every box.

Engineered Suspension Built For Trucks That Do More

The ICON Stage 3 4.5" Lift System with Expansion Packs is a complete suspension upgrade built for owners who expect more than just added height. It starts with ICON’s dual rate front coil springs, which are tuned specifically for the weight and dynamics of gas-powered Super Duty trucks. These springs provide a soft, controlled feel over small bumps while progressively firming up as the suspension compresses deeper into its travel. Matching 2.5 Aluminum Series shocks with internal reservoirs are installed at all four corners, offering increased oil capacity and better heat management during extended use. Out back, leaf spring expansion packs deliver a smoother ride and improved axle wrap control compared to basic lift blocks. The included radius arm and track bar drop brackets correct suspension geometry and caster for proper alignment and improved handling. Dual steering stabilizers reduce unwanted feedback, making the truck easier to control when running larger tires. Every component in this kit is bolt-on and backed by ICON’s lifetime warranty on springs and fabricated parts, ensuring long-term durability and real-world performance.
