Let Your Gas Super Duty Ride The Way It Should

If your 2023-2025 Ford F-250 or F-350 gas truck feels like it's riding stiff or lacking control, the ICON Stage 6 2.5" Suspension System with 4-Link and Expansion Packs changes everything. This system gives you the lift you want with the comfort, capability, and control your truck needs, whether you're working hard during the week or heading off the grid on the weekend. The 4-Link setup allows your front suspension to move more freely, helping your truck ride smoother and stay more predictable over uneven terrain. Rear expansion packs improve ride quality in the back end while reducing axle wrap, especially when towing or hauling heavy loads. ICON's CDEV shock system takes things further by reacting in real time to terrain changes, automatically adjusting damping to keep your ride dialed in. You can also fine-tune the system wirelessly through the ICON IIC app right from your phone. Every piece of this kit is bolt-on, built for gas-specific setups, and tested to handle everything from job site abuse to rugged trails.

Suspension Control Engineered For Real World Gas Power

The ICON K65919L Stage 6 Suspension System brings together performance-tuned components that are purpose-built for gas-powered 2023-2025 Super Duty 4WD trucks. Up front, dual-rate coil springs deliver 2.5 inches of lift and are calibrated specifically for the lighter weight balance of gas engines, ensuring a smooth ride without sacrificing payload or handling. The upgrade to a 4-Link system eliminates binding commonly found in factory radius arm setups, while maintaining consistent caster angles throughout suspension travel. ICON’s 2.5 Series CDEV shocks with remote reservoirs automatically adjust compression damping based on vehicle movement, G-forces, and user settings through the IIC app. In the rear, leaf spring expansion packs, U-bolts, and cast blocks provide a more compliant ride and better traction, especially when the truck is loaded. The adjustable front track bar and bump steer bracket correct geometry and improve steering response after the lift. Dual ICON steering stabilizers come standard for added control and reduced feedback through the wheel. Built with serviceability in mind and backed by ICON’s reputation, this system offers unmatched tuning flexibility and real-world durability.
