Upgrade Your Gas Super Duty Without Compromising Ride Quality

If you’re looking to turn your 2023-2025 gas-powered F-250 or F-350 into a truck that rides smoother, drives straighter, and performs better across the board, the ICON Stage 6 2.5" Suspension System with Radius Arms and Expansion Packs delivers on all fronts. This setup offers a refined balance of on-road comfort and off-road confidence, giving you extra ground clearance and control without sacrificing your truck’s everyday drivability. ICON’s CDEV shock technology adapts automatically to changing terrain, so the suspension does the work for you, whether you're towing, hauling, or crawling through backcountry trails. You can dial in your preferences through the ICON Intelligent Control app, then just let it run in the background while you drive. Rear expansion packs help keep axle wrap in check and smooth out the ride over rougher sections. Meanwhile, the radius arms are built strong and shaped to clear larger tires with ease, giving you room for 37s with the right setup. It’s all bolt-on, built to last, and tuned specifically for gas-powered Super Duty trucks, so you can feel the difference from the first mile.

Intelligent Suspension Tuning Matched To Gas Applications

The ICON K65919RL Stage 6 Suspension System is engineered for precise control, dependable ride quality, and advanced tuning for 2023-2025 Ford F-250 and F-350 4WD gas trucks. Dual-rate coil springs up front provide 2.5 inches of lift while maintaining smooth transition through varying terrain, and they're specifically tuned for the weight balance of gas engine configurations. ICON’s 2.5 Series CDEV shocks feature piggyback reservoirs and use electronic valves to make real-time adjustments based on chassis feedback and driving conditions. These adjustments are managed automatically by the ICON Intelligent Control system, which can also be configured wirelessly through a mobile app. Rear expansion packs, U-bolts, and blocks help manage suspension movement and reduce axle wrap, keeping the rear end planted during heavy acceleration or rough trail sections. The fabricated radius arms use sealed pivot bushings to minimize road feedback and come with built-in caster adjustment for improved alignment control. A dual steering stabilizer setup enhances handling, especially when running larger tires or navigating rugged terrain. With fully serviceable components and a no-cut install process, this system delivers long-term performance without compromise.
