Get More From Your Super Duty Suspension

If you're looking to ditch the stock setup and give your Super Duty the ride it truly deserves, the ICON Stage 6 Suspension System with 4-Link is the kind of upgrade that changes everything. This system delivers a 2.5-inch lift while unlocking smoother handling, better wheel travel, and the kind of control that makes towing, hauling, and off-roading feel effortless. The 4-Link setup replaces your factory radius arms and frees up front-end movement, which means better articulation on rough terrain and a more planted feel on the road. Add in ICON's electronically adjustable CDEV shocks and you get real-time damping that adapts on the fly, so the truck feels dialed in no matter the conditions. You can even control and tune the suspension wirelessly using the ICON Intelligent Control app on your phone. It’s a smart system that works behind the scenes to give you confidence wherever you drive. Whether you're daily driving or heading deep into the backcountry, this kit delivers serious capability without sacrificing ride quality.

Precision Suspension Tuning For Real World Performance

The ICON K65918 Stage 6 System with 4-Link combines carefully engineered components that work together as one cohesive upgrade. At the front, dual-rate coil springs provide improved ride quality and additional wheel travel, specifically tuned to handle the weight of diesel engines in 4WD Super Duty trucks. The transition to a 4-Link configuration eliminates binding during articulation and allows for on-vehicle caster adjustment, which helps maintain ideal suspension geometry across the full range of travel. ICON’s 2.5 Series CDEV shocks come with remote reservoirs and electronic compression control, actively adjusting damping to match road inputs and chassis movement. The system also includes a heavy-duty adjustable track bar and a bump steer correction bracket, ensuring tighter steering response and improved alignment. A 2.5-inch Centerline steering stabilizer helps reduce kickback through the wheel, especially useful when running larger tires. With fully serviceable shock components, anodized corrosion-resistant shock bodies, and FK rod ends for lasting strength, this suspension is built for long-term durability and high-performance reliability.
