Skyjacker F8651KS-X 6 in. Suspension Lift System with ADX 2.0 Remote Reservoir Monotube Shocks

The Skyjacker F8651KS-X is a complete 6-inch suspension lift system engineered specifically for the 2008 Ford F-250 Super Duty 4WD with a diesel engine. This full system delivers a significant lift that opens the door to running aggressive 36-inch off-road tires while dramatically increasing ground clearance and overall stance.

At the heart of this system are Skyjacker's 2-Stage Variable Rate Front Coil Springs, purpose-built for the added weight demands of the diesel-powered Super Duty. The first flex rate stage delivers a compliant, comfortable ride during normal driving and allows the suspension to flex freely at full droop, while the second rate stage only engages under heavier compression — resulting in a controlled, smooth ride whether on the highway or tackling demanding terrain.

Geometry correction components are included to maintain proper factory alignment specifications after the lift. Radius arm drop brackets reposition the OEM radius arm mounts at the frame to preserve correct caster angles, and an ultra heavy-duty track bar relocation bracket captures the front crossmember on both sides to prevent lateral movement and keep the front axle properly centered. Sway bar links are also included to realign the front sway bar working angle for maximum sway control.

The system is paired with Skyjacker's ADX 2.0 Adventure Series Remote Reservoir Aluminum Monotube Shocks at all four corners. These shocks feature a race-inspired full-displaced valving system and are nitrogen-charged with Internal Floating Piston (IFP) technology for the quickest shock reaction time and superior damping performance on and off the road. The remote reservoir design provides increased fluid capacity to resist fade under sustained off-road use.
