Skyjacker F8601KS-X 6 in. Suspension Lift System with ADX 2.0 Remote Reservoir Monotube Shocks

The Skyjacker F8601KS-X is a complete 6-inch suspension lift system engineered specifically for the 2008 Ford F-250 Super Duty 4WD with a gas engine. This comprehensive kit delivers a commanding lift while maintaining factory-like ride quality and proper alignment geometry — both on the street and off the beaten path.

At the heart of this system are Skyjacker's premium ADX 2.0 Adventure Series Remote Reservoir Aluminum Monotube Shocks, which significantly enhance front and rear damping capacity. The shocks feature a race-inspired full-displaced valving system and utilize Internal Floating Piston (IFP) technology for the quickest shock reaction time. The separate remote reservoir increases oil capacity for consistent performance under extreme conditions, while the impact-extruded, CNC-machined T6061-T6 aluminum monotube body dissipates heat more efficiently than traditional steel-bodied shocks — and weighs less too.

Key Features:

• Race-inspired full-displaced valving system for consistent damping
• Nitrogen-charged with Internal Floating Piston (IFP) technology
• Teflon-banded piston for smooth reaction and superior terrain stability
• CNC-machined T6061-T6 aluminum monotube body for superior heat dissipation
• Skyjacker Softride® coil spring technology using 5160H chromium alloy material

• Includes all necessary mounting hardware and detailed step-by-step installation instructions
• Backed by Skyjacker's limited lifetime warranty

Skyjacker's Softride® technology uses an advanced shot-peening and presetting process that eliminates spring sag and extends coil spring life. The radius arm drop brackets reposition the OEM radius arm mounts at the frame to maintain correct caster for proper alignment, while the heavy-duty track bar relocation bracket locks the front crossmember on both sides to prevent movement in this high-stress area. This lift system opens the door for larger aggressive off-road tires, greater ground clearance, and a bold, ready-for-action stance — without sacrificing everyday drivability.
