Configured with Rear Leaf Springs for a level stance from front to rear, maintaining factory payload weight ratings with a multi-leaf progressive design. Includes NX2 Nitro Series shocks featuring a nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, 1-3/8-inch high-flow piston, dual-welded ends for increased strength, self-lubricating seals, and a silver powder coat finish with vehicle-specific valving for better control.
Overview
This 6-inch lift kit with 4-link conversion is designed for 2008–2010 Ford Super Duty F250 and F350 gas trucks. The kit improves stance, performance, and capability, providing clearance for up to 37-inch tires. Up front, the kit includes gas-specific Pro-Ride coil springs, heavy-duty 4-link control arms, a forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, brake line brackets, and custom-tuned nitrogen charged shocks. In the rear, the base kit utilizes high-strength lift blocks, longer U-bolts, brake line brackets, and a matching set of shocks. The 4-link conversion replaces the factory stamped steel radius arms with BDS upper and lower control arms mounted via high-strength 1/4-inch steel brackets to correct axle positioning and limit caster change throughout wheel travel.
