Superlift K878F 6-Inch Suspension Lift Kit with Fox 2.0 Performance IFP Shocks

The Superlift K878F is a complete 6-inch coil spring suspension lift kit engineered specifically for 2011–2016 Ford F-250 and F-350 Super Duty 4WD trucks with a diesel engine.

At the heart of the front suspension upgrade are engine-specific lifted coil springs designed to achieve the correct 6-inch lift height while preserving the factory ride character of the heavy-duty Super Duty platform. Radius arm drop brackets restore proper caster angle and alignment geometry after the lift, while a track bar relocation bracket eliminates axle bind, roll, yaw, and steering wheel kick that would otherwise occur at lifted ride heights. The factory steering stabilizer is repositioned to its optimal operating angle, and front anti-sway bar extensions maintain proper sway bar function. A drop pitman arm and brake line brackets round out the front-end hardware.

The rear of the truck is addressed with a block and u-bolt lift kit, providing the matching rear lift height to level the truck's stance.

Fox Performance Series 2.0 IFP Shocks are included at all four corners. These are smooth-body, race-proven monotube shocks featuring an Internal Floating Piston (IFP) design with nitrogen-charged operation for superior heat dissipation and consistent, precise damping response both on- and off-road.

Kit Includes:

• Engine-specific front coil springs (6-inch lift)
• Radius arm drop brackets (caster correction)
• Track bar relocation bracket
• Front compression travel stop relocation brackets
• Steering stabilizer relocation bracket
• Front anti-sway bar extensions
• Drop pitman arm

• Four Fox Performance Series 2.0 IFP shocks (front and rear)

Important Notes: This kit is configured for trucks equipped with the factory 1-7/8-inch rear blocks without top mount overloads. Trucks with 1-7/8-inch blocks and top overloads require additional part #11734. If equipped with factory 3.71-inch blocks or top-mounted overloads, a longer rear u-bolt will be needed. Vehicles with a two-piece rear driveshaft require carrier bearing spacer part #9669.
