Level your 2015–2020 Ford F150 4WD and upgrade its damping with a complete FOX Performance Series 2.0 IFP front coilover and rear shock set. The front coilovers come factory-preset to raise the front approximately 2 inches over stock, while the rear smooth body shocks provide application-specific damping for comfortable road manners and predictable off-road control.
What's Included & Fitment
- Two front coilovers, part number 985-02-015
- Two rear shocks, part number 985-24-029
- Listed application: 2015–2020 Ford F150, 4WD only
- Front coilovers factory-preset for 2 inches of front lift/leveling over stock; this does not indicate a 2-inch rear lift.
Front Coilovers: Adjustable Leveling and IFP Damping
The bolt-on front coilovers use precision impact-extruded aluminum bodies to increase cooling capacity and resist rust. Vehicle-specific upper mounts include composite bushings to isolate noise and vibration. Locking spring-preload rings retain racing coils selected for the application and allow ride-height and preload adjustment.
Designed to level the truck front-to-rear, the coilovers bolt on without modifications for the stated application. The original product information also describes stock and lifted applications that reuse the stock shock. Inside, the internal floating piston (IFP) monotube design separates oil from the high-pressure nitrogen gas chamber to prevent oil aeration and support consistent factory-tuned damping.

Rear Shocks: Control on Pavement and Uneven Trails
The rear Performance Series 2.0 IFP smooth body shocks combine aluminum construction, race-developed high-flow pistons, and application-specific valving. Their internal floating pistons separate shock oil from high-pressure nitrogen to prevent aeration, while the aluminum bodies increase cooling capacity and resist rust. Quiet nitrile rubber bushings allow increased suspension articulation.

Imported Catalog Note
The original individual front-coilover catalog text lists: 2.0 Performance Series Coil-Over IFP, monotube, threaded aluminum, clear anodize, front, Ford Fullsize Truck 2014–2020, 4WD only, each. The complete set is listed here for 2015–2020 F150 4WD; the broader individual-component catalog label does not extend this set's stated fitment.
