Fabtech K2371M is a 6-inch suspension lift for a 2021 Ford F150 XLT 4WD with the 3.5L V6 gas engine and four-door SuperCrew cab. For gas SuperCrew models only. Excludes Raptor, Tremor, hybrid, Lightning, CCD continuously controlled damping, composite rear leaf springs, Ford onboard scale and BlueCruise configurations. Factory OEM wheels and tires cannot be used.

Package contents

One system includes one FTS22324 Basic component box, one FTS22326 component box and two FTS6266 rear Stealth monotube shocks. Only two new rear shocks are included; the factory front coilover struts are retained and relocated with FT30944 driver and FT30949 passenger lower extensions, four FT20568BK shock brackets and four FT30946 aluminum half bushings. Replacement front shocks and coil springs are not included.

Included parts comprise driver and passenger FT30942 steering knuckles, front FT30644BK and rear FT30673BK crossmembers, differential relocation mounts, skid plate, FT30608 front driveshaft spacer, alignment cams, sway-bar drop brackets, brake-line brackets and hardware. Two FTBK52 5-inch rear blocks replace the factory blocks and use four FT744U U-bolts. Do not stack blocks; the system height is not a claim of 6-inch rear lift.

Installation

Professional installation requires removing the factory rear crossmember and cutting the driver-side rear lower-control-arm frame pocket using the manufacturer template. Factory front strut lower studs are removed, the bushings are pressed out and replaced, and the lower strut end is rotated 90 degrees during relocation. Install the rear shocks with the body down. Follow the complete manufacturer instructions and use the supplied template at its correct scale.

Alignment, headlight adjustment and full steering, brake-hose, ABS-wire, suspension and tire-clearance checks are required. Aftermarket wheel and tire clearance must be verified on the vehicle; trimming may be required. Recheck fasteners after 50 miles and periodically thereafter.

The installed-vehicle photos are illustrative. Their model, cab, trim, accessories, wheels and tires do not establish fitment or package contents for another vehicle.
