Fabtech K2405M 4-Inch Basic Lift - 2023-2024 F250/F350 4WD 6.7L Diesel - Stealth monotube Shocks

Fabtech K2405M is a 4-inch Basic lift system for 2023-2024 Ford F250 and F350 Super Duty 4WD trucks with the 6.7L V8 diesel engine. Single rear wheel models only; excludes gas engines and vehicles equipped with the Ford onboard scale system.

Package contents

One system includes one FTS22207 front coil-spring box, one FTS22373 Basic component box, one FTS22214 rear block-and-U-bolt box and two FTS6236 front and two FTS6063 rear Stealth monotube shocks. Four new shock absorbers are included.

The spring box contains two new FT30648 4-inch front coil springs; the factory upper rubber isolators are retained. Two FT31079 radius-arm drop brackets retain the factory radius arms.

The Basic box includes one new FT30122 pitman arm with an FT30258 single-use sector-shaft nut, one FT30956 track-bar relocation bracket for the retained factory track bar, the FT3400-112P and FT3400-112D sway-bar drop bracket pair, two FT30653 front bump-stop extensions, two FT30659 front brake-line brackets, one FT31135 rear brake-line bracket, and hardware. The factory steering stabilizer is retained with the FT30672 bracket, FT30686 clevis and FT30604 spacer.

The rear package contains two FTBK41 4-inch blocks and four FT728U U-bolts with hardware. These replace the factory rear blocks; block height does not mean 4 inches of additional rear lift. The factory rubber bump stops are retained with the extensions.

Installation

Installation requires a pitman-arm puller and replacement of the pitman arm using the supplied single-use sector-shaft nut. Follow the manufacturer drag-link installation procedure. Front bump-stop cups/mounts and radius-arm drop mounts require drilling, including 1/2-inch mounting holes and 1-1/4-inch frame access holes.

Professional installation, alignment, headlight adjustment and full steering, brake-hose, ABS-wire, suspension and tire-clearance checks are required. Oversized tires may require fender or valance trimming. Recheck fasteners after 50 miles and periodically thereafter. Follow the complete manufacturer instructions.
