Yes, it looks like the Air Lift LoadLifter 5000 Ultimate Plus Kit (Part #89399) is designed to fit 2017-2019 Ford F-250/F-350 4WD pickups and is commonly used on trucks equipped with the Dana M275 rear axle. Based on Air Lift's application data, we do not anticipate any issues with the lower mounting brackets or hardware fitting your 2017 F-250 Crew Cab Diesel. The kit is designed as a vehicle-specific application rather than being tied to a particular rear axle variation.
The 89399 kit provides up to 5,000 lbs. of load-leveling capacity and includes the upgraded Ultimate Plus features such as stainless-steel hardware, stainless roll plates, braided air lines, and the internal jounce bumper for improved ride quality and added protection.
The Air Lift WirelessAir Compressor System (Part #74000) is an excellent companion to this kit and will allow you to adjust air pressure from your smartphone or wireless controller without having to manually fill the air springs.
If you purchase both the 89399 and the 74000, you should have everything needed for a complete air spring and onboard air management system. The only additional items you may want to consider are:

- An in-cab gauge/controller (optional, since the 74000 is wireless)
- A tee fitting or dual-path setup if you want independent left/right air spring adjustment (most customers use the standard setup included with the compressor)
- A fifth-wheel hitch bracket relocation kit only if your truck has a unique aftermarket hitch configuration, although the 89399 is compatible with most side-mounted fifth-wheel hitches.
