From Air Lift, the leader in innovative load support options since 1950, bring you their latest breakthrough – the LoadLifter 5000™ Ultimate Plus 89399 for your F250 or F350 or F450. Boasting several significant upgrades including stainless steel roll plates, stainless steel hardware, and stainless steel braided airlines, these upgrades augment the internal jounce bumper introduced in the Load Lifter 5000 Ultimate.

Why air suspension? Airbags prevent a vast set of complications that arise from driving an under supported truck, van, or SUV. With properly inflated airbags, you can easily adjust load level, preventing uneven tire wear, vehicle squat, and improperly aimed headlights. Dangerous trailer sway and vehicle body roll will be a thing of the past. Air Lift LoadLifter 5000™ Ultimate Plus airbags are meant for some of the toughest towing or hauling projects, and are only available for certain vehicles.

  • Up to 10% increased load capacity when using steel roll plates, compared to the standard capacity LoadLifter 5000™ Ultimate 89399 air springs.
  • Stainless steel hardware lasts longer than less expensive alternatives.
  • Military-grade fittings thread together, creating a leakproof metal-to-metal seal.
  • Stainless steel braided air lines can sustain more damage than conventional air lines.
  • Most 5000 Ultimate Plus kits are bolt-on installation, with no drilling required.
  • Internal jounce bumper protects against airbag failure by providing support.
  • Compatible with most 5th wheel and gooseneck hitches.
  • Air Lift provides a 60 day, no questions asked, money-back guarantee Lifetime Warranty on the kit.

I installed this kit and upgraded compressor on my 2019 F-450 Platinum truck. Installed perfectly with basic hand tool and ease. I mounted the compressor in the back passenger side behind the rear seat to keep the compressor out of the elements. I shrunk sleeved all the wires from the compressor to the battery which helps protect the wires and aids in a cleaner installation. I love the wireless remote and everything works flawlessly. Spend the money and buy the stainless steel platinum kit from Air Lift. The upgraded compressor is much faster and better built imop. I have Firestone air bags on my chevy and I must say having both I would go with Air Lift hands down due to the quality and options they offer over Firestone.

Overall great experience with Customer service prior to placing the order. The lift kit does everything I need it to do and I would recommend these air bags.

The kit was good quality and I only had to shorten two bolts, way easier than stretching them! I spent several hours installing this but my short bed truck had no room underneath and I am really picky on routing and a quality job. I really appreciate the auto compressor to change the pressure to compensate for loaded vs empty.

My trailer is a 44' 5th wheel toy hauler with a 3600# pin weight. My '17 F-350 need a bit of help to keep the headlights aimed appropriately. The kit was of superior quality to ant Firestone RideRite I've used/installed. Very nice fittings, top-grade hardware. Fitment was spot-on. Directions were clear. There is, however a small leak in one of the threaded fittings that attaches to the air spring. I've improved it with some sealing tape, but it's still there. At this point, removing it to exchange it is more hassle than it's worth. I'd recommend this kit to anyone. Would buy again

Installed on my 2018 F350 and really nice quality product. Just did 3500 miles towing our 2018 VanLeigh Vilano 325RL and the airlift performed flawlessly. Will be purchasing the wireless remote air compressor kit for it next!

Super easy install, all parts necessary were included, even had airline options in the kit. I choose to run a single line from comp.,under driver door, to an air valve at the license plate, in case of a comp. failure I can still air both bags. Remote is real convenient and a must have. hit your programmed psi. and your done.

Love the product, easy install. One mistake, I didn't get air compressor and inflate kit. But will order that soon.

Ordered airbags and compressor. All parts and instructions were complete which made for an easy installation. Equipment performs as stated. The best part is dialing in the amount of psi you want and hearing that on-board compressor kick on. The looks of envy are worth every dollar spent.

Not happy. Air bags have been on the truck for less than 3 months. I tow everyday. The air compressor has power before the relay and none after.

Works Great. Fairly easy to install. Ran air lines to back floor board under seat. Using an air pump, can adjust pressure for ride and load. F 350 rides smoother than wife's SUV.

The 3 day shipping can be misleading. I ordered on november 1st and it will not be delivered until the 13. This is happening with 2 separate orders I have with sdtrucksprings. I guess it takes 10 days for processing. They were cheaper than amazon, as long as you don't mind the extra 10 days. Just an fyi on my experience.

This is my third truck to install a Load Lifter system. Kits are very complete and install is easy using the detailed instructions that have step by step pictures. Used the on-board wireless remote compressor system. System is very reliable and makes leveling a heavy load easy! Highly recommend!

Excellent system it is highly recommended i have personally installed 5 of these in my trucks and will be buying more this up coming year. Very easy to install takes about an hour i would recommend using the heavy duty compressor in conjunction with this unit.
