Air Lift's LoadLifter 5000 was designed with an exact purpose: to provide full-time, first-class support to your 3/4- or 1-ton pickup, motor home, or commercial truck. With this kit, you get a safer ride and simultaneously protect your vehicle from the strain that comes with hauling massive loads.


Carrying heavy cargo in your truck bed or trailer puts tremendous stress on your vehicle. Your brakes erode faster, your tires wear unevenly, and handling suffers severely. When towing, you might also experience excessive sway, bottoming out, and even improper and unsafe headlight aim. Fortunately, there is a solution to these problems. By pairing your existing suspension with the LoadLifter 5000, you can seriously beef up your suspension, ensure equal load distribution, and give your vehicle the support it desperately needs. Air Lift's LoadLifter 5000 provides up to 5,000 pounds of load-leveling capacity and distributes the weight of your payload to all four wheels. As a result, the stress on your OEM suspension is significantly reduced.


LoadLifter's air bags are adjustable from 5 to 100 psi for precise support, and they can be inflated independently of one another for front-to-rear and side-to-side leveling. They are made of high-quality, two-ply, fabric-reinforced rubber. Most air bags lose air at the ends, where the bag is enclosed with a steel cap, because the steel can rust and corrode over time, creating small holes. The endcaps on Air Lift air bags are fashioned from corrosion-proof Zytel nylon, a material that is both stronger and lighter than steel, ensuring that the air bags won't lose air. Also, LoadLifter 5000 comes with Air Lift's exclusive roll plates, which both protect your air springs and beef up the load capacity of the springs.


This system installs with the included brackets and hardware. Just mount the springs, inflate them, and ride. To inflate the LoadLifter springs, you just have to pump air in through the inflation valves. A line kit is included with the springs so that you can install the valves (one for each spring) in an easily accessible area - typically they are installed on the bumper. If you want to make the springs even easier to use, you can get a compressor and gauge system (sold separately).


Air Lift kits are designed to keep your vehicle at normal ride height. You can find the normal ride height of your vehicle by unloading it and measuring the distance between the bottom edge of your wheel well and the center of the hub. After you find and record this distance, you can regulate the amount of air that you put into your air springs to maintain normal ride height - even when you are hauling a heavy load. You will need to adjust the air pressure in your air bags according to the size of your load.


Along with a lifetime warranty that has no mileage restrictions, Air Lift offers a 60-day satisfaction guarantee. Just install and use LoadLifter 5000 springs for 60 days, and if you are not satisfied at the end of this time, you can remove them from your vehicle and return them for a full product refund. Now that's confidence.

Purchased for my 2019 Silverado 3500HD. I've not had long-term use of it yet, but based on other reviews I anticipate everything will function well for many miles to come.
One thing I wish was included in the package from the manufacturer was the Air Lift Union Tee #21838 which I ended up purchasing separatly. The included air line is fitted with an air valve at each end, requiring you to fill the springs individually. For my use, I wanted a single shared line so the springs remain equal, especially in the event of a leak. I recommend the Air Line brand fitting as I first tried a knockoff version since it was more quickly available, but the entire 5-pack leaked around the o-rings so I had even more downtime (do it right the first time...).
I also have a B&W gooseneck wheel hitch and the instructions call for drilling into the frame and using the self-tapping screws to mount the top plate. I was able to use the U-bolts over my hitch bracket at the rear of the plate, but still had to drill into the frame for the front due to the hitch brackets being higher than the frame rail. It's an awkward angle without having lift access, but still very doable - just a tight fit drilling next to the fuel tank.
Overall, a great solution to improving towing.

I am not happy with trailer. The box arrived and was all taped up and abused. When I opened the box there was an important part missed. I called and talked to Joanne and she asked me to send pics of the box and I did and have not heard from anyone about the missing part.i hope you will be able to help me get this part issue solved.



by:

Work the air bags Monday thru Friday every week since install.They complement upgraded leaf springs very well! Had no maintenance or problems of any kind.



by:

Excellent material and the installation instructions were very clear and to the point with the best pictures that coincided with the written material. Only took me 2.5 hours from the start of assembling the air bags with the hardware on the workbench to putting away my tools! This is on my '04 dodge 3500 dually that will be handling my new Host Mammoth Slide in Camper that will set at apprx. 5000 lbs.! Beautiful to maintain level truck and to know that the springs are not collapsed and wearing them down prematurely as well as providing a safe handling truck when on the road.



by:

The air springs solved my driveway clearance issues. Set compressor to 100 lbs for an extra 2” of ground clearance and lowered them to 30 lbs after exiting driveway for cruising. Hardest part of installation was drilling 1/2” holes for the upper mounts. Left the rear duals on for the install. Love the rise at 30 lbs. much smoother and more stable on the road. (2014 Winnebago Vista 31KE) Kelly L. was a great help when ordering!



by:

Installation of the Loadlifter 5000 kit went smoothly, no issues at all. One of the best advantages of having this system on my F-150 is the stabilization it provides when towing our camper. I tow a 6,000 lb camper with an 800 lb hitch weight. I use a weight distribution hitch so the truck and camper ride level, as they should. The difference with the Loadlifter system is that it controls the bounce, providing a much more stable and controlled ride. I highly recommend this air spring kit in conjunction with a weight distribution hitch. When you don't need to added support of the air springs, ie no load, just drop the air pressure down to 5 lbs and you don't know they are there.



by:

Installation was straightforward and retained the original suspension while adding the bags. Inflation to level the rig, a 2018 Ram 1500 and a 3 1/2 ton travel trailer, was surprisingly quick. The ride from Southern California to Central Oklahoma was uneventful. The bags handled the load and the road without sway or dip. Very happy with the product.

  • Will the Air Lift Air Bags for a 2018 Ford F-550 Cab and Chassis Work With 3.5" Lift
    The Air Lift LoadLifter 5000 Air Helper Springs part # AL57345 which is a fit for a 2018 Ford F-550 Cab and Chassis would work with a lift installed but you'd need to install a spacer to compensate for this lift. The Lift Spacers part # F2367 would work with the above kit and get you within range.

  • Suspension Enhancement Recommendation for a 2005 Ford F-450 with Snowplow Package
    Adding an air bag kit to your 2005 Ford F-450 will definitely help improve the ride quality whether you are towing your camper or not. The only thing that I'm a little concerned about is the fitment. Since both the Firestone Ride-Rite # F2176 and the Air Lift LoadLifter # AL57345 have brackets that install on the inside of the frame opposite of where 5th wheel base rail brackets install they may not fit together. I have attached a photo of the Ride-Rite system that you can reference. I...

    The Air Lift # AL57345 that you mentioned would be a great choice for you if there is 8 inches of clearance to the inside of the frame members without any interference from the gas tank of other obstruction. Also, the kit requires that there be 9 inches of clearance between the inside of the tire and the outside of the frame member, see figure # 3 in the instructions. Keep in mind that that an air suspension will not change the capacity of your truck. You will still be limited to the...

    I recommend The Air Lift LoadLifter 5000 Air Helper Springs # AL57345.I like the Air Lift air bags over the other air bags that we sell because they're built strong and with a more durable material while still offering a good comfortable ride. We do not offer 7,500 pound air bags and they will not exist for your 2019 Thor Motorhome on a Ford F-550 Chassis. Using 7,500 pound air bags would be overkill and would provide you with a non comfortable ride. The Air Lift LoadLifter 5000 Air Helper...

If you have this tag you will want the Air Lift LoadLifter 5000 Air Helper Springs # AL57345.

This air spring kit will require drilling into the frame and the distance from the outside of the frame to the inside of the tire must be at least 9" in order for it to properly fit.

These air springs offer up to 5,000lbs of load-leveling support, reducing strain on your rear suspension and improving both safety and ride quality.
