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.

Quick shipping and great customer service. Install went very well and has helped reduce the rear sag on our 01 F350 dually. We have a +3200lb Palomino truck camper in the bed. My next project will be replacing stock sway bars with heavier duty sway bars.

1999 Ford F-250 and F-350 Super Duty

Overall I am quite pleased. The install took me about 3 1/2 hours. Now that I know how to do it, I could probably get it done in 2 1/2. The kit comes with an instruction booklet, but the directions aren't the easiest to follow. etrailer has an install video that makes the process much simpler. I installed this kit in conjunction with a B&W gooseneck hitch and they work flawlessly together. I plan to use this truck to tow my 24' gooseneck trailer. It's primary use is on the farm and I haul some heavy loads. I also have installed the Airlift compressor. All together, it makes a nice setup.


After one year they are still working great. Had my 3,000lb plus slide in camper on the pickup for over six months of that time. So far they have been great.


The air bag kit is good for the adjustability in ride. Depending on your load. Only issue was my non standard exhaust by the passenger side bag. I like the fit inside the frame vs the old style I had which sat outside of the frame. Great stability with my fifth wheel being towed. Easy install.


Installed yesterday and working well. Thanks for your help Sunny C!

2003 Ford F-250 Super Duty

Great product Money well spent


The airlift system, kit 57390, was exactly what I wanted. I have a gooseneck hitch in my 2000 F350 and it works perfectly. Easy to install it and am very satisfied with it.


Great product very well built all the parts are of great quality . Airbags and mounts fit perfectly just had to tie back my emergency brake cable out of the way but that's a ford issue not an airbag issue they fill up and hold air very nice pulling my toy hauler thanks for the great production


Kit works as advertised , the instructions could be better , some the steps aren't as clear as they could be .

Not terribly hard to install . Takes about 3 hours to install in the dark


Thank you Brittney for your great customer service. My son is installing the product right now. Returning the incorrect product and you helping with replacement was great. Thank you again.


Great service!!






Review from a similar LoadLifter 5000 in Vehicle Suspension

Installed thes a year ago. I use them to pull my 35 foot fifth wheel camper. They are fantastic I recently added the wireless remote air compressor kit. I really love that!


Review from a similar LoadLifter 5000 in Vehicle Suspension

I installed these on a 2004 Ram 2500. I have towed an 11k fifth wheel approximately 10,000 miles with them and couldn’t be happier. The hardest part was figuring out where to put the airlines. I decided to run them through the existing frame holes and drill out the top license plate screws to give them a stealthy look with easy access to fill. Install didn’t take more than 2 hours with air tools.


Review from a similar LoadLifter 5000 in Vehicle Suspension

This is my second truck I've installed the airlift system on. The installation went smooth, just like before; after watching the installation video it took maybe a couple hours. I had them aired up and hitched the truck to the fifth wheel, and it made a big difference with leveling the hitch load. I'm very pleased with them.


Review from a similar LoadLifter 5000 in Vehicle Suspension

Air Lift Loadmaster kit was fairly easy to install and definitely made a difference! It did take roughly 4-5 hours by myself but that includes prep, ABS and emergency brake relocation, Schrader valve installation and leak check. My only advice would be to give tech tips like a 10mm deepwell socket to remove the jounce bumper on late model Chevrolets/GMC's. I spent 30 minutes trying to figure that one out alone! So far I'm really impressed with the outcome! Thanks!


Review from a similar LoadLifter 5000 in Vehicle Suspension

The installation went smoothly. The only modification I have to make was in the upper mounting bracket. As seen in the photo, I had to relieve the inner edge to clear a motor mount bolt. This did not affect the integrity of the bracket. Had to remove the rubber jounce block on each side, this was not so easy as this is a 1994 Pace Arrow, so the bolts had been rusting for 28 years!! I am checking not for a small air leak but looks like this installation will be successful.


Review from a similar LoadLifter 5000 in Vehicle Suspension

I received these Air Lift Load Lifter 5000 springs just a few days after ordering and all parts were in the box. The instructions were good but the etrailer videos were even better, especially regarding the two bolts being installed on the bottom plate. The instructions were lacking there. I particularly liked the videos of the 2012 pewter colored F 150 and the 2013 silver F 150. Both were 4x4's like my 2014 and had the same suspension.( 2009-2014 are the same). I chose to use two air valves (instead of a T) and placed them on each side of the license plate to distinguish right side from left side and compensate for any potential uneven loads. I have a 34 gallon gas tank mounted on the left side of the frame, so that's a lot of weight when full. One of the videos demonstrates grinding an OE fastener bolt near the axle to gain clearance. We just backed off the bracket then refastened after the install. We thought about running the air lines through rubber hoses for extra protection but we didn't do it this time. I see the premium kits you sell use a braided air line. Nice option but mine was the basic 5000. I was concerned that when the truck is on a hoist lifted under the frame, not the wheels, that the air bags would droop too much with the weight of the axle and perhaps get damaged, but we tried it after airing up the bags, and all seems okay. To remedy that one could always use wheel supported hoists that you drive onto or support the axle with axle jacks. Maybe good to always keep some air in the bags too. I did note that the rear of the truck will rise when air is added in an empty or unloaded truck. About an inch with 20# psi and more lift with more air. Since I have a front level of 1.5 inches over the front struts a little lift in the rear is fine and actually cuts the wind a bit better on the highway. With 20# of PSI empty load the ride is just a bit stiffer or jouncier but I like it. I'm sure there will be less sway with a load. I've yet to pull a trailer or add much weight to the bed but I will at some point and I like the idea I will always have a level stance with air adjustments. I don't like it when a truck points up to the stars! I've been buying from etrailer for many years now and am always happy with the products and service. I like the price match feature and the installation videos are great! Thanks! Happy trails everyone!

Just fine. Holds air consistently and the ride is good.

Review from a similar LoadLifter 5000 in Vehicle Suspension

Air Lift air springs are good and dependable, use them for the last 25 years on three pick-ups always worked great. My complaint would be against the lousy packaging which came with two or three holes and all messed up, luckily all that was missing was one washer.


Review from a similar LoadLifter 5000 in Vehicle Suspension

Purchased the kit to aid in leveling F150 with 3.5 ton trailer. Have a sway bar kit, but needed a little help getting it level. Other options (springs, etc.) were more costly. Kit well packaged, instructions straight forward. Installation was a leisurely 4 hours. Go to have a second set of hands if you can get help. Run T 5 psi around town and 18-22 psi with trailer connected. HUGE improvement for overall performance in handling.

Really good fix for trailer sag.

Product has been outstanding. Have pulled over 5000 miles with it with zero issues. Helped transfer more load to front suspension which adds more confidence in turns and stopping. Makes leveling a breeze.

  • Do Air Lift Air Springs for 2004 Ford F-250 Super Duty Have Specific PSI Inflation for Load
