Note: When servicing your truck with Air Lift air springs installed, if the truck is lifted by the frame, the air must be let out of the springs. And if the rear of the truck is lifted during service, then it must be supported by jack stands to avoid damage to the air springs.


Air Lift's LoadLifter 5000 was designed with an exact purpose: to provide full-time, first-class support to your 1/2-ton, 3/4-ton, 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 lbs of load-leveling capacity and distributes the weight of your payload to all 4 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, 2-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.

A couple of minor installation issues but very happy with the product.

Installed as documented. Took a little longer on my truck as I have the rear stabilizer bar, but fit perfectly. I tow a 34 ft fifth wheel and running only 10 pounds of air was all needed to level rear. I used these air lifts on my previous pickup for the same reason and they worked great.

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!

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.


Comments
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.

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.

Review from a similar LoadLifter 5000 in Vehicle Suspension


Exactly what we needed, was originally going to install Air Lift 1000 HD helpers for coil springs. But, those items were on backorder at the factory and that was more of a make do solution. The Air Lift LoadLifter 5000 was in stock, Nicole at etrailer arranged the cancelation of the original order, and had the 5000s shipped. Installation as per the instructions was a breeze, had all the necessary tools until it came time to reinstalling the truck's coil springs. ATTENTION to all, once the LoadLifter 5000 air bags are installed, the axle on a RAM 1500 Classic doesn't drop as far, short by about 2 inches! Luckily, the local store loans tools, with the aid of a coil spring compressor, the coil springs were reinstalled in a few minutes.
Since the trailer electrical connections are on the drivers side of the license plate, I located both schrader valves on the drivers side of the license plate. Note the position of the heat shield on the passenger side.

Review from a similar LoadLifter 5000 in Vehicle Suspension


I have a 2019 Nissan Titan XD with the 5.6 GAS motor. Wanted to do an Airlift suspension to provide a little support and get my headlights perfectly back to level when towing my travel trailer. No one makes an airbag kit for the gas XD, but after discussing it some with John H at etrailer, I decided to go with the kit for the diesel truck and see how things went.
The kit for the diesel truck fit perfectly, except that there is an emissions component hung from a bracket on the driver's sign frame that prevents a direct install of the driver's side bag. My shop was able to install the kit with no trouble - they just had to bend the bracket with the small emissions component attached upwards for clearance. Everything else went in as designed. Great fit - can't wait to see it work under load.


Comments
These things have been great! I tow a travel trailer thats about 8K loaded with roughly 1100 tongue weight. The bags level this load perfectly so headlights are right and everything is stable. I run 10 psi unloaded, 40psi with normal loads in the camper, and 70psi with the fresh water tank full which is forward in the trailer. I kept it simple with individual valves for each bag. Wouldnt change a thing. A bicycle pump is more than adequate for making changes in pressure bc the volume is so low that its easy. All good with this product.

This easily installed on my 2015 GMC Sierra about two, maybe three hours including jacking up and removing from the jack stands.
Purchased this product because I purchased a slide-in camper and wanted the additional support/suspension.
Works exactly as described, cannot find any complaints.

Awesome addition to my truck. First picture shows how much the truck was squatted, the second is after installation and is now level. Ride and drive are so much better. I installed myself with no special tools. Took about 2 hours. Instructions and videos on web site were a big help! Thanks etrailer!

So far I haven't not had any issues with the air bags. I would recommend on the air compressor kits with the self leveling feature though.

Couldn’t be happier! The product shipped on time for a great price. I chose this product because of etrailer’s YouTube video showing a detailed instal on my exact truck. From opening the box to being complete was only 2 hours. Works as advertised and does the trick!

Still works great! I am happy with it. I tow a heavy trailer a few times a year and this works very well. I keep a small bicycle tire pump in the truck and it all works great.

  • Air Helper Spring Suspension Recommendation for 2017 Ford F250 2WD
    The primary purpose of the internal jounce bumpers of the Air Lift # AL88391 LoadLifter Ultimate Air helper springs is to provide a failsafe if the system develops a leak and you lose pressure while you're towing or hauling. This is pretty important, because the factory jounce bumpers are removed to install the air helper springs. If under a heavy load, and the system loses pressure it's possible that the suspension could bottom out which is harmful for the air bags as well as the vehicle. The...

    Though we do not carry the Hellwig product, from what I could find, the SuperSprings # SSA25 kit will install much the same way.

  • Are Spacers Required for Air Lift Air Springs on Lifted 2020 Ford F-250
    If the rear suspension on your 2020 Ford F-250 is lifted, there is a decent chance that some additional spacers will be needed when installing the Air Lift LoadLifter 5000 Air Helper Springs # AL57391 for 2WD or # AL57399 for 4WD. The best way to determine what size space you need though is to actually measure the gap that will be left once the springs are installed.

    According to Firestone, their # F2600 Ride-Rite air helper springs are compatible with DRW models of the 2018 Ford F-350. Per Firestone, in order for the air helper spring kit to fit correctly, the distance between the frame member and the inside of the tire sidewall can't be less than 7-1/2 inches.

    Since you're pulling a 5th wheel trailer, you'll want to go with a air helper spring system that's compatible with an in-bed hitch. The system you'll need will depend on if you have a 2WD or a 4WD truck. The internal jounce bumper feature can be a neat feature to have in the event you have a catastrophic failure of one of the bags, but if that should happen the existing suspension would still provide the necessary support for the short term, so it's not something I'd consider absolutely...

  • Recommended Autosliding 5th Wheel Hitch for 2019 Ford F-250 with 6-3/4 Bed and OEM Puck System
