    • Level your vehicle front to back and help maintain safe headlight aim
    • Adjust independently for side-to-side leveling of off-center loads
    • Improve steering and braking performance
  • Jounce spring inside each air spring helps to improve ride comfort, reduce sway, and help with cornering
    • Engages at lower air pressures to better absorb road shock and minimize bottoming out
    • Provides support progressively - the more you load the springs, the stiffer they become
    • Lets you temporarily carry a load with zero air pressure in your springs
  • Quality construction for long-lasting spring life
    • 2-Ply, fabric-reinforced rubber air springs are durable
    • Air Lift's exclusive upper and lower roll plates protect air springs from damage, extending the life of the suspension system

  • Mounting brackets and hardware are included for installation
  • Manual inflation valves and air lines are included
    • Manual valves are typically mounted on bumper for easy access
    • Compressor system with in-cab gauges (sold separately) can be added to monitor and automatically adjust air pressure
  • Made in the USA


Specs:

  • Load-leveling capacity: up to 5,000 lbs
    • LoadLifter 5000 Ultimate springs will not increase your vehicle's weight-carrying capacity. Do not exceed the manufacturer's recommended weight limit.
  • Adjustable air pressure: 5 psi - 100 psi
  • Lifetime warranty
  • 60-Day satisfaction guarantee


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.


Get the Best of Both Springs

The air springs and jounce springs in this system work together to give you the best ride whether your truck is loaded or unloaded. Air Lift's LoadLifter 5000 Ultimate air springs have internal urethane foam jounces that protect the air springs and provide added ride comfort when your air pressure is low. The jounces also allow you to temporarily carry a load if the air springs lose air pressure. This gives your 1/2-ton, 3/4-ton, or 1-ton pickup, motor home, or commercial truck air springs that are easier to maintain.


Air Springs Level Your Load

Carrying heavy cargo in your truck bed or trailer puts extra stress on your truck. Your brakes erode faster, your tires wear unevenly, and handling suffers severely. When towing, you might also experience excessive sway, bottoming out, and even inaccurate and unsafe headlight aim.


By pairing your existing suspension with LoadLifter 5000 Ultimate air springs, you can seriously beef up your suspension, ensure equal load distribution, and get the support you need. The springs provide up to 5,000 lbs of load-leveling capacity (depending on the weight-carrying capacity of your vehicle) and distribute the weight of your payload to all 4 wheels. As a result, the stress on your factory suspension is significantly reduced. LoadLifter's air bags are adjustable from 5 to 100 psi for precise support, and they can be inflated equally for front-to-back leveling or independently of one another for side-to-side leveling.


The air springs are made of high-quality, 2-ply, fabric-reinforced rubber. Most air bags lose air at the ends where the bag is enclosed with steel caps. These caps can rust and corrode over time, creating small holes. But 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.


Roll plates on Air Lift 5000 Ultimate air spring

The air bags also have Air Lift's exclusive roll plates, which protect the air springs and beef up their load capacity. These sturdy plates help guard the springs from moving parts under your vehicle that might puncture the air bags. The plates also provide a larger surface area for each spring to roll on. The extra surface area gives you a higher spring rate at a lower air pressure, resulting in a better ride.


Built-In Jounce Springs Add Control and Comfort

Air Lift 5000 Ultimate air spring with jounce spring inside

The closed-cell urethane jounce spring inside each air spring gives you a more stable, comfortable ride. Each jounce acts as an overload spring and engages when your current air pressure level isn't enough to support your load. So on a rough road, the springs will kick in if needed to absorb bumps and shocks and help you to avoid bottoming out. When the jounces support a load, they adjust progressively - the more weight you pile on, the stiffer they become. The urethane material engages more smoothly than rubber jounces so you get a less jerky ride.


Because these jounces are taller than your factory jounce bumpers, they engage sooner than your factory jounces would to provide better support. And if the LoadLifter 5000 Ultimate air springs have insufficient or zero air pressure, the internal jounces will help to temporarily support your suspension and protect it from damage until you can repair or adjust the air spring system.


Easy Installation

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 in air through the inflation valves. A line kit is included with the springs so that you can install the manual inflation valves (one for each spring). These are typically mounted on the bumper but can be installed anywhere that is easily accessible. If you want to make the springs even easier to use, you can get a compressor and gauge system (sold separately) that allows you to monitor and adjust the springs from the cab of your truck.


Lifetime Warranty

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

Review from a similar LoadLifter 5000 Ultimate in Vehicle Suspension


They were easy for any handy guy to install . It took about 2 hrs. They lifted my 2500 ram to sit level with my 37ft. 5th wheel. I even leave them as is, when I'm not hooked up, and don't notice a difference. I ran two separate lines to near my rear license plate, no compressor. I'm glad I didn't spend that extra money. You rarely change the pressure, and it's so easy to do.


Comments
Im very happy with the air bags. I rv full time, so I tow a 14,000lb 5th wheel. The bags keep my 34ton truck level. The bags dont have much if any effect on the ride. Id buy them again

Review from a similar LoadLifter 5000 Ultimate in Vehicle Suspension


This was installed on a 2021 Chevy Express 2500 van conversion by Explorer Conversion Vans. Explorer installed an Eaton rear suspension and it was not up to the task of a heavy conversion van. I think the air bags help but I will need to upgrade the shock absorbers to eliminate some of the bounce from the air bags. There were three primary issues with the installation:

1) The parking brake cable bracket is in the way and has to be cut off the axle. I attached the parking brake cable clamp to one of the Air Lift bolts using a nut. This is not something every at-home installer can do.
2) The air hose is barely long enough. I specifically asked how long the hose is because I wanted to route it where the future compressor will go and was told there is enough to go around the entire vehicle. That is incorrect. I will have to replace the hoses at my cost when I upgrade to the onboard compressor system.
3) The etrailer video says to drill the mounting holes to 5/16" diameter. The 3/8"-16 bolts immediately stripped out. I should have drilled the holes to 9/32" diameter.

I have bought a lot from etrailer and I will purchase from them again. Most of my issues stem from the poor design and instructions of the Air Lift product. For example, it doesn’t say anywhere on the box or product literature how much air hose is provided.


Comments
Thank you for your feedback. I reached out to Airlift and found that the kit will come with 16 feet of airline hose. If an additional compressor system is purchased then an additional 20 feet will come with it depending on the kit. In the manual there are instructions on how to route the brake lines for non disc and disc brake systems.

The air bags do their job well and would be great for someone who caries the same load all the time or doesn't carry a load often these would be great. I have different loads on my trailer or I'm empty multiple times per day, I definitely recommend buying the setup with an air compressor and remote.


Comments
Im amazed that they havent popped. I definitely put these air bad through more torture than they were intended for. It does seem like they dont lift as well after a few years.

Review from a similar LoadLifter 5000 Ultimate in Vehicle Suspension


This 88205 kit was installed into a 2010 Roadtrek 210P (Chevy express 3500 chassis). If you own one, you know these vans run overloaded even on a good day. This kit was installed to increase stability and to reduce the "crash" as the van goes over bumps. These vans ride on the overload spring and there is no real progression to the rear suspension. The airbags will help absorb some of the impact from bumps in a progressive manner. I will also be installing new front coil springs to bring the ride height back to factory spec. The rear height has come up about an inch (25 psi in the bags) - as you can see in the van picture, there's a rake to the van. This will be resolved when the new coil springs are installed to raise the front height by a couple of inches. I will leave the front Sumo Springs jounce bumpers (black=medium) in place with the new coils. I mention all this in particular for 210 owners - you need to address both front and rear suspension issues.

First, the results. I was anticipating an improvement in driveability but I was very surprised at the huge improvement. Test drive was with 25 psi in the bags - I'll test other pressures to see what they result in. There is much less lean on turns and the rear suspension feels resistant to making every bump a big event. The bags absorb the initial shock and improve ride quality significantly, a lot of the cringe factor is now gone. Much more pleasurable to drive.

The internal jounce bumpers are worth the extra cost - not only do they help reduce the shock of bumps, but they supplement the response of the rear suspension. By this I mean that the airbag will initially take the impact, then for larger bumps, the internal jounce bumpers will progressively absorb more impact. At the same time the rear springs are able to work better since they are not completely dependent on the thick overload spring. Additionally, if an airbag loses air completely, the vehicle can still ride on the internal jounce bumper until repairs can be made.

I installed the fill valves below the rear bumper lip (they point downwards). A bit clunky to get to, but I plan a later install of an on-board compressor. The amount of air line was just enough to run to the back bumper, you need to plan carefully on routing to ensure you have enough line. I did not combine the lines, each bag is filled individually. In my case, due to location of spare tire, water/sewer tanks, fuel tank and coach storage I wanted to be able to tweak each side to get to level ground to fender lip measurement on each side. Gives me a level vehicle even with varied load locations.

I think this is a better kit for our application than the Firestone air bag kit as this kit places the airbag right between the frame and the axle, the best place for load bearing. The Firestone kit places the top bag mount on a bracket mounted to the side of the frame. This can weaken over time with the bracket always trying to resist being pushed off the frame. The Air Lift kit doesn't need any connection to the leaf spring u-bolts and I like that too.

The kit included everything I needed. One of the few times I've not had to change something in order to do a complete thorough installation. Instructions were fine and I liked the torque numbers given - sure you can get the bolts "tight enough" but it's good when a mfg provides complete data. I used the heat sleeve and shield too, the shield is a good idea.

Before final install of the airbag assembly, check the angle of the horizontal bar that extends to the rear from the top bag mount bracket. It's a bit off from the bend in the frame, just needs a check and possible tweaking of the bar. Easy to do, and this will let the top bag mount bracket bear directly on the frame as it's designed to do. The lower bag mount bracket installs easily, and I used the relocating bolt/spacer for the passenger side hand brake cable. Nice to have that detail covered.

On 210's you may have a 1.5 in spacer under the leaf spring - installed by Roadtrek. It will probably have a ledge extension for the frame bumper. You'll be removing the frame bumper anyway, and the ledge extension needs to be cut off to provide space for the airbag. I removed the spacer, cut off the extension and re-installed the spacer. I replaced the original crusty u-bolts at the same time - you should not re-use u-bolts, especially these high torque bolts. U-bolts stretch and also distort at the threads. Get new u-bolts and check them for a few hundred miles after they are installed as they may stretch a bit more. U-bolts are square bend, 2 9/16in. inside dimension to get over 2 1/2in. spring width. Originals were about 11 3/4in long but you can knock an inch off the length. I used oem length and you can see they are a bit long.

I like cost-effective results - this kit provided those results in our case. You always hope for the best and I think that it's of particular benefit to our tubby 210s with that substantial rear weight and overhang. Took me a couple of days to get everything done, but it's well worth the time and cost. Highly recommended.

Review from a similar LoadLifter 5000 Ultimate in Vehicle Suspension


Good product. A slight change from the Firestone double convoluted airbags that originally came with my Chevy p30 Itasca motorhome. But after a few hours of getting them into position properly, the ride is extra smooth. I run these at 100psi and they may only have a slow drop to 98 or 97 psi after a few days. Instructions for the 90 degree elbow say hand tight and then 1 and half more turns, but my passenger side bag, leaked immediately. Pulled the bag back out and reset the elbow with teflon tape and gave it a few more turns. Checked with soapy water, and everything worked perfectly. Depending on the position of your axle, you may have to set the bag a few times adjusting the mounting plate for best fit. The printed template unfortunately didn't help in this 3d space. Best to get as close to upright as you can when you find the correct mounting position.

etrailer was able to deliver these in 2-3 days and had them shipped the day of order.

Review from a similar LoadLifter 5000 Ultimate in Vehicle Suspension


The package arrived all beat to heck but everything was still inside. The installation was fairly straight forward except the instructions had me leave the airbag loose in the mount until the mounts were firmly bolted in place on the frame and spring,this would have been ok but there was no room to get a wrench in the top and bottom to tighten it up. I had to use the by guess method to get them aligned and tightened down then sliding them into place to attach the mounts. I'm a handy guy and the installation on my motor home took about 4 hours, they did the job and brought it back up to level. Will see how the handling is on my next trip.


Comments
Well after a year and several long trips I can say these were a great investment, took most of the seat out of the motor home and helped in windy conditions. I would highly recommend them to anyone!

Lower bracket is not strong enough. Collapsed on the first trip. A replacement was sent out but did not last. I had to fabricate a support under the center of the bracket to prevent bending.

These bags are amazing. Make the rear end ride pretty rough so I put deaver add a packs from carli and did the day star buckets for the bags. Now they are connected when I need them, and disconnected when I dont. Pretty awesome set up. I've put 5200 pounds of rock in the bed of my truck, the rock yard thought I was crazy but then I aired up the bags. You should of seen their faces. Rode level, sat at about 85 psi and rode like a caddy.

The shipping was super fast, only thing I had an issue with was there was no air fitting in the kit which I’m pretty sure they were supposed to be in the kit. I went to my local Napa and got something that should work.

After talking with etrailer they ended up sending me the right fittings which I’m super thankful for, made for an easy install. Still are working like they were the day I installed them. Very awesome product and would highly recommend using their product.

Review from a similar LoadLifter 5000 Ultimate in Vehicle Suspension


We have had the Loadlifter 5000 on our 2017 F-150 for a year now pulling our 6000 llbs of trailer & boat. Not only does it level the truck, but that leveling dramatically improves handling, steering & breaking. We feel much more comfortable on highways and backroads. This is game changing when pulling larger loads in the upper end of of your tow range. Installation on the F-150 was a little more difficult then other models shown, but my wife and I were able to do it in our driveway on a Saturday afternoon.

The Loadlifter 5000 are great, these were recommended by George J. because they have the internal jounce bumpers. As little as 12 psi inflates it enough to get the lift I need for my Nissan Titan XD to stand up level when connected to the Jayco Eagle 5th wheel that I tow.

Review from a similar LoadLifter 5000 Ultimate in Vehicle Suspension


The airbags work great! I can't say enough about how they level out the ride. I have a 32'trailer with an 800lb tongue weight. I put 75lbs of air into the bags and it sits completely level. The ride is excellent. Probably the single biggest improvement you can make. I will say that I had a few issues though. I was originally sent the wrong air line connections for my truck. I received the straight connections and should have had the 90 degree elbows. Replacements were sent out, but I was halfway through the installation when I discovered it which made things difficult. It was sent that way from the manufacturer and was rectified. In my case, getting these elbows installed correctly was a little problematic. They have to fit just right to clear the brackets and it took numerous tries and a little trimming here and there to get them in. Other than that everything went together fairly easily. I also purchased the optional air line tee which makes filling the bags easier and it is something I would highly recommend. Overall very satisfied and would definitely purchase them again.

Review from a similar LoadLifter 5000 Ultimate in Vehicle Suspension


Appears to be an extremely well made product. The instructions are much better than most and even include color pictures. There are also several instructional videos available. However, I did find a couple flaws in the kit. On the driver side, one of the bolts to attach the lower bracket to the axle rubs against the ABS brake wire. On the passenger side: the odd shaped axle strap doesn't fit as nicely as advertised and I had to message the brake line mounting strap out of the way slightly. There is also an issue with the exhaust being really close to the airbag and airline. The kit provides one heat shield to protect the airbag but there isn't anything to protect the airline from the exhaust heat and the exhaust pipe is only about an inch away from where the airline attaches to the top of the airbag. I wrapped my exhaust pipe and the airline in heat tape, but time will tell if that will be enough. Also, my truck is 100% stock so the issues are not due to prior modifications.


Comments
For the ABS brake wire, I would use a zip tie to maneuver it out of the way of that bolt you mention. My contact at Airlift assured me that the heat shield will protect the air bags and air lines within 1 inch of the exhaust. I would route the air line as far as possible away, securing with zip ties.
