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.
This LoadLifter 5000 Ultimate Plus air spring kit has rustproof stainless steel components that offer long-lasting durability. These components are the roll plates, braided air lines, and air spring attachment hardware.
The roll plates protect the air springs from damage 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.
The stainless steel air lines are tougher than nylon airlines and last a lot longer. They offer extra protection against damage caused by sharp edges and flying road debris.
And the air spring attachment hardware provides excellent corrosion resistance.
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 Plus 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 truck air springs that are easier to maintain.
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 Plus 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.
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 Plus 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.
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). Any air line excess must be coiled up and secured out of the way, so it won't get damaged. The air line cannot be cut or trimmed. And the valves 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.
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.

Hi George, Yes Sir I’m still liking this system. Truck handles much nicer
Ease of install, product quality
Nocoastltd - 05/16/2022I've owned 3/4 ton trucks since 1981 and regret buying a light duty truck when I'm hauling and towing. A close call with an overloaded trailer and the State Police forced me to upgrade my suspension. My search started with overload springs and bump stops but the negatives (for me) was everyday ride quality with springs and remaining load sag with bump stops. I considered a weight distribution hitch but I'm pulling different trailers and hauling firewood in the bed.
Everything mentioned above narrowed it down to air springs so a lot of product comparisons were made and questions were asked to truck mechanics and owners. My decision to purchase this kit was because of the braided stainless steel air lines. Their threaded connection eliminates air leaks and they're much more durable than thin plastic lines when I'm in the woods cutting firewood.
These Air Lift bags were installed on a 2011 Silverado 1500 with the help of a friend and his high lift and it took us about 2 1/2 hours. There's a front leveling kit in this truck and with the air bag pressure at 8 lbs., the hitch level rose 3/4 inch and the ride quality (when empty) is the same as before. When I pulled an 8' x 16' enclosed trailer and 1000 motorcycle last week, the air bags pressure was increased to 30 lbs. and it pulled perfectly. The truck was very smooth at speeds up to 80 mph and there's no sway in the turns at all.
My negatives are:
: Without an electric air pump, it's kind of a pain to add air manually. A small (2 gal.) portable tank that I can fit under the back seat will solve that.
: The mounting hardware in this kit was not stainless steel.
: etrailer does not have a "T" connector for these air lines. They sent two different fittings - one was part #AL21838 for plastic lines and the second fitting (from Air Lift) only had one threaded connector. After waiting 9 days for the second fitting, I found a brass fitting locally for $4.
Received my Air Lift kit in good condition yesterday. Jamie was very knowledgeable and helpful on the phone. The box showed up at y door in two days as promised. I will review the product after I get it installed.
Worked like a charm. Bit of a challenge to install yourself but it’s doable with some patience. I ordered these on [other onince vendor] and one of them exploded on me. The seller had a bogus website and phone number for support so I couldn’t reach them to get it resolved. Ripped it out and shipped it back to [online vendor] to deal with. I will only be buying my truck and trailer stuff from here moving forward.
It is awesome

If you tow frequently this is a great product. For infrequent towers you will find the ride way too stiff even at the lowest setting of five pounds. If there is a product that will allow the factory ride with assist when you need it that would be ideal. I removed the airlift boots after seven months because every little bump was a hard jolt to my passengers. I still have the air pump installed though just in case I become a frequent tower. Hope this helps.

Excellent airbags . I installed these on my 2017 F250 . Driving with no load or trailer with the airbags at 9 psi the truck has a firmer ride on the rear suspension . I'm towing a 13,000 pound fifth wheel . I filled the airbags to 25psi and the rig is level and rides firm with no bounce from the rear suspension . Installation was easy , I drilled the holes for the schrader valves on the bottom corners of the bumper so they are not seen . Highly recommend these airbags .

Before installing the Air Lift 5000 system on my truck it would squat when pulling my camper. Now I can level it off and it helps the control. I installed it and it was not to hard at all!

i originally ordered the Air Lift LoadLifter 5000 Air Helper Springs - Rear Axle
Item # AL57391. This went on back order for one part. (What part I don’t know) but you had the Air Lift LoadLifter 5000 Ultimate Plus Air Springs w/ Internal Bumpers - Stainless Steel - Rear Axle
Item # AL89399. The only difference is the internal jounce bumpers. I feel like I was forced to pay another $XXX for internal joiner bumpers and stainless lines. I think the bags you had in stock are worth it. Didn’t want to pay the price for the more expensive pair but had an upcoming commitment. The installation went smoothly. I had the same type of bags from etrailer on my 2016 F250 that were much more difficult to install. etrailer has definitely refined the air bag system and it’s installation. I installed them in three hours by myself. Follow the directions. The directions however could use some better pictures of how the top plates should look prior to placing them over the leaf springs. The top plate has a bend that was hard to see in the pictures. The bend is supposed to be forward facing the front of h e truck. Hard to see in the picture. I didn’t have confidence in the bag being level before tightening up the square u-bolt. So I left it loose until raised the axle up to bring the top plate in contact with the bag to tighten up the carriage bolts. Over all this was an install someone with some wrench experience. I filled them with 35 psi and let them sit overnight. I’ll update this review when I check for leaks.

Love it!! Convenience of on-board wireless compressor is great, and it keeps the truck level when hauling the 5th wheel. No issues with it. The truck no longer sags in the back with the weight of the 5th wheel.

This system is so good that it effectively allows you to easily tow at or below your maximum tongue weight towing capacity while leveling, improving suspension and ride quality. I had a professional installation which goes against a majority of my diy intuition but I'm very happy I did. They were able to obtain all threaded connections and place manual inflation access on a custom bracket at the rear bumper. They knew all of the line placement issues, how far to safely keep air lines away from heat sources such as the exhaust. I added the AirLift auto sensing wireless controlled compressor unit which has increased livability 100%. You could line check manually each use and multiple times when towing more than 100 miles but for the number of times I had differing L to R pressures buy a few PSI when hauling, which would undoubtedly be worse off if left unchecked for longer amounts of time, it's much more sensible to have a unit that can individually inflate each side of the airbag system independently. This greatly improved safety and efficiency. This may not increase a vehicles tow capacity but it allows the vehicle to tow within designed capacity limits at 100% effectiveness regardless of weight. I am thoroughly impressed and highly recommend this system as the best on the market at the time I purchased it. If anyone knows automotive well, any and every piece of an installation that can be made from anti-corrosion metals ama materials is a no-brainer that will quickly pay for itself. All anti-corrosive parts are particularly useful on the salt and grime exposed underside of a vehicle. The compressor in reference was the EZ75000 model variants.

Install was straight forward. One clip that was meant to refasten the wiring harness didn't really work out but the harness was easily held with a couple zip ties. Otherwise, instructions were clear and all the parts looked good and nothing was missing.

First, etrailer's shipping is amazing. I can't believe how quickly it was shipped and arrived.
I have leveling spacers on the front end of my Ram 2500. The spacers make the truck look great when unloaded, but ridiculous when loaded. These AirLifts really complete the whole truck and level it out even when loaded with a heavy trailer. I keep them under pressure all the time and have zero complaints about ride quality; the truck has always had a rough ride since new when unloaded. It's a truck, not a Bentley. They also stand up well against rough roads.
A few comments on the install:
- When the instructions say "don't overtighten the stainless air hoses" what they really mean is "crank them as hard as you can with a hand wrench otherwise they'll leak". I initially had leaks at the joints because I was trying to baby the threads.
- Why don't the instructions recommend to remove your wheels? You already have it up on jacks. I can't imagine trying to install these with wheels and tires in the way.
- Not all parts are stainless, but I figure that the truck will rust out before these do.

I tow a 5th wheel trailer with a 2017 F250. I would definitely recommend these to anyone pulling near towing capacity. So much added stability.
Review from a similar LoadLifter 5000 Ultimate Plus in Vehicle Suspension
Installed these on my 2019 F-350 SRW after having a local outfitter replace the stock long before with a 9’ CM Truck bed flatbed. I designed the flatbed to incorporate ramps so I could haul my RZR 1000 XP and still pull a camp trailer with the truck. These airbags vastly improved the ride when not hauling, and leveled the truck when loaded. Awesome product! The only gripe is the stainless air hoses were too short to reach where I wanted to mount the schrader valves due to the longer bed. I ended up mounting them to just above the rear wheels. No air leakage, and installed them
myself in about 4 hours. Can’t believe how well the truck rides, even with no load. Highly recommended these!
Review from a similar LoadLifter 5000 Ultimate Plus in Vehicle Suspension
Packaging was amateur at best, multiple parts all scratched up, will need to be bead blasted and repainted to make it right, box had multiple holes and tears, no extra packing inside box, parts literally just thrown in. Pretty disappointed at this price point, I even got the ultimate plus kit, wow is all I can really say, pretty hard to believe
Review from a similar LoadLifter 5000 Ultimate Plus in Vehicle Suspension
Unfortunately I wasn’t able to finish the installation because the 3/8x10” carriage bolts were to short. Now I have to find a store that carries them. Your standard Home Depot, Lowe’s and all hardware stores around my town don’t carry anything that long. I also specified that my truck was lifted and the rear blocks stock on a 2015 f350 had 3” blocks and with the lift it now had 5” blocks. So hopefully I can find bolts that are 12” long before next weekend or we will probably have to cancel our weekend getaway.

This product has made my towing a breeze. My truck rides level and all 4 trailer tires are working in tandem.

the service for delivery is ok but the quality for you product is inaceptable, because I installed the the bag on my truck and both side of the truck the bag don't hold the air I check the installation and evrething looks ok

The only issue I experienced was the nuts to the airbag towers became loose and actually lost one. I picked up self-locking nuts and double nutted them.
