Features to know about

Stay Level and Confident Under Load: Up to 2,000 lbs of Rear Suspension Support

When heavy gear or a trailer pushes your rear suspension down, handling and braking can get sketchy. The Air Lift Ride Control Air Helper Springs add up to 2,000 lbs of load-leveling support to keep your ride height even and steering predictable. With the rear end level, headlight aim stays right where it should be, and you get steadier control whether towing or hauling.

Tuned Support for Every Trip: Adjustable from 5 psi to 100 psi

Every load is different, and this setup lets you dial in exactly what you need. Air pressure adjusts between 5 psi and 100 psi so you can soften things up when unloaded or firm them up when carrying weight. Each air spring can be inflated separately for side-to-side leveling of off-center loads. When you want hands-on control, manual inflation valves mount on the bumper for easy access, or you can add a compressor system later for automatic adjustment.

Smooth Out the Ride: Reduce Sway and Road Shock

Rough roads and uneven loads don’t have to beat up your suspension. These air springs install between the frame and leaf springs to absorb bumps and minimize bounce. They reduce sway, body roll, and porpoising so your truck feels planted even with cargo in the back. That smoother, more stable ride also means less stress on your tires and factory suspension parts.

DIY Friendly Setup That Fits Right

You don’t need a lift or shop tools to get these working. The Ride Control kit includes all mounting brackets, hardware, tubing, alignment tool, and Schrader valves for manual inflation. The included alignment tool centers each spring correctly between the frame and leaf spring to prevent rubbing or wear. Once installed, the system is simple to maintain and built to provide long-term support without leaks or constant adjustment.

Video Transcript for All About the Air Lift Ride Control Air Helper Springs

Hello everybody, this is Jeff at etrailer.com. Today, we're going to take a look at the Air Lift Ride Control Adjustable Air Helper Springs for your rear axle. Now, this is a custom fit part. It is designed to fit the 1992 to 2000 Chevrolet and GMC Suburban and Yukon SUV's and it fits some other vehicles also. But what I would recommend for you to do is on a custom fit part like this, is to go to our website, use our fit guide, putting your year and model vehicle and it'll show if this will work for your application. Now this will provide your vehicle with up to 2000 pounds of load leveling support, reducing the strain on your rear suspension and improving both safety and ride quality.

And it is designed for light to medium duty trucks, vans and SUV's with Leaf Springs. Now this will help keep your vehicle level when you're hauling a heavy load, improves steering and braking performance and it helps to maintain safe headlight aim. Keeps your tires from wearing unevenly and it'll let you manually adjust the air pressure to get even load distribution and support that you need. You can level your vehicle front to rear. Then you can inflate each spring independently, for side to side leveling of off-center loads.

The adjustable air pressure in these Air Springs is 5 PSI to a 100 PSI. Now this reduces the strain on the OEM suspension that can be caused by extremely heavy loads, improves overall stability and ride quality and it'll diminish any sway and absorb any road shock for a nice smooth ride. Now, these do install between your vehicles frame and its Leaf Springs. They do use the manual inflation valves, which are typically mounted on the bumper for easy access. And it does include everything shown here on the table, include the 2 Air Springs, the mounting brackets, the hardware, the tubing, Schrader valves for manual inflation.

In this kit, they even include this alignment tool to help you in installing this. And it does come with a nice set of instructions, that'll describe how all this installs. Now we, you can add a compressor system with in-cab gauges to monitor and automatically adjust the air pressure. We do sell those items separately on our website. These parts are made in the USA.

Specs again, the load leveling capacity is 2000 pounds. Ride Control Springs, these Ride Control Springs will not increase your vehicle's weight carrying capacity. So you want to make sure not to exceed the manufacturer's recommended weight limit. But that should do it for the review on this Air Lift Ride Control Adjustable Air Helper Springs for your rear axle..

Working around the Tahoe fuel tank is a killer of time. I got both sides install. The Tahoe Rear Axle Bumper Brackets front mount bolt is in the same location as the lower rear Air Lift kit mount bolt. Got bolts installed but the installation should warn you to review carefully before drilling the holes for the mounting bracket.
The air fitting take a 1/2 inch wrench. Instructions say 7/16 wrench.

So far so good. Use it about once or twice a month to eliminate squat and increase stability when towing horse trailers. I just use a simple bike pump to inflate. All is good after several long trips and a year.

Glad you like it, Scott! What are you typically towing?

These have been awesome and totally changed my truck. I have a 1st Gen (2000) Tacoma. These have allowed me to load/tow right up to max recommended weight. Before these the truck was scary to drive when it was 1/2 loaded. It is much safer and easier to drive now. I love being able to add air when I need it. Since I already had a lift kit on the truck, the installation required me to fab a small bracket to make things fit, but it wasn't a big deal. Customer support was excellent answering questions.

This kit is exactly what I wanted. The weight of my trailer tongue varies between 150# and 300#, depending on the loading of the trailer. I need the ability to account for the trailer tongue weight. This air lift kit allows me to easily level the truck with air pressure to account for various loads whether in the truck or trailer. PS - ETrailer.com is the place to purchase. They are an excellent business with great support.

Great! Ive used air lift kits on 5 different vehicles. I always purchase the kit specifically recommended for the respective vehicle. I highly recommend them.

Great system installation was not too hard. I drive a Ford E150 van full of tools, and it was sagging in the rear now I'm ridding level again and going over speed bumps without bouncing all over the place. Nice system at a good price.

That is great to hear, and it looks nice on that E150! I am glad its got you back to level, and instead of speed mountains they are back to normal speed bumps without all the movement lol. Did you install yourself?

I was pulling a heavy trailer and wanted the airbags for stabilization and leveling. It worked even better than I expected. Was very easy to install too took less than two hours.
by:
1999 Toyota Tacoma
It was pretty straight forward it took me a bit longer to install but I was being overly cautious. Also a bit hesitant to drill holes in the frame but after installing it, i wasn't to worried about it. My friend ordered the same set up for his toyota and we'll be installing it the week. It helps the ride wether you are hauling or empty. I give it 5 stars on installation and final performance.

I bought these to take the bounce out of the truck when pulling my front end heavy enclosed trailer. Worked fantastic. Kit came with everything needed and only took about 30 minutes to install.

Way to go on the install! Glad these have worked well for you :) would you have any install advice for anyone combing the reviews for helpful tidbits?

by:
Product was as advertised, and the install went smoothly. Toyota Tacomas are infamous for sagging rear ends, and these air springs handle that well. For now I can only comment on installation, as I've yet to load the truck with a heavy trailer. All parts can be mounted comfortably by jacking up the rear axle and removing a wheel. I didn't have any alignment troubles, and the instructions were specific to these parts and my truck. Buyers should be aware that air springs require regular checks to make sure they are inflated to a minimum pressure. I can easily reach in and squeeze the spring to check inflation, and it's faster than pulling out a pressure gage.

Ive now crossed the country several times with a 2,500 lb travel trailer. The air springs leveled the truck well, and no one flashes their high-beams at me anymore after dark. I will concur with the review below that the truck now bottoms out much sooner when empty and with reduced pressure in the springs. That may be normal, but its literally shocking and unexpected.

by:

2024 Chevy Colorado Trail Boss. These Airbags far exceeded my expectations. Installation was straightforward and took less than an hour to install.
I carry a lot of tools and equipment in my bed and these airbags keep my truck level. I put 30 PSI in each bag and haven’t lost any pressure in 2 months since they were installed.
I highly recommend this product. Also awesome Customer service when ordered
by:
great company to work with, they sent me a new air bag when mine had a leak and the shipping was fast. the install was a little difficult, had to drill holes in the frame. i have the silverado 1500 classic 07 so most aftermarket parts need some modifications anyways. i’m now able to haul comfortably without “trailer squat”

2019 F150 FX4 W/suspension level kit. Straight forward install. Easily leveled the truck back out while towing a 24' bay boat with bed loaded down too. recommend for similar applications!
by:
Yeah really good. I haul heavy wet firewood often. 2000lbs is a guess in my Toyota pickup. That weight not possible without these airbags. They get used often. No leaks. Really happy with them. Love carrying a bike pump around and pumping up after weight is on. Instal wasn't too bad as I recall. Has to bring out the grinder for a second or two.

The AirLift system we talked about a couple weeks ago was sent to my daughter, Kristi's house. I installed it yesterday. I'm on the road, which isn't the best place to do the installation. My father in law didn't have any socket wrenches so I started with a couple 9/16 open end wrenches. These don't work for everything. I went to the local hardware store and bought what I needed. The driver side went on much easier. The hardest bolt was the top one requiring the socket wrench to hold the nut inside the frame. I had to feel for the nut since it was hidden next to an existing frame bolt. I was able to simply jack the back of the truck up at the hitch to gain clearance. I didn't have to remove the wheels. The nylon lock nut was fun to tighten. AirLift should have supplied a simple wrench for this. I found a vice grip needle nose plier worked well enough.

Here are three photos. First is passenger side, second tries to show where top nut goes, third is drivers side. I have then filled to 28psi and will check them this morning.

1997 Nissan Leaf
I found needs to be extremely helpful. I have a 1997 Econoline 150 Ford van. It was a conversion van so lots of extra weight. The back leaf springs were obviously struggling as it rode low without a trailer or any significant load. After installing the air springs, and charging them 1/3 of capacity Or 35 PSI, the ride drastically improved. Shortly after installing them I pulled a 24 foot trailer with a medium load on it, and it drastically improved the ride compared to pulling a trailer previously. Highly recommended and cheaper than new high-quality leaf springs.
by:
2015 Chevrolet Colorado
Install these on my 2015 Chevy Colorado. I pull a fairly big travel trailer and although it's no problem pulling it I had noticed that over the last couple of years the rear of the truck was gradually sagging more. The AirLift fixed it right up.
The ride now inspires more confidence and I definitely have more control over the whole rig.
Installation was fairly easy. I'm pretty handy but quite green when it comes to vehicles so I would say it's accessible to anyone with a handy thumb. I even managed to install them without removing the wheels. It took a bit longer and required more up and down with the car jack but since I did it a couple of hours at a time over a couple of days it allowed me to still drive during the installation process.
I'm am a huge fan and would recommend it to anyone.

I purchased and installed this kit on my 2008 Hummer H3 Alpha to assist the rear springs for towing my heavy jet ski trailer, and it preformed flawlessly. Straightforward install, great quality product, and the bags are holding up really well to the abuse I've put them through. I definitely recommend this kit to anyone considering purchasing it for their rig.

2012 Ford F-150
Product arrived in just a couple of days and was very easy to install. Only took an hour. When I filled the system with air I found a leak on the bag itself. Called Rebecca at etrailer and she gave me the number to air lift and she would check with me in a couple of days. I called airlift and had a new bag in two days. Rebecca did email me and ask if everything was ok. Hooked the camper up and tried it out and man did it work great. This was a great buying experience and will soon purchase the on board air compressor from etrailer
by:
Chevrolet Astro
The product is as described. My springs are starting to sag and I wanted to return the ride without replacing the springs. I was able to adjust the ride. This will definitely help when loaded or trailering.
The install was good with the instructions, but note that the hardened steel frame sleeve (2003 GMC Astro) was a bear to drill through and chewed up drill bits. Just a note for your install. Had it on for three days. I'll update review if things change.

  • What is the Minimum PSI of Air Lift Ride Control for a 1992 Chevy Blazer
    Hey Rick, thanks for reaching out! The Air Lift Ride Control Air Helper Springs # AL59518 should never be deflated below 5 psi when not in use. This is simply to keep just enough air in them to help keep the bags from getting pinched if your factory suspension were to bottom out. You're also welcome to use them without any load in your Chevy Blazer if you'd like a little extra support. What do you mainly plan on using them for? I typically recommend adding an air compressor system when...

  • Should I Install Separate Air Fittings for Air Bags on a 1999 Chevy Tahoe?
    The Air Lift Ride Control Air Helper Springs item # AL59518 for your 1999 Chevy Tahoe should definitely be aired up separately. You should install two air fittings to allow you to fill the bags up with a different level of PSI if needed. Filling them up at the same PSI won't allow you to compensate for an uneven load like a heavy slide out on one side of your trailer. Even though the bags are filled up to the same PSI this uneven weight would cause you to be unbalanced. I also recommend...

  • Minimum And Maximum The Bags In The Air Lift Ride Control AL59518 Can Compress And Extend
    Good question, Clay. This is something we get asked every now and then and can be a concern with this style of suspension enhancement. That being said, the air bags (which have a diameter of 5.1") in the Air Lift Ride Control Air Helper Springs # AL59518 will typically extend/compress between 4.5" to 7". However, they can be compressed to a maximum of 3.1" and can extend to a maximum of 7.34". Air Lift uses bands to hold the bags on, hence the max extended measurement being so close to...

  • What is the Correct Air Psi for Air Shocks on a 1995 GMC Yukon
    The correct psi rating for air shocks can vary from manufacturer to manufacturer. Some manufacturers have ratings as low as 50 psi to the max of 150 psi. I have no way of telling what the correct psi for your vehicle. You will have to contact the manufacturer of the air shock to obtain that information. The suspension enhancement systems we carry do not function like air shocks. These systems are not the soul suspension system like shocks, coil springs and leaf springs are on all vehicles....
