Heavy loads can cause the back of your vehicle to sag and add unnecessary stress to your suspension. This stress not only affects your brakes in a bad way, but your tires, headlight aim and handling suffer as well. To improve your vehicle's ability to endure heavy loads, you need to add support to your existing coil springs.

Air Lift's AirLift 1000 adjustable air springs have 1,000 pounds of load-leveling capacity and are made specifically to fit inside your rear coil spring suspension for additional load assistance. You can inflate and deflate these tough, molded polyurethane helper springs as needed, ensuring the perfect amount of support for every load, every time. Easily level your vehicle front to rear, and if you run dual air lines to the air springs at installation, then you can inflate the springs independently of one another for side-to-side leveling. AirLift 1000 is a breeze to install with standard tools and comes with an easy-to-follow instruction manual.

AirLift 1000 comes with manual inflation valves that are typically mounted on the bumper but can be installed anywhere on your vehicle for easy access. For even more convenience and control, you can add a compressor and gauge system (sold separately), which will let you monitor and automatically inflate your air springs.

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.

Air Lift is positive that you will benefit from their air spring suspension system - so much so that they offer a 60-day satisfaction guarantee. Install and use AirLift 1000 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.

Video Transcript for Review of Air Lift Vehicle Suspension - Rear Axle Suspension Enhancement - AL99PD

Hello, neighbor Steven here with Folks, today we're looking at our Airlift 1000 air helper springs for the rear coil springs. Sorry folks. These are for your rear application. They're also a custom fit application, so I highly, highly recommend you check out our fit guide here at Make sure you're putting in your year, make and model on our homepage where it says my vehicle or something of that nature, enter your make and model, cab, bed length, anything it asks.

Keep in mind, sometimes this video can be outdated and it could possibly fit newer years as well. That being said, let's get into it. This is gonna provide a thousand pounds of load leveling support. So it's not adding a thousand pounds capacity to your vehicle, it is just giving you a thousand pounds of support. You can adjust these between five PSI minimum all the way up to 35 PSI.

They simply get smashed down and wiggled in between your coil springs, and then that's where they're gonna sit once they're installed. All the instructions that come with it, you shouldn't have any problems, should have no drilling whatsoever required to install these. So it should be a pretty simple installation. Now, like I said, these do keep your vehicle level when you're hauling a heavy load. They also improve steering and braking performance, and they help maintain what we call here at etrailer, a headlight aim, a safe, safe headlight aim.

So if you're squatting in the back, your vehicle's gonna be kind of pushing up your headlights up here in the front, but with the air springs in the back, it's gonna push you back level and now your headlights are pointing level instead of up in the sky. Now, you can manually adjust both the left or the right independently if you so choose, but this is set up to do them or as a system tied in together rather at the same time. Now, I do recommend that you possibly maybe want to add a compressor system that would be sold separately. With that, you can monitor and adjust the air pressure from inside the cab or whatnot, but usually with these guys, you're not doing too much adjusting, so you should be okay. Most likely with just the kit you see here.

Has a lifetime warranty by the manufacturer, and they're made right here in America. This is the Airlift 1000 air helper springs for the rear coils. Again, you're getting all the hardware, air hose, everything you see before you included. That's gonna wrap it up, folks. I'm Steven. Thanks for watching.

2021 GMC Acadia

Very difficult to install as you have to push the bag through the coil of the springs. Once you get through that it is not so difficult. You need to make sure the tubing is tight on barb fittings and secured. It hold pressure great and I did notice a big improvement in ride Quality but it didn’t help with the squat after connecting up the trailer, that remained fairly unchanged. These did prevent the “bouncing” of the Acadia caused by the trailer and helped greatly with control.

2020 GMC Acadia

SO FAR every thing has gone well i am having them installed tomorrow and continue to hope all is well



they were installed within a few days of receiving i was told it was tuff to run air lines so they would be out of harms way not sure if that was true as i can not walk bend well enough to check them out but they have worked great i carry a scooter with tray about 450lbs total made a big difference


looks good i will know more when i have them installed


Just install them support and raise very well but of course these aren't really easy to install takes a lot of patience and hand strength

2022 GMC Acadia

Great Deal.....GREAT SERVICE !!!!!!!!!! !!!



I added this kit to my 2005 Chevy Tahoe Z71 last year (2023). This kit was exactly what I needed to compliment my already installed, upgraded Bilstein shocks to help me tow a Camaro on a car hauler trailer from Colorado to Florida. I kept the bags inflated to 30-35psi the entire trip. I experienced no bag leakage, sag, sway, or bounce while towing. After the haul to Florida, I have kept the bags/kit in place with the bags regularly kept at 5-10psi. This has stiffened up the rear end nicely (not too much) as a daily driver hauling kids, sports equipment, tools, etc. without any issues. Intial install took about 2 hours as the most difficult part was feeding each bag through/inside the rear coil springs and making sure of no pinch points on the bags. I would recommend this kit as the materials, instructions and support from etrailer with videos, pics, and reviews (if needed), are top notch! Thank you etrailer!


They work great. I’ve used them to align my boat, a utility trailer and the wheelchair carrier for my wife. Has improved the ride and gas mileage by making the combinations more aero Dynamic. I would purchase again and recommend them to others


Very nice product so far. Installed on a 2011 Toyota Sienna van that has been converted to a rear entry wheelchair van. The airbags allowed for that extra stiffness needed to compensate for the added weight of the wheelchair. Ride quality did not suffer at all, and in fact, felt better with less sway. Hopefully it will last for a long time, but so far, we are very happy with it.


Product arrived promptly. Very simple idea, but absolutely difficult as H&¿¿to install. Trying to squeeze the folded air bag between the coil Springs was an absolute nightmare. Maybe some springs on some vehicles have a larger spacing between the coil,but a 2019 Kia Sorento does not. It took almost 6hrs to install both sides. One trick that did help was to use a little silicone spray on the air bag where it was jammed into the coil spring. This helped make the bag slippery so it passed between the coil spring. Just don't get it all over the air bag or it will be too slippery to hold onto as you push it into place. The hose clamps are really a poor design, awkward to squeeze with pliers as you position them into place. So far bags appear to be holding air pressure. Time will tell has to how durable and dependable they will be.I installed them to assist with towing my camper and help reduce the squatting when towing.


Air lift 1000 installed in my 2016 Toyota sequoia. Installation went smooth and was easy to install. I have the bags set to 15psi now for daily driving. Will monitor it for a a couple weeks and see if there is any leaks.


Installation was a breeze - of course after putting the truck on a frame lift and taking off the tires and wheel wells. Long enough line to run it to the bumper and really easy to fill. Impressive!


2017 Toyota Sienna van, very helpful for heavy loads and load balancing when pulling 13’ fiberglass and 19’ popup campers. Have used these for years on several different vehicles and have never been disappointed.


After a year it's been great. One thing I do remember is definitely have some extra hose clamps on hand. Only provided enough for each hose end and 2 of them were already brittle and snapped when first opened. Other than that no issues. I keep it on 5psi without added tongue weight, 25-30 with the bike or cargo hitch racks. Without it I'd sag a good 4-6 inches and only have about 2 to 3 inches of wheel clearance on my 2023 Pathfinder Rock Creek. With it aired up it only sags maybe an inch.


Great bang for the buck and I had no problems installing myself along with new rear shocks. I had my doubts, but we just completed a 2 week trip fully loaded and towing our popup camper, and they still held 22 psi after all that (started with just under 30 psi so no real leaks!). Definitely improved the ride height and overall handing in all conditions.


Reviewing the Air Lift 1000 kit 60860 for Kia/Hyundai SUV
Installed in a 2017 KIA Sorento LX. Like many other reviews claim, this was not easy to install although the factory video makes it look so, so simple. I followed the instructions for the first bag, it took me 2 and ½ hours to get it inside the spring coil. I used an exacto knife for cutting the hole, which worked very well. Not having a spoon type tire iron, I eventually settled on the handle of a large crescent wrench. After inserting the bag ½ way in, using the wrench to push on the part already in the spring brought the rest of the bag further in. Eventually I finally got the first bag inserted although it was twisted. Inflating the bag straightened it out. Starting on the second bag, I noticed it was much more pliable. It had been sitting in the Florida sun for the past 2 ½ hours. I folded it down as instructed, then folded it in ½ lengthwise and used zip ties to secure it. After sitting in the hot sun for another hour while I hydrated, it only took me 10 minutes to get the 2nd bag inserted and needed no other tools to assist. Carefully snipped the zip ties off and it popped into place. Running the air lines was simple enough. The hose clamps are very fragile, be patient, be careful or they will break.
Overall I am quite pleased with the performance of the bags. They make a big difference in how the KIA rides when towing. They hold pressure and are easy to inflate & deflate. I use a bicycle tire pump as I have no need to modify the pressure in route and didn’t see the need to spend the money on a remote control inflation system.


Very easy to install , the best choice I could have made for towing 16ft 6000lb + trailer . Haven’t had to make additional adjustment since installed over a year ago


Installed this kit on our 08' sienna awd the day before a road trip. Install went fairly smooth. It did take a couple of attempts to get the air bags stuffed into the coil springs. Routed both airlines individually and mounted on lower bumper black trim just above the hitch. Held air at 35psi overnight, deflated to 25psi with cargo and hit the road. All seems well and the van handles better loaded.
Have to echo other positive reviews of this product. Makes the sienna even more versatile, and it is both affordable and a moderate diy project for shadetrees like me


Great price, shipping was fast. Was easy to install. Its great keeps my van nice and level when hauling and definitely a difference in suspension and smoothness.


Package arrived damaged,no parts missing or damaged, can't comment on product not installed at this time.


Getting the tubing completely over the plastic barbed tee fittings is difficult at best without damaging the fittings. The bags will not hold pressure for more than a day. The metal barded fittings are much easier to use & get the tube seated properly. Recommend NOT using the plastic tee fittings.
Getting the bags inside the springs is a test of patience, flexibility, hand & arm strength within a confined area. This is not a quick installation AND make sure you're in the shade because you'll be sweating enough without the help of the sun.
Once everything was installed & inflated, the ride without the trailer was noticeably better & with the trailer, the bag end sag was completely eliminated. FYI, the ride of the KIA without the air bags & trailer is already very nice.


its been a year of using the lift kit on the Jeep Wrangler Rubi (4door). no issues. did replace the clips with tighter fitting clips.

not much else to say. works as advertised.


Have had these for better than a year. With the excessive amount of weight I haul around daily, I've seen vast improvement in overall handling. Also much smoother ride,with alot less tire wear. Not to mention no more dragging of the hitch in and out of approaches. In short I have been overly impressed with this product performance and ease of installation! 5 STARS


These air bags are very difficult to get into the coil spring. You must disconnect the shock absorbers and disconnect the brake line bracket. Also lubricant of some sort was most helpful. Connect the air lines while coil springs are fully extended. Otherwise you'll never get them in. Once they're inside some compressed air is helpful to blow up the bag. Once installed work quite well.


Installation was super quick and easy in my home garage. The hardest part was finding a way to jack the truck high enough to hang the rear axle. My test was 25 bags of mulch. The before installation picture shows the rear squat. The after picture is of the exact same load with 30psi in the air bags. Super happy with the results. The ride is much better with a load in the back. Can't wait to hook up my camper to see how much better the ride is on a long trip.
