Heavy loads in the back can make your vehicle sag, throwing off braking and steering. The Air Lift 1000 Air Helper Springs add up to 1,000 lbs of load-leveling support inside your rear coil springs to keep things even. By helping your factory suspension, they stop squat, improve headlight aim, and keep your ride stable when you’re hauling gear or pulling a trailer.
Every load is different, and these molded polyurethane air springs let you dial in the right support. You can inflate them manually anywhere between 5 psi and 35 psi for the perfect balance of comfort and control. Run dual air lines if you want to level off-center loads or T the lines if your weight is even—either way you can fine-tune how your setup feels under load.
There’s no need for major modifications or special tools. Each spring installs right inside your existing rear coil spring suspension using standard hand tools. The kit includes two air springs, two heat shields, tubing, Schrader valves, and hardware so you have what you need to get the job done. Once installed, inflation valves can be mounted on the bumper or another easy-to-reach spot for quick adjustments.
When the road gets rough or crosswinds hit, these helper springs take on the bounce and sway that wear out your suspension. The air-filled design absorbs road shock and helps even out handling so you stay planted and in control whether you’re towing a trailer or carrying a heavy load in back.

Hi, everybody. Andy here with etrailer.com. And today we're gonna take a look at these Air Lift 1000 Air Helper Springs for rear coil springs. Now this is a custom fit part that is designed to fit the 2021 and newer Jeep Grand Cherokee L. To confirm if these will work for your vehicle, take advantage of our vehicle fit guide on our website here at etrailer.com and insert the year, make, and model of your vehicle. And our fit guide will let you know if these or another similar product like these will work for your vehicle.
Hauling or towing heavy loads can cause the back of your Grand Cherokee L to squat and add unnecessary stress to your suspension. This stress not only affects your brakes in a bad way, but your tires and headlight aim and handling suffer as well. So to improve your vehicle's ability to endure heavy loads, you need to add support to your existing coil springs. These springs are made in the USA of a durable, molded polyurethane, and they install inside your vehicle's rear coil spring suspension. They are going to provide 1,000 pounds of load leveling support to improve safety and ride quality on your Grand Cherokee L.
They will support your existing rear coil spring suspension when you're hauling or towing heavier loads, keeping it level, and they will improve steering and breaking performance, help maintain your headlight aim, and they will even reduce tire wear and suspension strain. They are also going to diminish sway and absorb road shock, improving stability and ride quality. Now the air pressure in these springs have a range of five to 35 PSI. You do need to maintain at least five PSI in the springs. You can manually adjust the air pressure to get even load distribution and support that you need.
And with the installation of dual Air Lines, you can inflate each spring independently for side to side leveling of any off center loads. The manual inflation valves are typically mounted on your bumper, so they are easy to reach. Now for even more convenience and control, You can add a compressor and a gauge system. That is sold separately. That's gonna let you monitor and automatically inflate your air springs.
And this kit includes everything that you see here on the table before me. You're gonna get two air springs. You're gonna get two heat shields. You're gonna get Air Line tubing, the Schrader valves, and all of the hardware that you need for a complete installation. Then you're gonna get a, a really good set of instructions here to help you through your installation process and describes, and describe how they operate as well. Now, again, the load leveling capacity is up to a thousand pounds. However, these springs will not increase your vehicle's weight carrying capacity. So you wanna make sure that you do not exceed the manufacturer's recommended weight limit. Well, that's gonna conclude our look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..

The helpers look great on your Hummer, Rob! What kind of travel trailer are you hauling?

I have towed my RV several times over the last year and these helper springs work perfectly! I had a very small air leak but I added some silicone at the airline connections and it is 100 percent! I carry a battery powered air compressor with me and it’s basically a “set it and forget it” systems.

Glad they are working well for you, Scott! I gotta ask, did you do the AHC delete as it was worn our or did you just not particularly like it? I've heard people do this for either reason.

The air springs are still operating as well as the day I installed them. They do not leak any air pressure nor have they degraded in any way. What a great and simple solution that lasts.

Well, after going back and forth - basically it comes down to - 60 day drive warranty doesnt compute. So after spending $300 on install, now Im expected to spend another $300-$400 to have them removed to return them, oh and pay for return. So roughly $800 to get back $130. Ill chalk this up to understanding that if a product doesnt work out in any manner. To remove these, you have to take the rearend of the car off - shocks and springs - then try to get the bags out of a much smaller ending without damaging otherwise youll not refund. Basically no support, other than a were sorry.

Thanks for the great follow-up review, Jimmy! Glad to hear the system made such a noticeable difference in both ride quality and suspension support, even when you’re not towing. It’s also great to hear the install videos helped out along the way. Air connections can definitely be the most finicky part of the install, so we appreciate you mentioning that for others considering the setup. Sounds like the end result was well worth the effort on your Pathfinder. Thanks again for sharing your experience a year later!

The AirLift 1000 isn't designed to provide additional lift over and above factory ride height. It's meant to provide additional support to the rear suspension to eliminate or greatly reduce squat when the suspension is under load from towing or hauling.
