Heavy loads can make the back of your vehicle sag and throw off handling, steering, and braking. The Air Lift 1000 Air Helper Springs for coil spring suspensions add up to 1,000 lbs of load-leveling support so you stay level and in control when hauling or towing. They keep your headlights aimed correctly, reduce tire wear, and take strain off your factory suspension so everything feels balanced even under heavy weight.
Every load is different, and these molded polyurethane air springs adjust to match. With a simple fill through Schrader valves, you can dial in air pressure anywhere between 5 psi and 35 psi. Run them at higher pressure when carrying a heavy trailer or bed load, then drop them down for unloaded daily driving. Add dual air lines during install if you want to fine-tune each side independently for uneven loads.
When the road gets rough or the trailer starts to push from behind, these helper springs go to work absorbing bounce and sway. By sitting inside your existing coil springs, they help stabilize the rear end and cut down on porpoising or side-to-side movement. The result is a steadier, more comfortable ride whether you’re towing long distance or just driving around town with gear in back.
This kit installs right inside your rear coil spring suspension using standard tools—ideal for anyone who likes tackling projects in their own driveway. Everything you need comes in the box: two air springs, two heat shields, tubing, Schrader valves, and hardware. You can mount the manual inflation valves on the bumper or any convenient spot for easy access, or add a compressor system later to monitor and adjust air pressure on the go.

Got the airbags especially for towing a trailer 0n a 6 month trip from Arizona to Alaska, 24000 miles.The bags are still performing well.I would give 5 stars for reliability and performance.

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!
