Heavy loads can make the back of your vehicle sag, throwing off your handling and braking. The Air Lift 1000 Air Helper Springs for Coil Springs add up to 1,000 lbs of load-leveling support to keep things even when you’re towing or hauling. By helping your stock coil springs carry the extra weight, they keep your ride height level so steering stays sharp, braking stays consistent, and headlights stay aimed on the road where they should.
Every load is different, and this system lets you dial in support with adjustable air pressure between 5 psi and 35 psi. Inflate each spring independently for side-to-side leveling when your load isn’t even. Whether you’re towing a trailer or carrying gear in the back, you can balance the ride for comfort and control. Adding an optional compressor system makes monitoring and adjustments even easier down the road.
These tough molded polyurethane springs fit inside your existing rear coil springs to absorb shock and cut down on sway. They help stabilize the vehicle through bumps, corners, and uneven roads so it feels more planted when loaded. The added support also helps reduce strain on your tires and factory suspension, improving overall stability without changing normal ride height when unloaded.
Installation is straightforward using common tools. The kit includes two air springs, two heat shields, tubing, Schrader valves, and all necessary hardware. Once installed, they’re easy to inflate manually from a bumper-mounted valve or another convenient spot you choose. With durable construction designed to resist leaks and a lifetime warranty backing it up, you get reliable performance trip after trip.

I am sorry to hear these gave you such trouble during installation! If you remove the valve cap on the springs, then you can kneel on it to deflate it and then replace the cap to keep it deflated which will make it easier to install them.

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!

It is annoying to need to keep airing up the springs. I wanted to see if you have used the soapy water test to locate where they are leaking from. If you take a spray bottle with soapy water and spray the lines and fittings on the springs it will bubble where the leak is. It is possible that you will need to recut the line to make as perfect cut as can be using a part like # AL10530. Or if it is a fitting you would need to reinstall or replace it. We do carry replacement fittings and so if one is needed just let us know.
