Heavy loads can make the rear end sag, hurt handling, and throw off headlight aim. The Air Lift 1000 Air Helper Springs add up to 1,000 lbs of load-leveling support inside your rear coil springs so your ride height stays where it should. They help your suspension carry the load, keeping steering and braking steady while cutting down on squat, sway, and tire wear.
Every trip is different. With these molded polyurethane air springs, you can set the pressure anywhere between 5 psi and 35 psi to match your load. Running light? Keep it soft for a smoother ride. Towing or hauling heavy? Add air for a firmer setup that keeps things level. You can even run dual air lines to inflate each spring separately when you’ve got an off-center load.
Instead of pushing your factory coil springs to their limit, these helpers take on the extra work. By sitting inside the existing coils, they add cushion and stability without increasing your vehicle’s weight-carrying capacity. That means less bottoming out under heavy weight and less stress on your suspension over time.
Installing support shouldn’t mean a full-day project. The Air Lift 1000 kit comes with two air springs, two heat shields, tubing, Schrader valves, and hardware to mount it inside the rear coils using standard tools. Inflation valves are easy to reach on the bumper or wherever you prefer to mount them. If you want in-cab control later on, you can add a compatible compressor system (sold separately) for quick pressure adjustments on the go.

Very happy with these air springs, set the pressure and ride height when I first installed them, and a year later no change in the ride height an zero pressure loss. I haul a trailer at with it at least once a week and they work perfectly.

Glad to hear they are making towing a more comfortable experience, Mark! Cool little camper as well! ^___^ Where did you guys take it?

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!
