Heavy gear or a loaded trailer can make the back of your vehicle sag. The Air Lift 1000 Air Helper Springs add up to 1,000 lbs of load-leveling support inside your rear coil springs, helping you keep a level stance for safer steering and braking. By taking strain off your stock suspension, they reduce squat, maintain headlight aim, and improve handling when you’re hauling a heavy load.
Every trip puts a different weight on your suspension, so being able to adjust pressure matters. These molded polyurethane air springs let you dial in support anywhere between 5 psi and 35 psi to match your load. Inflate each spring independently—with dual air lines if you choose—for side-to-side leveling when cargo isn’t evenly distributed. Manual Schrader valves are included so making adjustments is quick and straightforward.
Heavy loads can cause sway, bounce, and uneven tire wear. By fitting right inside your rear coil springs, the Air Lift 1000 kit absorbs road shock and helps keep the vehicle planted. The result is steadier control on highways and curves with less bottoming out over bumps. Steering feels more predictable, braking stays even, and the ride is smoother no matter what you’re carrying.
Each air spring is made from tough molded polyurethane that stands up to everyday use. The kit comes with two air springs, heat shields, tubing, Schrader valves, and hardware for installation using standard tools. Once set up, you can count on leak-free operation that holds pressure for the long haul. For even more convenience later on, you can add a compressor system (sold separately) to monitor or adjust air pressure from inside the cab.

Hello, neighbor Steven here with etrailer.com. 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 etrailer.com. 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Keep in mind, sometimes this video can be outdated and it could possibly fit newer years as well.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.

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!
