Heavy loads can make the rear end sag and throw off your handling. The Air Lift 1000 Air Helper Springs add up to 1,000 lbs of load-leveling support inside your rear coil springs so your vehicle stays level and stable. That means better steering, braking, and headlight aim when towing or hauling, without bottoming out or squatting under weight.
Every load is different, and this setup lets you dial in the perfect balance. You can manually adjust air pressure from 5 psi to 35 psi to match what you’re carrying. Inflate both springs together for even support or run dual air lines to adjust each one independently for side-to-side leveling when loads are uneven.
These molded polyurethane air springs fit right inside your existing rear coil springs to absorb bumps and road shock. They take stress off your factory suspension and cut down on sway so your ride feels steady and predictable, even when the pavement isn’t.
Installing real load support doesn’t have to be complicated. The kit includes two air springs, heat shields, tubing, Schrader valves, and hardware—everything you need for a clean fit inside the coil springs with no frame drilling required. Add an optional compressor system later if you want on-the-go pressure control, or keep it simple with the included manual inflation valves mounted wherever is most convenient.

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.

Works great during the two times I actually used them. Dont inflate too much or youll hear squeaking sounds that will drive you insane.
