Heavy loads can make the rear sag and throw off braking, steering, and headlight aim. Air Lift 1000 air helper springs add up to 1,000 lbs of load-leveling support right inside your rear coil springs, helping your suspension hold steady under weight. They keep your vehicle level when you’re hauling or towing so handling feels predictable and the ride stays stable mile after mile.
Every load is different, and these air springs adjust to match it. You can manually inflate or deflate them between 5 psi and 35 psi for the exact support you need. Keep them firm when carrying heavy cargo or towing to control squat and sway, then drop them down for a softer ride when unloaded. Run dual air lines if you want to level out uneven side-to-side loads.
Installation is straightforward with standard tools—no exotic gear needed. The molded polyurethane air springs slip right inside your existing rear coil springs, with included tubing, Schrader valves, heat shields, and hardware. Inflation valves can mount on the bumper or wherever access is easiest. Add an optional compressor system later if you like in-cab control and automatic air adjustment.
Built from tough molded polyurethane, these helper springs are made to hold air pressure without leaks and handle real-world load cycles. The design helps reduce tire wear and suspension strain while absorbing road shock for a more stable ride. With proper air pressure set for each haul, your suspension stays healthy and your load feels balanced trip after trip.

Installed quite easily & has performed great! Truck & trailer can now be leveled off in less than 1 minute with 12 vdc air compressor. Truck drives & handles the trailer so much better!

It works better than expected. The headlights no longer point to the treetops when I attach my trailer and my front brakes have more stopping power because the truck is now level at all times.

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.
