When hauling heavy gear or towing, your suspension can start to sag, throwing off your handling and braking. The Air Lift 1000 Air Helper Springs for Coil Springs - Rear add up to 1,000 lbs of load-leveling support inside your existing coil springs. They help your vehicle stay level under load so steering stays controlled, brakes feel consistent, and headlights stay properly aimed. By sharing the work with your factory springs, these air bags reduce tire wear and strain on your stock suspension parts.
A rough or uneven load can make your ride bounce around or lean to one side. With adjustable air pressure from 5 psi to 35 psi, you can fine-tune the support for every trip. Add air when hauling heavy weight or towing and drop the pressure when unloaded for a smoother drive. Each spring can even be inflated separately using dual air lines to level off-center loads. The molded polyurethane air bags absorb road shock and cut down on sway so the ride feels stable and planted on highways or rough roads.
Installing load support doesn’t have to mean tearing into your suspension. This kit fits directly inside your existing rear coil spring suspension using standard tools. It includes two air springs, two heat shields, tubing, Schrader valves, and hardware for manual inflation. The valves can mount through the bumper or another spot that’s easy to reach for quick air adjustments. For more control, you can later add an onboard compressor system (sold separately) to monitor and adjust pressure automatically.
Each air spring is made from durable molded polyurethane that stands up to repeated compression without leaks or cracks. Once installed, you get dependable support trip after trip without extra maintenance. The lifetime warranty and 60-day satisfaction guarantee back up the durability so you can focus on driving instead of worrying about worn-out springs or sagging suspension.

I am glad you found some ways to hopefully prevent this issue going forward. This is definitely something I will pass along to AirLift to take a look at. Besides that I hope they are working well for you when you tow your Airstream. How often are you able to get out and tow it?

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.
