Question:
I have a 2027 Chevy Silverado 2500 4WD that I use as my daily driver and to tow our travel trailer on weekends. I'd like to add air bags to help with the rear sag when we're towing, but I don't want to have to keep air in them all the time when the truck is unloaded. Are there any air bags that can run with no pressure when I'm not towing?

Hey Daniel, yes there are! For your 2027 Chevy Silverado 2500 4WD, I recommend the Pacbrake Alpha HD Pro Air Helper Springs # PB72XV. These have internal jounce bumpers that allow you to run the air bags at 0 PSI when your truck is unloaded, so you won't have to maintain a minimum air pressure like you would with traditional air bags.
When you're towing your travel trailer, you can inflate the bags to help level your Silverado and reduce rear sag. The internal bumpers also provide additional support if the air pressure drops. I also recommend adding the Pacbrake Bravo Wireless Compressor System # PB65KJ. This lets you adjust the pressure from your smartphone no matter where you go, and save your preferred settings for towing and daily driving.

We're towing a 2025 Grand Design Reflection travel trailer, and I already have a weight distribution hitch. Will these air bags work with that, and can I still let all the air out when I'm driving without the trailer?
