rear air bags
 

I'm looking to buy some sort of air bag for my lowered 1500 2009 silverado crew cab I have a flip kit on the rear so I need something that will work with the rear springs under the rear end. Not looking to spend a arm and a leg for rear bags. I don't need a compressor

mcg makes a bolt on kit i believe and slam air has a kit to..i run the slam air on my truck and its lowered 7-8 inches in the rear

Think I spent like $300ish on my setup for my 05. Only thing I would recommend is to change out all the push lock fittings in the kit for compression fittings. Less chance of leakage. This is the kit I got and have had zero issues. Chevrolet Silverado 1500 W/Flip Kit 1999-2006 Rear Air Bag Helper Kit - McGaughys Part# 33024 - Mcgaughys-Suspension.com I would assume their kit for the 07-13 is similar in quality.

The Airlift Slam Air should work also. They can make the rear ride a little better. Putting more than 10psi on them will start to raise your truck.
