"I bought this air system to dampen the spring shock of my already nice riding 2012 GMC 3500 4x4 and it did as expected. The install was very easy with one exception. The right park brake cable bracket was a bit of a problem to tweek and make work but dooable. One of the best installation info I've had in awhile. Thanks so much to Auto Anything for their curtious and promp service." —Michael W A from Vinita, OK bought an Air Lift Air Bag Suspension Kit for a 2012 GMC Sierra.
