Yesterday I installed the PacBrake air bags on my Dodge 3500. It was an easy install without even jacking the truck up. Mine is high enough to roll under on a creeper. The kit is very well made and easy to install. Instructions were well written and photo's were great. I installed it with individual airlines so I can control each one separately. I have an on board compressor and in the future I may hook up in cab controls for the system. I have no affiliation with PacBrake and get no reward from them, I just wanted to report what it was like to install and the quality of the system. The lifetime warranty is impressive too.
