Air Lift is the leader in on board air control systems. This is their dual path analog control system that comes complete with a standard duty compressor and single gauge control panel.
Dual path control will provide the ability to control two air springs individually and inflate the air bags separately to stabilize an uneven load (side to side). This is also a good option to control a pair of air springs in the rear with a pair in the front as well.
This system also comes with a low pressure sensor that will automatically activate the air compressor if the spring pressure falls below the safe level.

Purchased this kit after lots of debating over if this kit is what I need for leveling out my truck. The air bag kit and analog air compressor kit is just what I needed. The best thing is the analog air compressor no more looking for a gas station for air. Just push the button an bingo air bags air up. All the parts needed to do this job is right there in the kit. Took less than 2 hours to install. Hard part is finding a good spot for the compressor.
I would recommend this compressor and the air bags to go with it. I put both the air bags and compressor in my 2004 Ford 4x4 in an afternoon. My only complaint is the "Y" adapter which was broken when I received it but was replaced when I emailed SD Truck. The "Y" adapter does work but is fragile and they need to come up with a better option, but overall I would purchase the system again. My truck no longer sags when my car trailer is hooked on and loaded down.
