A near perfect solution
This is my second AirLift wireless system... this one was a compressor and controller for an existing air bag installation. I believe the quoted install time of an hour is understated, about 2-3 hours allowing for planning and proper mounting. There was insufficient tubing in the kit for my long-bed crew cab F350 in spite of mounting the compressor and controller behind the rear seat. Regardless, its a near perfect air suspension solution and I wouldn't hesitate to buy a third one ...
Load Lifter Dual Path
The unit works well and went on in a justifiable time. The only conplaint is the air pressure gauges need to be of a higher quality. The gauges will not stay stationary while vehicle is in motion. This was the most annoying part of the unit. Maybe a oil filled gauge would perform better.
