I'm running them, Ram 2500 CTD quad cab short bed, they're great w/a load, I noticed a huge difference w/a load, towing a trailer, cab full of guys to SandLake or the like. When empty, they make for a pretty stiff ride in the rear even w/just a few pounds of Hg. Firestone setup, just ran lines to the rear bumper, we had to get out of town for a trip and I've just never gotten around to installing the tank/compressor/guage cluster that I have for onboard adjustments.
had to get a spacer to match my lift
tried to get creative w/my airstem mounting
