I have the dual air shocks up front, I don't have any plumbing or a compressor. I did tie them together with a HOKE so I could open that valve to max out articulation but I find I hardly use it, so if you do the pairs and just connect each side independently you will be fine, just use a PSI gauge to be sure they are balanced. It is hands down the softest most plush ride you can get for under $200 all in. And, It can articulate a LOT more than any of these high dollar shocks because they still spring bind.
Thanks for the reply! That is mostly what I'm looking for just a smoother ride. And you just left the stock springs alone on back? What psi do you normally run yours at for the best ride? Have read some folks have had problems with the upper shock mount welds up front after going to air have you experienced any issues with your ride?
