Here are the prices I have found for the bags. right at 500 for the bags installed and a manual fill valve. I can get the bags, compressor, and dash switch/gauge kit for $900.00 installed. The final option is the bags, bigger compressor and wireless controller with gauge and auto settings for $1100.00.
Does this sound right?
For me it is hard to tell. I did the install myself. I have the Ride Rites with the compressor and manual control w/gauge on my dash.
I paid $274 for the bags and another $211 for the compressor both off Amazon.com Option 2 is going to cost you $400 in labor. I guess if you can't do the job yourself it is worth it. Two of my friends have option 3 with the wireless remote and auto fill/deflate. That system is pretty slick.
