Denny Posted August 3, 2011 Share Posted August 3, 2011 Has anybody out there had any experience on converting an R688ST from 3 leaf spring to Newway air ride. Just wandering about the cost and all.

220cummins Posted August 4, 2011 Share Posted August 4, 2011 do you have the rears? do they need any rebuilt or parts ie drums shoes or seals etc? I understand the truck is a r688st(tandem) but trucks can change significately throughout thier life but is the truck a single or tandem axle ie frame rail lengthen and driveshaft lenght? What condition is the frame rails and cross members in? Thats just the major items. Then you have to get into the neway airide system what condtion is that in? does it need new bags, plates, torque arms ..etc. after check all that and everything is good you just gotta take some measurements tear out your old rear drill,layout where the air ride is going drill some holes, get some new hardware, install new air lines, Put your wheel back on. Im not trying to be rude but somemore backround always helps out when asking a question to get the best answer to it. Im starting to do this to my cruiseliner in the fall/winter of this year. I got all my parts for with a lot from good guys on here.
