m16ty Posted October 21, 2015 Share Posted October 21, 2015 My RD822sx doesn't have air-ride cab and with a beam suspension, the cab could use the extra cushion.My brother has a RD688 with air ride and after looking at it, it looks like all you have to do is replace the back bushings with the air-ride bags and associated parts.My question is, will the air-ride work with the metal hood? I'm just not sure there will be enough flex between the metal hood and cab for the air-ride to operate.

kscarbel2 Posted October 21, 2015 Share Posted October 21, 2015 The answer is yes. And there's a Mack service bulletin that lays out the parts required and installation. Now whether or not those parts are still available thru the Volvo parts distribution system is another matter.

m16ty Posted November 3, 2015 Author Share Posted November 3, 2015 I know where there are a couple of R model parts trucks sitting. I'll start there.
