CharlieK Posted March 23, 2014 Share Posted March 23, 2014 Howdy! First time posting!I have a 1980 RD612 (looks like that's how you refer to the model?)I'm curious how to go about making the cab air ride. Is it as simple as getting rid of the rear center cab mount and installing an air bag/shocks? Anything else need to be done?Is there a kit available? Or is it just something to make up as you go along?Thanks,Charlie Quote Link to comment Share on other sites More sharing options...
gearhead204 Posted March 23, 2014 Share Posted March 23, 2014 I don't have a solid mount to look at but I believe one will replace the other my advice is hit the wrecking yard and take a good look at a air ride cab and cross member mounting Quote Link to comment Share on other sites More sharing options...
j hancock Posted March 23, 2014 Share Posted March 23, 2014 Air ride cab would need new front and rear mounts to start with. The cab pivots on a rubber bushing in the front mount.No Mack kit. Salvage yard at this point.Forgot to say Welcome! Quote JimIt doesn't cost anything to pay attention. Link to comment Share on other sites More sharing options...
Macktech689 Posted March 23, 2014 Share Posted March 23, 2014 Check out the cab-mate kit on stengelbros.com website. The R600 kit is just under $800 Quote Link to comment Share on other sites More sharing options...
ws721 Posted March 23, 2014 Share Posted March 23, 2014 Also make sure your hood "seats". where the hood rest. That should have the roller. Check how your radiator supports. Do they come off the fire wall on cab or from the frame? Otherwise your radiator will be rocking back and forth Quote Remember if it's got a hood it's no good!

CharlieK Posted March 23, 2014 Author Share Posted March 23, 2014 See if those pictures work...The front of the cab has what I would call pivoting mounts... Second picture is the back of the cab. (if they load)The radiator does have rods going to the firewall, but the radiator is mounted on the bottom, with rubber mounts, almost like it is supposed to pivot... But, that's just my impression. The hood to cab rest... The hood has a rubber block, the cab has a 4"? diameter round plate at an angle. Once again, giving me the impression that its there to allow movement.

CharlieK Posted March 23, 2014 Author Share Posted March 23, 2014 And another thing... Going off the vin#, this truck is only supposed to be a single axle.... But its not! I'm not sure how much of it has been changed/modified from its glory days... Quote Link to comment Share on other sites More sharing options...
pmolitor Posted March 31, 2014 Share Posted March 31, 2014 Should be an easy swap with most any eastern r/rd model. The air ride replaces the rubber bushing on the rear cab mount. The front cab mounts stay the same. Hood and radiator mounts are just as the other responses say. Should be an easy bone yard find. Quote Link to comment Share on other sites More sharing options...
