snowman_w900 Posted June 17, 2020 Share Posted June 17, 2020 (edited) Good evening guys, I'm wanting to put air ride suspension and update my 1989 MH cabover. I found a very clean 2006 Mack CXN with CRDPC92/93 rears, 3:86 gears on Mack air ride. Cab is trashed, but the rest of the truck is great shape. Issue I'm having is frame rail height. Has anyone ever added a newer Mack cutoff to an older Mack truck like im wanting to do? I came up with this: MH frame rail height 9.5" outside to outside 2006 CXN frame rail height is about 10.5" outside to outside I'm trying to decide on how I need to do this other than buy new rails and drilling them. I'd like to use what I have. I'm looking for opinions and ideas. Edited June 17, 2020 by snowman_w900 Quote Link to comment Share on other sites More sharing options...
