I have your answer
how's it going.... shocks will help ride quality. I hope those shocks have the correct travel, with my 4/6 IHC setup on the rear I went with KYB gas-adjust shocks but they are not specific for the Ram. When you purchase the IHC kit they mod the rear shocks to fit the mounting bolts. These rear shocks are spec'd for 2k Isuzu trooper, I looked up the specs and they work for Ram rear setup.
At a 5" rear drop your bottoming out the shocks and the only thing that is keeping you from hitting frame is the bump stops. I had to remove my oe bump stops w/ cup and install shorter ones. Then you have to worry about the rear upper control arm bracket hitting the frame.
From what I remember your truck... IMO you need to install the
illicit customs rear correction kit (cut or non-cut) or
Inez Hotrods Customs cut version. Those bracket will correct pinion angle, center the wheel and eliminate vibration. If you get the cut version brackets you don't have to worry about hitting the frame.
I personally went with the IHC kit w/o the rear shocks, cut the rear upper control arm brackets and installed the IHC correction brackets which I will be switching to the Illicit brackets. I remember telling you that it was a PITA to install the IHC setup but it's doable.
My ride quality is stiffer than stock but it's not bad for a daily driver. I'm happy with my setup...
