I have a 2011 Ram 2500 2wd. I have installed a 3" coil spacer in front and 2" add a leaf in the rear. My problem now is that every since the coil spacer has been installed, when I make a turn or hit some bumps its makes a clunking sound in front. I have read that it's not good to stack the OEM rubber isolator on top of it but is there a isolator or polyurethane spacer to squeeze in to stop the noise or did I miss something that I was suppose to install the OEM isolator. Any help would be appreciated. Thanks in advanced!
