I’m currently running into issues w/my 2019 5th gen 1500 ORP w/3.5” readylift, getting rubbing on the springs. Readylift states this can possibly be resolved with removing the preload spacer, truck goes back into shop to see if it corrects the issue. Truck was making clunking noises from passenger side and slightly from driver side. Readylift states the kit will work on ORP as long as your measurement from Hub center to top of wheel well doesn’t exceed 26” I’m sitting a pinch over 25” so they’re abit baffled (smh)
