Hi, New guy here. We have a NTU 2000 Coleman Niagara. I am looking to raise the PUP ride height up a bit. It bottoms out barely going in and out of the driveway... I am aware of the "axle flip" but I am only looking to raise it up an inch or two. We currently us a 2x6 to keep from bottoming out in the driveway. There is another set of holes in the front of the spring mounts that could give us a little bit of lift. Anyone use these or even know about them? Any other suggestions will be appreciated!
