Poly spacers are to increase rear spring height. They look like a donut that is depressed on one side in order to slip onto the tops of the springs. I think you mean wheel spacers which from what I've read, are somewhat iffy on the safety side of things..Poly spacers: I talked with Ldub who uses 1" spacers for his wheels. I love the look of his VX, but if I had the diff drop brackets, wouldn't 2" be better for wheel well clearance/less beating with the hammer. Also, I have read that these can fall out at high levels of travel. Is there a good way to ensure that this doesn't happen?
Not sure on this but very interested. I would like to give my vx a little wider stance if this is what I need for that.
