I've read two different ways to level your truck, by taking out the rear spacers or by adding a coil shims, I'm still waiting on my truck, and I never reallt noticed the high rear end until I started ready these articles. Is there any difference between the 2500 and the 3500, by the looks of it the 3500 sits a little more level. I really don't want to add bigger tires, and all the shim from daystar are for a 2 inch lift. Just one more comment, is there any negative impacts by leveling the truck
