Has any body used the 2 1/2 inch leveling kit? Do you need to change shocks or anything else or is the 2 inch the better way to go. I also saw the kits on ebay for $69. free shipping Big Bobs or something. What product do you guys recommend. Thanks for the input Jeff 2007 quad 5. 9 6 speed stock no muffler p. s. how do you fill out your sig.
