I have had my 2006 2500 MegaCab 2wd for about 2 months and 2600 miles. Last weekend, I installed the DayStar 1.5" leveling kit - it lifted the front of the truck about 1" total. Yesterday, I called Michelin about the tire sidewall cracks and today got some 285/70/17 BFG AT KO installed at the local Discount Tire. Love the look of these tires over the stock ones but that is about as big as you can go with the 1.5" spacer. I also took the truck in for an alignment check and as others have stated the toe-in needed to be corrected after adding the 1.5" spacer.

Here is a pic of the truck with the stock tires and without the leveling kit


Here are a few pics with the leveling kit and the new tires (yeah I know the truck is dirty -it's been raining off and on for over a month now!!)

 

nice truck, but wash it plz!!!
