I have the same truck, same lift, same color. All I can say is;
1. 37" Swampers will fit without fender trimming;
2. Swap out that #6 plate for a #4. Push it back a few thousandths. If you're planning on a DTT trans, you'll thank yourself for the #4 later.
3. Call Bill K. He can walk you through some vb mods that'll hold everything together until you come up with the $$$ for the DTT stuff
4. The #4 with the 3K GSK will break those 37's loose on dry pavement.
If you're married, and your wife is anything like mine, don't take her on the test drive. She'll never ride with you again. I kept hearing "Why do you have to drive this fast in a truck this big?"... ...
You'll already be making much more power than the stock trans can handle, so save your money for the DTT stuff before you go for a bigger turbo... . My . 02 worth... .
