My friends 2010 has a 2" and it looks good so maybe I'll get the 2

 

2010 trucks sit way different than yours, so it won't come out exactly the same. But, I would still recommend the 2". It'll bring the front end up quite a bit, but you'll still have a tiny bit of rake for towing and hauling.

Once you level it, you're probably going to want larger tries to fill out the wheel well gaps.

33's would be a good choice.

 

Just measure from the center of the wheel hub to the top/center of the wheel well. Figure out what the difference is from the front to the rear. My 07 4x4 is 2" different. Still I wouldn't recommend more than 2" with a 4x4 it will put to much of an angle on the CV joints and you will tear up boots. Some say you can do 2.5" with no problem but I'd just measure it to be sure you don't end up with a CaliRake.
