4.56's gears and Truetracs finally installed !!
Just received my truck yesterday after waiting 3 weeks in the shop. Not because it took that long to do the work, but because parts were still coming in.
Its a 2001 Screw 4x4 5.4L. 33" mud tires on 20's. I was originally going to install 4.11's as I had read everywhere it was a good choice...boy am I glad I went with 4.56's and Truetracs for both front and rear differentials!
So for anyone undecided on what gears to go with I fully recommend 4.56's
Pros: Shaved a full second from 0-60, Can break tires loose from dead stop, Way more torque, Will put a smile on your face every time.
Cons: Bad fuel mileage on highway, High RPMS at highway speeds.
Here are some before and after Pics/Vids:

Interesting, I was going to go with 4:10s with either 305/70/17s or 305/55/20s later on but I'll have my supercharger on by then. Maybe I should rethink things

I'm afraid MPG's will vary from user to user, as I tend to have a very heavy foot. I will try my best to give you some rough estimates.
Before the swap I was getting around 12-13 on the highway. So I can imagine I lost about 2mps.
I really don't care too much about mpgs at this point, since I knew what I was getting myself into from the beginning.
