Ran 4.56 on 37s on my sierra and loved it.
What he said.....^^^
4.56 at the minimum and at this point, that is the highest (numerically) we can go.
If there was 4.88 option, that is the route I would have went with my '12
But if your front diff axle is the same as the '12, as I dont see if being different, you will require another front diff axle from a '10/'11 as the gear is welded in.
THis is assuming you have a 4wd truck.
The rear will require machining to get the gear in place.
Not an easy task, but definitely worth it.
I lasted on my 37's and 3.55 (you are far better off than I was) 2 weeks before swapping the gears.
This is my first truck and was new to the whole gear changes as well.
