Go to one of the online 4x4 places that sells tires. Usually they have a gear ratio guide on tire size. I think a lot go with 4.56.
Here's a link to a chart

now is this based on gas or diesel engines? or both?
because based on the chart with 37's i should run either 4.56 or 4.88 gears

You very probably have 3.73s in an '06/6.0L/SRW. Cartmanea has 4.30s with 35s and I think he likes them, anything less that 4.30s isn't going to be enough of a difference to notice probably. 4.56s would be better for the bottom end and tranny.

It's a different axle, not the same size as the back; it's a D60, and there's a carrier break at 4.10, so if you go 4.30 or deeper you'll want to buy the "thick" gears to fit a 4.10/smaller case.
