I agree. This is a job where experience and a warranty are a big asset.

4.10 is like in between gearing, better but not best, go ahead and bump it on up, then you realize torque to the ground is there.

I've only got 33" tires. I think 4.56 would be a little too much.

I'm guessing you don't have a 4WD, but correct me if I'm wrong.
What about going with 4.30's? It's only available for 2WD guys, but that sounds like a good middle ground for you.

I'll look. The 9.75" is really limited on aftermarket gears

I forgot about that. It's available with the 8.8 but I don't see it with the 9.75

My buddy replaced a burnt up ranger rear end with a used 75k junkyard unit from lqk and it was still $500 for a point of reference in cost.
