I’m trying to decide what rear axle and gear ratio to get. I would like to run 42s was thinking of a sterling 10.5 but only can get gear up to 5.13. So the question is will 5.13 be low enough or go with a 14bolt or a sterling 10.25. I already have a front D60 out of a 08 ford. My jeep is the stock 4.0 with a 6speed.
