Best gear ratio for 31s?
#4
I'm running 3:73s with 31s and I don't have any issue with its acceleration. You have to remember that its a heavy SUV not designed to be fast particularly when you start to modify things like putting heavy tires on it. If you really want to change out the gearing you could just up to something like 4:10s and that may give you the desired "get up and go" you are looking for! Also don't forget that lower gearing means less mpg's so if that's a concern for you keep it in mind

The lowest I would go is 4.10 if you do mostly city or off-road driving. If you do a lot of mixed highway driving with the occasional off road excursion and are concerned about your MPG then the 3.73 gears are quite well matched to 31x10's. I think with 31's and 4.10 gears your highway cruising RPM would be fairly high.

Lots of pavement, looking for mileage, 3.73 for sure, even stock 3.42 gearing is good with 31s. But, 4.10s would give you the "more get up and go" you are looking for since you already have the 3.73s.
