Well your stock axles are about 60" wide
As far as gears I would say minimum 4.88s with 35s and even lower with bigger tires
5.13s wouldn't be a bad idea with a 2.5

This is a subject that is mostly opinion. 10 different people will give you 10 different answers. A lot of it depends on what you are going to do with the jeep. Trails, dd, rocks, mud, ect.

very true but i did the math one day and 31s with 4.10 is about the same as 35s with 4.88s if that helps any
i know my 2.5 barely pulls 5th with 31s and 4.10s

A lower ratio in the axle makes for less stress on the motor because it makes it easier to get everything moving
And if you are thinking about on the highway if you have 37s with 4.88 your rpms will probably be lower
Do the math some times
I think part if my problem is the t5 transmission we swapped in has a higher overdrive plus the added wind resistance of a yj 4 inches higher haha

If you don't find them there I would recommend Ron's machine service, they are very knowledgable and have great prices too, I would recommend to call them to get the best deal

You aren't going to find a 60/14 bolt combo in the junkyard that is 60" wide. That would be custom width.

The narrowest stock 14-bolt is going to be one with C&C hubs at around 64.5" wide. The Front dana 60s that most want are Ford or Chevy and they are usually around 69" wide.
