I have 06 wrangler unlimited with 3" old man emu lift and 31" tires. want to go at least to 32" but have been told that I need to change 3.73 to 4.10 do I just have to change ring and pinion gears or more?
Welcome to WF! I've got 3.73's and 33x12.5x10's and it's only a little noticable differance. For the cost, 4.10 isn't really worth it. If you really need more power, check this thread http://www.wranglerforum.com/tj-chat...tion-9355.html. I think it is really helpful.
