So I just found out my 13 jku rubicon has 3.73s not 4.10s, surprised is an understatement . My plans were 4 in lift and 35s figuring the 4.10s would fine without regearing but now with higher gears guess I'll have to regear anyways so should I go 4.56 or 4.88 and 37s? Or will the 3.73 be ok with 35 s? Any input thanks

I have the same setup on 35's with a 2.5 lift 4 is way to much for 35's

I've been running 35s on my 13 JKUR auto with 3.73s for a while. It's not ideal but it's doable. I'll switch to 4.56 when I can afford it. It hints a bit but that can be overcome by shifting manually if it really bothers you.

I have some 4.10 out of my 13 rubi for cheap if you want them.

I believe that the 3.73 is the standard for the rubicon and the 4.10 is an option, well thats how it was when I bought my 12'

Nice that's probably what I'll do too I guess I'll get my gear piggy bank started

Mattgt5 how much you trying to get for them depends on price it might worth it to just put them in for now, not sure how much a shop would charge me to do it not sure if I wanna tackle that myself

Egeli yea that's what I found out about mine I almost got into an argument with a guy that mine had 4.10s guess I gotta eat a little crow he was right

3.73 is standard on the rubi auto, 4.10 is standard on the rubi manual.

Yea mine is auto and found out the trans case is 4.10 ratio so in 4x4 it is 4.10 just not daily driving my buddy's 13 jk sport has a 2.72 trans case
