Gearing for rubicons and 33's

Or those of you with rubicons and 33's what gearing are you using with a manual transmission? Is 4.10 sufficient or ds you go lower to 4.56 or 4.88?

Just curious...

4.10 is fine for 33s.

Okay. I have a 2.5L and NP231, so wasn't sure if the 4.0 and 241 t-case made things different.

Thanks for the info!

A 2.5 will not need the same gearing as the rubicons 4.0

A 4.0,33's and 4.11's are ok
2.5,33's and 4.11's equal........suckazz you would need something like 4.88 for the 2.5,maybe taller

i put 33x12.50x15 on last friday. i did some driving yesterday and when i had 32x11.50x15 it was hard on the 2.5, this quote is corect in saying you need 4.88s with 33 inch tires with a 2.5. i am dropping mine off this friday to have the 4.88s installed. it will bring it back like it is stock with the factory size tires.

It'll definitely make it different. For a Rubi with the 4.0L and 5 speed, 4.10s will be pretty good, but 4.56 would be ideal. Most people don't regear to that because it's only one step higher. Your 2.5L needs more rpms to get it going and stepping up to 4.88 would be ideal for you.

My 2.5L already has the 4.88's.

My coworker just picked up an 06 Rubi and wants to go with bigger tires, so I was just wanting to see if a regear would be in the future. I didn't think it was necessary, but wanted to check...
