I'm curious what gear ratio I should go with. I have a 2009 Automatic 4 door rubicon with the 4.10 gears and currently have Toyo MT 33's with only 3000 miles. I would like to do my gears before I put 35's on so I'm curious what gears you would get with the plan to switch to 35's once the tread on the 33's is no good? I imagine I'll have the 33's for a couple years at least. I see some people go with 5.10's and 5.38's for 35's, but would that be too much with my current 33's?

This is from the FAQ section.


Q: What gear ratio should I be running with 35" tires?
A: In order to bring your Jeep's performance back to stock, you will need to run 4.88 gears with 35" tires. However, if you are looking for a little extra power, you should consider getting 5.13's. This is especially desirable if you have an automatic


Imo, if you have an auto , you'll love the 5.13's with 33's or 35's. My 35's are worn down to 33.5 and it's just fine. If you have a stick, you may want 4.88's

How do you like the 4.1's with the 33's? If you like them, then I say 4.88. If you find your self looking for a little more power in the low end now, I'd bump it up to 5.13 for 35's.

My only reason for wanting to regear early is camping trips... hauling 2-3 people, 2 dogs, and sometimes pulling a little cargo trailer. Going up those hills is a real PITA! ... with my 4.10's and 33's that is. I find my Jeep constantly downshifting and hitting 4500 rpms etc.

I'd like to be able to stay in OD comfortably while going up and down the mountains at around 65-70mph.

Anyway, ya I might just hold onto the money and wait till I need to replace tires. Perhaps I could just settle for a flashpaq for now.

Go with 5.13 so at least you can go to 37 if you ever wantt to and be good and 35's youll have nice power but if you really plan to monster get some 5.38's
