FYI: Superior Axle & Gear Jeep JK Wrangler Ring & Pinions will be available at 4Wheel Drive Hardware, Northridge4x4, Off Road Evolution, Quadratec and Redrock4x4.
Well, that is good that they will have gears out soon, better yet they got them low enouph to overcome the Gutless Wonder V6 when your running 35’s or 37’s. Haven’t found any gear calculators yet for this V6’s tourque range, but going off of the factory gearing and past experience it should be pretty close to this:
Standard – 35-37 with 4.88
37-39 with 5.13
Auto – 33-35 with 4.88
35-37 with 5.13
Hope that helps in your planning.
Later,

I have a 08 Sahara unlimited with an automatic and 315 ProComps. I want to change the gears but am not sure of what to go with. I am considering either 4.56 or 4.88. Any help you can give me would be appreciated.

Honestly, you’ll want 4.88’s as they’ll bring your JK back up to stock performance. However, if you want a bit more power, 5.13’s is what I would go with – as a matter of fact, that’s what I had done 🙂
About what is your RPM’s at 65MPH with the 5.13’s? I’m assuming you have the 35’s….?
at 65, you’re close to about 3k
I have a 2007 JK X Wrangler I put on a 3 1/2 short arm lift with 35″ tires
I still have the standard rear end gears.
Would like to know what gear ratio I should change to and I would like to know what lockers would be the best to perchase.
4.88 will bring you back to stock like performance and 5.13’s will give you a boost in power. the downside to 5.13’s is that your RPM’s will be on the high side at highway speeds. As far as lockers go, ARB is what I would recommend.
I have 2010 JK Unlimited. Going with 315s(35s) and looking to stay with highway speeds and power should I look into 4.88s?
4.88’s will bring you back to about stock performance. 5.13’s will give you a boost in power but, your rpm’s will be a bit higher at highway speeds.
