Personally I'd say go 4.56s. I have 4.88s and run 37s and it is perfect. I have plenty of power, pulls 6th gear no problem. runs about 2800RPMS at almost 80mph. I wanted to keep my RPMs under 3000 when on the highway and went with the 4.88s instead of 5.13s like everyone recommended. If I had an auto I would of gone that low but with the manual, it has plenty of power and pickup.

I had 5.38 installed with 35" tires. The RPMs run about 2400 to 2500 at 70 mph and that gets about 15.3 mpg. I went from 4.10 to these and was amazed with the ability to drive down the highway without constantly kicking in and out of overdrive.

Just keep in mind that OP has a manual trans which is a completely different animal from the auto.

Nice looking JK by the way!!

Well I decided on the 4.56's the guy doing my gears should have ordered them yesterday so hopefully next week he can get me in the shop and get it done,cant wait this 3.21's and 35's are really starting to get on my nerves especially since I know good power is is only days away.

Will do and since you live in Aurora ,Im am having Bill at Western Drivetrain do the work .I havent met him personally yet just talked on the phone ,but he seems like a stand up kinda guy and stands behind his work. If you have questions give him a shout he is always willing to help out.

I know that motive shows the gears and people who sell them say they can get them but Bill told me he called them and they said 4.56 wont be available till Jan. next year . I havent called myself but I think I will do that right now and post back after I find out.

Funny you mention that. I called him and inquired about the 4.56 and he told me that he couldn't get them because the company he orders his gears from (Yukon) doesn't make them. I'm wondering if having two people asking about them in two days changed his mind, lol. I was going to have Crawlertech in Commerce City do them (Motive Gears), but I might just give Bill a call back. Crawlertech wants $1650 vs. Westerm's $1495, plus they're farther away. Thanks buddy.
