Here's mine on 3.5" lift

 

So straight up. What would happen if I went 35's and stock 08 X gears?

 

Your on an auto? What gears do you have now?

 

Are u running 3.21s stock? If so u can do it. It ain't great but doable. U will rarely use 4th and never 5th or 6th gear. Off road it will blow goats as u will have to use 4LO in any kind of hilly terrain. It's doable, are u gonna be happy? Prolly not.


Here's mine running 35s with a TF 2.5" coil lift.

 

If u have the 3.21 gears or even 3.73 gears on an auto. U will probably not enjoy it too much. That's just what I have seen from others with auto's. I have a stick and with 3.73 gears I am happy. I still have plenty of git up and go!

I have a RC 2.5 inch coil and 315/70/17 duratracs.

 

Mine is an auto. How do I find out what gears I have?

 

Here's my two door on 35's. I lost some gas mileage but i love it. Mine is an automatic too. I had to take it out of overdrive on highway inclines. I installed the cruise control kit and it made it a LOT easier driving long distances. I have a 45 minute drive one way on Mon, Wed, and Fri.

 

What sizes wheels are on your JK? Are those 18s?

 

They're 17's

 

It isn't terrible with 3.73's. I'm sure it would be better with 4.88s , but I'm worried about breaking a pinion on the 30 with that deep of a gear and alloy shafts.
