My last JKU 4 door was lifted and loaded with bumpers winch etc. I did a re- gear to 4:88 and it did great.

My question is this. I currently own a JKUR with manual trans, 4:10 gears and. Cold air intake. It runs good but I have nothing reay to compare it to. Is there anybody that has the. Same set up that defeated? If so what gear did you choose. Oh yea. I currently run. 37x12:50x17

 

What year do you have? I had an 08 with 35's and a stick for a while running 3.73. Wasn't too bad but still ended up going to 4.88s. I hated it off-road with 3.73 but it was livable on road
I now have a 14 jkur with a stick and I'm hoping the extra power will be fine with 37's and stock 4.10s. Hoping the 4.1:1 off-road will still be low enough off-road.

 

How did you like the 4:88s when offroad? Did you ever wish you had the 5:13s?

 

I see you have 35"km2's also. 4.88's were too low on the highway with a stick. Would probably be just right with an auto since the km2’s only calibrate to 33.5" tall with a super chips and gps.

Offroad though, I loved them since my "x" had the 2.72:1 transfercase. 3.73's were way too tall to crawl in the rocks.

 

How are some of you guys revving so high I the highway, I have 3.21 gears on a 3.8l 6 speed standard I lost 6th gear but even in 5th at 100km/h I'm only at 1900 rpm

 

My 4:88 with auto on the highway was fine. Kinda wish I too went with 5:13. But my 08 6 speed I just don't know. I was thinking 4:88 would be too low for a daily driver also

 

My opinion with 35" km2 and a 6-speed is to go 4.56's.
If you're gonna step up to true 35’s or ever go to 37’s - get the 4.88’s ( with 6-speed).
Guys with autos tend to go one step lower on gear ratios than 6-speeds.

Oh, and I was pushing close to 3k rpm's at 70.

 

But like I said I'm not sure if I still have factory 4:10 gears. I need to jack up the rear end and spin the tires to be for sure

 

Automatic or standard?
