like this ok?

 

On highway, it's not great, but it gets the job done. Off road, it's more than enough if you're geared properly for 37's.

 

Thanks so much

 

what kind drive shaft you do

1310 or 1350 for 37 tire

thansk

 

 

depends on how hard you are going to wheel it.

if you go crazy the 1350 if you just wheel mild trail then 1310

 

like moab and rubicon trail

 

I have an '08 JKU 6spd with 37s and 4.88s in the rears. Pulls fine on the highway, will hold and pull doing 70-80 all day in 6th on the freeway.

 

I went a little more & went w/5.13's w/37's. 11 Rubi Unltd w/6 speed. So far so good. Like said earlier off road is good, but on road, ehhhh.

 

I'd actually say it is very much about where 1st gear was when stock, maybe a hair lower. I personally think the 4.88 are a perfect match for 37s WITH a 6spd manual. I thought about 5.13s but felt it would be too low for how much time I'm on the road and not offroad.
The 4.88s pulls and accelerates nicely, too me very close to stock and has just enough rpm's above stock to handle the additional heft of the tires, aftermarket bumpers, etc.
