4.88s and 37s

Good to know everyone is happy with the 4:88's as that is the direction I'm planning to go when I jump from the 35's. Still running the 4:10's for now but know they won't cut it with the 37s.

I’m surviving with 4.10’s but I haven’t had any big climbs. I definitely noticed the sluggishness in the dirt climbing up and down hills.
 
In my 3.6L JL I put about 20K on the stock 4.10’s with 37’s, it’s doable and had I not known any better I probably wouldn’t have any complaints.

The 4.88’s and 37’s are nice, adds a lot more low end grunt. I noticed it more around town and on the trail than anywhere else but it does like to shift into 8th gear a lot more on the highway.
 
I’m waffling at the moment. Will be going to 37s. Live in flatland of Houston. But, it’s primary towing vehicle at the moment.
I thought the same as you with my JKU, IMO the 4.88 made for a better towing vehicle w/37's

On the JLU it did okay but I never saw eighth gear when towing, 4.88 brought it back more often than not.
Just towed a 4x8 enclosed trailer with probably more weight than it should have had, and doing the speed limit wasn't an issue; even across I-70 at 80 mph but I kept it at 70 (55mph on the trailer fender every time I check the rear view mirrors LOL).

On some of the steeper climbs I had to tap the gas to get it to shift otherwise it was getting too close to redlining and the check engine light would pop up
