So update. If anyone interested. Got swamped at work. So never took roof rack off.

But. Nothing changed after lighter bumper & fenders

I went to 40’s. &. It went up to 14.2 mpg. Not bad.

now. I upgraded everything underneath to metal cloak. &. Got rid of spare. Fig help off set the added weight of heavier parts.
now.
I’m avg. 13.8. That sux. But looks cool.
Not great still better than the 12. I was originally getting.

What gears would you recommend?

I see you're in Texas, is it mostly flat out there where you wheel? No rock cliffs and the like?

13'S are pretty steep for a truck that spends the majority of time on the road.
Running the consistant higher rpm's on the road really suck the gas down.

I put Mopar crate axles in my '12 Wrangler sport(on 35's) and because the majority of use was on the street, I figured I'd try the 4.10's before switching gears and they worked out good. We do no rock crawling, mostly all old fire trails and timber/logging roads with a few trips to Rausch Creek from time to time and the 4.10 with lockers have been fine, never encountered anything we couldn't navigate.
I do not think I would go above 4.56's for a mainly pavement machine, just my opinion.

I just bought a 2020 Gladiator Launch Rubicon and plan on leaving the 10's in there as well, because this baby will see wayyyy less offroad time that the Wrangler. Starting with 35's and see how that goes.

I like 4.10's for a mostly street driver, again, just my opinion.
I probably would have gone 4.56, or 88's if I was determined to regear.
Our problem is the damn 3.6, we need a hemi

4.10s in a JK with .83-1 top gear is a final drive ratio on the highway/freeway of 3.403-1. With the 8 speeds double overdrive and 5.13 gears you get a final drive ratio of 3.437. That's a negligible difference that would have 0 effect on mpg or driveability. Given the OP has 37s the .03 deeper gearing would help more than it hurts. It's not a gearing problem it's moving a heavy brick with terrible aero stock made far worse by lift and tires through the wind. It will never be good fuel economy period. Sure you can make it better with smaller tires but then what's the point of owning a Jeep?

To each their own my friend.
Have a great holiday season, sucks to be sitting here recovering from a new knee, I can't even go out and play, lol

east tx. Is not really flat There’s a few places around. More trail stuff than rocks.
most people go mudding around here.
not really my thing.
I don’t do any off roading. It’s a work truck My other gladiator is just a sport & was only work truck. So couldn’t risk it getting broke.
But I bought this it was already re geared.
i didn’t do it. This is why had original question. About it. Compared to the sport.
I was just ignorant about gearing & what it helped. / why do it.
But now that I have a back up. & a jeep way more capable. I plan on taking it off road, when I get down time.

I feel like a 5.13 and 40's play well together for street and trail.
When you are discussing good fuel economy and either 40 or 5.13 is mentioned you are really grabbing at straws.
The 3.0 diesel would be your solution.

I think I’ll be happy with it. I might look at diesel for my next one.
I wasn’t really looking for great gas mileage.
it was more just expecting better than I was getting based off of sport with 37. & 3.73 gearing. Vs new one. I was just misunderstanding on what re gearing would accomplish
