So the gears are not great and you need 5.13s.I've got the max tow with 37's and the gears seem to be great compared to the 373's I had on my JK. The 8 speed on the other hand leaves a little to be desired. I have not programmed it yet to reflect tire size increase so I'm not sure if that will help with shift points. 8th gear is useless above ~55mph. It is hesitant to shift into 7th gear and stays well above 3000 rpms even when not accelerating. I am getting worse gas mileage than I did on my JK.
Get a Tazer and reprogram it and you will see better shifts. I have 37s and 4.10s on mine and before the program, it would hunt for gearing - constantly fluctuating between 6th and 7th gear. Now with the reprogram from the Tazer, it cruises in 8th at 70 mph no problem and only occasionally drops into 7th on small hills. This is the first tank with the reprogram so I can't say yet about mpg.I've got the max tow with 37's and the gears seem to be great compared to the 373's I had on my JK.

What Ted said. Have 35's and have reprogrammed for the tire size. Highway speeds are no problem, easily cruise at 70-80 no problem. Gas mileage suffers a bit, average 16.9 mpg with a mix of highway and street driving.Get a Tazer and reprogram it and you will see better shifts.

That’s not bad for MPG on a heavy box flying around on big tires.What Ted said. Have 35's and have reprogrammed for the tire size. Highway speeds are no problem, easily cruise at 70-80 no problem. Gas mileage suffers a bit, average 16.9 mpg with a mix of highway and street driving.
My experience exactly. Right at 17 MPGs, runs fine at any speed, but it doesn't like to stay in 8th gear much anymore. Only if the road is flat and there isn't a headwind.What Ted said.

I have 37's and 4:10's. The tranny sucked until I recalibrated with my Tazer. It makes a HUGE difference in shifting performance! It is fairly flat where I live, and I frequently see 7th and 8th gears. Tranny shifts very smooth!I've got the max tow with 37's and the gears seem to be great compared to the 373's I had on my JK.

I had a maxtow on 35's for 40k miles. It got 14.5MPG mixed. Mostly due to the hills around me on the highways and the highway speeds are 75-80mph.How are the Max Tow 4.10s and the 8spd. behaving with the 35s.
