4.10s or 4.56 depending on how heavy.

5500 lbs. Towing 5 Times year. And off road 10 times a year

No, how heavy the tires are. 4.10s for relatively light 35s like BFGs, 4.56s for something 10+ lbs heavier per corner. Ratio calculation is only part of it, rotational mass & rolling resistance will also contribute to sluggishness.

OK, so if your stock tires are 29.75~ish tall, 4.10 with 35" would match a stock 3.55:1 ratio.

If you want it sporty, go steeper than that on the gears, especially with heavy tires.

4.56:1 with 35" tires would work out to about a 3.90:1 with stock tires. With that 10 speed, that might be about right for a lot of fun and still have good highway manners.

First gear in the 10 speed is a good bit lower than the 6 speed. You drag racing or pulling stumps?

3.73 ten speed has a lower first gear than a 4.10 six speed.

With the 10 speed, I would not go any further than 4.10's.

I've been searching for a thread like this. I have a 2017 with heavy 35 inch tires. I currently have the 3.31 non limited slip differential. I don't tow, but I do highway driving up a steep grade. Truck downshifts a lot. I was looking to get some 4.56s with trutrac limited slip differentials for both front and rear axles. I need advice Pros and cons will be much appreciated
