R U planning on going to 35” tires soon…
To me, the 4.88s will be a little deep for highway driving, you will definitely get a seat of the pant feel form the lower gears.
If you do the math you will see going from 31s (stock) to 33s you should run something in the neighborhood of 4.30 do 4.56 will be the best match for added power and a better than stock response.
Just commenting not trying to get you to change.
What do you plan on doing with the truck, off road a lot, just trail riding or mostly highway/street ?
