3.42

The higher ratio won't squeeze fuel like a low will. But the engine isn't working as hard either.
And if you run the western US like I do, you want those 3.58s cause it's much easier to hill climb.

 

Just stuff some 5.29's in there. Only need the top 3 gears then lol.

 

3.42s or 3.36s would be ok with a 13 or an 18 speed. But with a 10 it's gonna be a slug on the hills.
Although the one wrench I know, has their DDs tricked out somehow to have over 500HP in 10th, all done with the ECM.

 

running 22.5LP on 3.42 will run same as 24.5LP on 3.55.

 

I have a 2016 2wd Silverado 1500 with 3:42 gears an I’m just building my truck for show I was curious if my rear end would hold up to 37inch tires an 14wides? On a 8inch lift

Might have better luck on a pickup truck forum. This site is mainly for class 8 commercial trucks.

 

I would think that it would be a real slug on the highway with 3.42.

 

What is 2:53 good for

 

Interstate 10 in Texas or I-15 in Utah once you get it rolling.
