I just bought a new AWD SS and it suck on gas. has anyone swapped the 4.10 to 3.73?

 

You bought an AWD TBSS for gas mileage?

 

My thoughts exactly...

 

Plus you're willing to spend $500 on a gear swap to save $10 a tank. Smart move chief.

 

I have a set of 3.73 I would trade you strait across for the 4.10s, but you will still need another set for the other diff. PM me if you want.

 

if im not mistaken the tbss has a 14bolt, which is different from 10 bolt gears

 

i have a stock set of 3.73's if your interested. pm me if your interested. you should have the same rearend that i do.

 

I have a 2wd and I changed to a 3:42 and I love the gearing..Go down the highway at 2k rpms doing 74mph....My city driving went to 18 almost 19 and highway 22mpg...Mine has a ton of bolt-ons so I couldnt tell much of a differencr in performance..I went to 3:42's cause I have heads and a MP122HH for my truck also...But i love th gear without those mods..Runs killer from a roll..Actually is faster from the roll than before..Slower out of the whole..Not much

 

way to be a couple of *********.

 

swaping to a 3.73 you wont gain that much mpg. if you go to a 3.42 you will really loose your take off. a good tune will help you out some but not a whole lot.
