ok, the wife gave me the go ahead for a gear swap and I wanted to know what kind of mpg drop have you guys seen going from 3.23's to 4.10's. I was going to go to 3.73's but why not just go for it. I have a ******* kia at 30mpg and for trips my wife has a 40-50 mpg jetta TDI. I only drive my truck on weekends and 1 day to work. what do you guys think. my tire size is 275/45.20.

Oh and oem Is what I want to run, but what other brands have yall had good luck out of.
thanks

 

You will be fine with a 4.10, since my swap this weekend I have put almost 100 miles on the truck, burnt only about 1/8 tank, that is on a untuned 6.0. with a 3200 stall. You will be a lil less then a 410 ratio with that tire size...

what brand gear did you go with and any noise?

 

Heck, you might see a gain in mpg around town. Do it!

 

around town you would think it would be better...just think...more tq multiplication...easier takeoff for the motor...less fuel used...right?

It's a toy.
Get 4.10s and forget about gas.
You won't lose more than a couple mpg overall.
BTW your 3.23s SUCK!
4.10s will make more of a peformance improvement than all the other stuff you've done to the truck so far.

-And, before you start an LSD thread, just get a TrueTrac with the gears.

LOL, have fun

 

cool, sounds like 4.10's it is. I took out the g 80 and went eaton posi , so that is taken care of. I do not want noise, so besides gm gears, what other brands have you guys had luck with?

 

Get Yukons IMO.

 

Go withthe 4.10's. I have 3.73's and now I wish I went with the 4.10s.

 

I went with yukon gears, a true track, shimmed it to 6k and it is as quit as a dead mouse..
