regearing

[Red_Diesel]

Does my truck with 37's need gears? ive heard if you go past 37's you need them, but ive also heard i do. But im thinkin about gettin them. im thinkin about 4.30 gears, will it help my mpg? On powerstroke help .org he says that lifted powerstrokes with stock runnin gears will eat threw transmissions. I dont want to have to replace my tranny. i also plan on adding performance parts to my truck to, like tuner and injectors. I want my truck to last and want to increase my mpg.

Yes, I would re-gear if I were you.

4.56 would be a good combination with your tire size.Would help with MPG'S too.

Dont do it... If your planning on adding power, dont.

I loved my truck with 37's and 3.73's... The power is there when you need it, and crusing down the hwy at 80 your sitting right at 2000 RPM's

With the 4.30's I am at 2400 or so. I'll take a quick pic tomorrow.

As far as the tranny comment, the factory tranny will not hold up to factory power, has nothing to do with the size of the tires. This truck ate the first tranny at 24k... It was on factory tires.

If you think about regearing go no bigger then 4.10's...

Please. You will not be happy.
