question about gears

[Jon581]

My truck is a 2007 sport and i wanted to know what the pro's and con's would be for switching my 4.10's to 3.73's

worse accelleration with the 3.0

 

[WIDTIO]

pro- better highway cruiser

con- more stress on tranny, slow excelleration, etc.

do you have a certain reason?

 

[Jon581]

i just thought 4.10's were a bit much for a 2wd 3.0 and at 80 mph im at 3000rpms and what do you mean by more stress on tranny?

 

[triumphrider-1]

Nah, not for the 3.0

If you really want, make your next set of tires slightly larger than the stock ones, that will lower your RPMs a little. I have 265/75-16s and I run about 70-72MPH at around 2500rpm.

by the time i need new tires im going to have 18's on there so that wont make much of a diff i was just thinking it would be better to have slightly lower gears.

 

[Sasquatch_Ryda]

Lower gears in the diffs = less stress on the tranny because its 'easier' for it to turn the tires

 

[Sunk]

It came from the factory that way for a reason. A 3.0 can spin 3,000 RPM all day long and be just fine and dandy.

 

[4x4junkie]

Agreed. 3000 RPM is nothing for the 3.0L. You may actually lose some MPG if you go shallower on the gears.

Your 4.10s are fine. My g/f's 2008 Ranger came with 4:10s, and it has a 4.0L.

 

[Jon581]

since everyone agree's the 4.10's are fine i'm going to leave them thanks for your help

3.73 is "easier" to turn than 4.10's? i dont think so.

Higher the number the lower the gears...

 

[WIDTIO]

Higher the number the lower the gears...

ya i know i dont think thats what he was sayin though..

 

[Sasquatch_Ryda]

I didn't say that 3.73's would be easier to turn, I said the 4.10's would be easier.
