Do you really need to ask this question?
4:56, of course.

 

ok so this is probably a really dumb noob question but please dont ride me to hard! lol what is the difference between the differnet gear ratios? i have the 3.55 gears. what makes the 4.56 better?

 

the 4.56s is one more complete rotation than the 3.55s this makes it easier to turn bigger tires

 

so basicly the 4.56 gears put power to the ground more effectively right?

 

Mainly, torque to the rear wheels will be greatly increased, stress to the transmission and other driveline components will be greatly reduced and engine effeciency will be increased...

 

sweet! now the question is how much is it gonna cost me to get it changed! lol oh well its only paper!

 

around 600-800 per axle. is your 2wd or 4?

 

2wd. geez! thats gonna have to wait a while!! in all seriousness though thats not as bad as i thought it would be. ill have to do some shopping around see if i can find a decent shop around here.

 

what are the pros and cons of going 4:10 vs 4:56? Im at least going 4:10 but am wondering what my power and mileage will be with either. I do half city and half highway driving. And I do tow my boat that isnt light. I found a shop that will swap front and rear for a $1000.00 btw

 

Don't even mess with 4.10s, the 4.56s would only be turning about 300 more rpm at highway speed, mpg loss would be just about un-noticeable, but that little bit of added rpm would be enough to keep the tranny from searching for the right gear and would keep you in the "sweet spot" more effectively...
