I am trying to find out the axle ratio on my '05 crew cab 4x2 V6. Since the truck is an ST and everything else is standard, I'm assuming its the 3.21. Does Dodge post these numbers anywhere on the vehicle?

 

is it manual or auto?
manual is 3.55, auto is 3.92
as far as i know they didnt produce any 3.21 ratio axels....

 

It should be on a sticker in the glove box...if not check on the front side of your rear axle.

 

WRONG!

My 4.7 Auto came with a 3.55 (standard)

The basic gear ratio is a 3.21....and the 3.55 or 3.92 is a $40 option (it all depends on the truck & model)

The 4.7 HO comes with the 3.92 & 5 speed auto tranny standard (for 2006)


Just give your VIN number to your local Dodge dealer's parts dept. & they will tell you the EXACT vehicle specifics
