Please be patient, this is my first Dodge truck, traded up from 05 GMC 2500HD 6.0L gas 4x2. Now have 2007 Ram 2500 Quad Cab4x4 Lone Star with the new 6.7L CTD. My question is... How can I find out what the rear axle ratio is? My window sticker says "11.50 rear axle"

um....

 

Manual or auto? I believe it is 3.73.

 

I think it is 3.73 as well.

 

It is the 6-speed auto. I'm currently searching the Dodge website and they indicate that the 10.50 has a ratio of 3.73. I am leaning toward the 11.50 being the 4.10, but haven't found anything toprove that yet.

 

Ooh yeah, welcome aboard and

3.73's. . .if you had 4.10's it would say on the window sticker

 

Thanks to all. Looks like the 4.10 is a $50 add on this truck.
