I'm looking to buy a T1N style and would like to know whether the 3500 has a lower rear end ratio than the 2500. Any way to tell what ratio a given vehicle has?
Yes, there's an ID plate on the diff.Any way to tell what ratio a given vehicle has?
I have '04 and '06 brochures for passenger vans (which are all 2500s). They show the 118" wheelbase having 15" wheels, others having 16". All wheelbases show the same differential (one brochure says 3.72, the other says 3.73).Both the 2500 and 3500 were available with a 3.73 or 4.11 rear end.
There is an identification plate on the differential.
They were also sold with both 15" and 16" tires, which would act like a slight rear end change.
(i think the 3500 only had 16", but i'm not sure about that).
Let's see: 4.11/3.73 is a 10 percent change, and the shift from 16" to 15" is a 6 percent change.
