1935 DODGE PICKUP HIGHER SPEED REAR END

[lwillmarth]

Does anyone know if I can change the ring & pinon in a 1935 Dodge pickup to get better mileage and so the engine does not turn so fast? If so, where could I locate these gears? Thank you

The best ratio you might find is 3.70 that was used in some of the Mopar coupes. The 4.13 was basically the standard in most cars/trucks from the 30's - early 50's. Even with that, you are only changing by 10%. Instead of cruising at 50 MPH as it was designed, you can now do 55 MPH at the same RPM.
