DANA -- 70 -- Information
 

I have a one ton DANA 70 rearend with a 4.56 gearset. I want to install a 3.70 gearset in it's place. Would anyone out there know what is required to do this change along with the parts that are needed. This DANA has the 9 or 10 bolt cover which i was told was the old style. Lets hear from the experts. --- Thankyou

Go to the website of randy's Ring and Pinion. They have everything you need to change gears.

You will be going past the split point for the carrier. ... You will need a different differential if you go numerically lower than 4.56 ... Tom
