two speed rear?

[mv7fd]

i have a 2002 f250 right now its an automatic i'm going to switch it over to the speed speed that is all fine to do but is it possible to work a 2 speed rear into the works is it even worth doing and how would i do it

Its America, you can do anything you want. I don't think you gonna gain much by doing this though. By the time you are pulling enough weight to justify the rear, you will be way over weight.

If you doing it for the cool factor then, yeah you can do it. You just need to figure out how to drive the speedometer cause it is driven off the rear axle.

Are you talking about tandem axles and having both drive, or actually a two speed rear diff ? Using the sterling 10.50 I'm not sure if you can accomplish the second you may need to upsize . Some of the eaton diffs that come in the newer 450 and up may have some options and you may need to swap one in

if your going with the first ive seen a guy do it . He got to work by placing a divorced np205 backwards ( transmission input connecting to the rear output of the case , the front input of the case going to rear diff , and the front output going to the front rear diff . It was hokey but worked

Just for the cool factor and I'm talking about a two speed diff so in theory I'd have 12 gears
