I have a Dana 80 in my truck with 4.30s and a Detroit. I want to put 3.55s in. What I want to know is there a way to make my Carrier that is for 3.73s and up work with 3.55s. I would just buy a new one but I have a Detroit Locker and they dont make one for 3.55s.

 

Why not make life simpler and settle for the 3.73? Its a good jump from the 4.30.

BTW I *need* to know where you find stock trucks knocking on 600 hp's door

 

Im going to go run stock height so a 33 inch tall tire will be used and I want to keep the rpms low on the freeway. It is all stock.......Stock diesel performance items that is
