In addition to a slew of rear Dana 80s, Custom Diff says that they've built several of these custom front Dana 80s over the years. This specific axle was made from a Dodge dual rear wheel application. It can be used either in the front of a vehicle or in the rear where rear steer is desired. They were able to machine the factory axletubes to accept Chevy Dana 60 outers. This specific axle is unique in that it has adjustable knuckles. Custom Diff installed adjustable flanges (pressed and then welded) that allow the knuckles to be rotated to compensate for changes in pinion angle. This means the alignment of the axle remains intact, no matter how much the axle is rotated.
