I read reign's statement to apply to all F250s, which just isn't so. Yes the snowfighters and crew cabs had the D60 for two years. Now try to find one still in existence. Generally speaking nobody should expect to find a Dana 60 under an F250. Chances are better to get a winning lotto ticket.

The Dana 50 goes back to 1980 with the introduction of the Twin Traction Beam front suspension.
