    How can you tell the difference between a GOV-lock, detroit, and a posi-track in a 14bff?

    Gov-loc, you will see the clutches showing through on the side of the carrier, it also has 3 spider gears so the crossshaft only has 3 legs, which you would see between the carrier, where the 2 halfs meet, around the ring gear, if its open or has a Detroit, there will be 4 legs. Also if it has a Detroit, look at the carrier on the side youll see a spring, if its open, youll just see the side gear. As for the posi trak, there isnt one. /forums/images/graemlins/thumb.gif

    There is no such thing as "posi-track" for the 14FF. Gov-lock and posi-track are often the same term for the other. When you get to younger kids who always talk about how their rig has posi front and rear, their term is generally "posi-track." The guy who knows a little more about his rearend will know they are Gov-locks for the GM axles.

    But like stated above, 3 pin spider gears are the Gov-lock and 4 pin spiders are open differentials which are what you need to upgrade to the Detroit Locker or other types of traction adding devices. /forums/images/graemlins/wink.gif
