HELP I got a 14 bolt the other day. Pulled the cover and looked inside to see a traction device of some kind. Does anyone have a pic of the gov lock or other posi / lockers so I can ID this one?

Well that would be taking the easy track now wouldn't it!
I don't have a digital camera and I'm at work. I can discribe it however...more or less. Pretty much a solid cone shape coming thru the ring gear.....
 
Yeah...I think your right.....no one likes gov. locks? is it a locker or a posi?
 
They have a bad rep because they are crap in the 10 and 12 bolts. They are more durable in the 14BFF. They are not a real "reliable" locker though. They use wheel speed to lock up, and sometimes they don't, and sometimes they do at the wrong time ie. one tire moving at 35mph then lock then boom:laugh: If you want to run a Detroit you'll need a new carrier as pictured above with 4 cross pins. If you just need traction, and don't mind driving it on the street weld up the gov-lock:D
 
more like a LS as far as I know, def. not a true LOCKER. but run it til it dies, better than open I would guess.
 
Do I need to add any friction modifier to the diff? or just straight 80/90?

no additives needed.

YOu sure about that? Not everyone uses the proper additive....but im pretty sure it makes a big difference in how well it works.....There is an additive you are supposed to use for a reason.
 
Friction modifier is spec'd by GM. Usually you don't need it though... because the clutches are already worn out. :haha:
