Need help identifying

[prib]

I am not knowledgeable on being able to identify the correct terminology for a 3rd member I have for sale. 489 case, new professional rebuild, 3.73 Moser gears new,came with a car that had been for running at the strip what do I have?

That will fit all the 8 3/4 axle housings. It appears that it utilizes U-bolt style U-joint retainers.

Also looks like the Chrysler/Dana Sure grip that is a clutch type.
We called them V-Ramp back in the day because the torque when applied causes the clutch pack to tighten.
Way better than the cone type that came after.
Prices vary from $650 to as much as $1,000 for a complete unit my guess. They vary allot.
3.73 is a good ratio for spirited drivers.

Thanks Darter6 I was told it is a spool hub??? originally, acts like something you want at the drag strip and this car had been used for that, inside wheel hops when turning, just not what I want unfortunately

Definitely a chrysler suregrip and not a spool. Maybe they shimmed the clutches tight

Just my opinion, it looks like a Detroit (or other brand, grizzley?) locker to me.
A new 8 3/4 locker alone is around $800.
As said above, it is certainly NOT a spool.

Not a locker, as Remcharger said clutch style suregrip.... Set up very tight...And it didn't need to be, the ramps cause it to grab very effectively... But when not loaded it releases and turns corners without spinning the inside wheel
