3.73 and posi
I have a 12 bolt posi that I will not be using. I was told it was rebuilt with stronger springs when I bought it. It has 3.73 gears with it (cant remeber which series that makes it). Looking to get what I paid for it $375 with gears $350 with out.

Re: 3.73 and posi
Guess that would help it is all stock gm parts. I'm open to offers. It is just taking up room on the shelf.

Re: 3.73 and posi
Are you sure it's for a truck and not a car 12 bolt?

Re: 3.73 and posi
I do not have any documentation of the rebuild, only the mans word that it had been done. I am almost certain it is for a truck but if you can tell me the difference Ill double check.

Re: 3.73 and posi
Does the posi carrier have the window like you took the photo of the springs through on one side or both? What is the diameter of the pinion shaft? What is rhe nber stamped on the carrier housing? How many splines are on the axle housing? These details will tell if its for a car or truck.

Re: 3.73 and posi
Yes any will fit. They are just for different ratio ranges.

Re: 3.73 and posi
Looks like 41 teeth on the ring and 10 teeth on the pinion. Wouldn't that make it a 4:10 ratio?
