Locker Identification Request:

I just picked up a set of axles and for the condition they were in on the outside I was very surprised to find lockers that look to have never been run on the inside of both the front and the rear. Neither seem to have a manufacturer that I could identify. If you know who made this I would very much appreciate finding out. View attachment 54847 View attachment 54847

 

looks right a lockright. designed to go inside an open carrier.

 

spool
Yukon Gear & Axle Spool for Jeep Wrangler TJ (Non-Rubicon), CJ & XJ Dana 44 Rear w/ 30 Spline Axle


Edit. I know its not a spool... I was linking a spool so that people could understand what one was via picture if they did not. It's clearly a lunchbox locker.

 

it is not a spool. it is a lockright locker made by powertrak. it is designed to go inside a gutted open differential carrier. it gives you a locker without having to setup the gears.

 

Lunch box locker. A spool permanently locks the wheels together with no give. A lunch box lock will "unlock" when no torque is applied to the cross pin, like when coasting around a corner.

This is a very good video explaining how these work. The one I used to have in the rear of my 55 chevy didn't ratchet though, made more of clanking and banging noises and people would give me funny looks.

 

And a shorter video with a spartan.

 

Judging by the housing shape, I think that is an AMC 20 rear axle. Not really desirable unless they have allot of work done to them.
Your gear Ratio is 3.54 and it looks like drop in locker to me.
