Title: Is this a locker, a posi, a standard open?
Post by: cboss70 on January 17, 2024, 04:57:27 PM
I recently had cobra auto remove what I thought was a locker with 4:11's from a 66 Shelby rearend (and I think they agreed) and had them put the original stuff back in. I figured I'd list it for sale on CL to get some funds back and based on these pictures a person told me it was a standard carrier. I don't want to mislead anyone. Can anyone confirm for me based on these pictures?

This is what the guy on CR emailed me: The Posi unit has beefy and deep cut bolt holes on the side. If your carrier was a posi of any kind, it would have similar beefiness and depth and yours does not have that. I don't think it's a locker. I doubt I'm wrong.

What you have shown isn't much help. The limited slip will have springs and clutches. The Detroit locker you can see right through where the axles go since they don't have a shaft or side gears. Look in the red area for the clutches.

What you have looks like a Detroit Locker to me. It's NOT a standard carrier. What the Craigslist responder is describing is a Ford Traction Lok unit. These have the "beefy and deep cut bolt holes on the side" because that's where the clutch pack is on the inside of.

Did your car clunk and lurch when making turns? If so it's a Detroit locker.

Based on this picture and what you are saying it looks like a locker- you can see straight through. I learn something new every day- thanks for all the pointers.

     Yes, that 'IS' a Detroit Locker unit.   ;)
