This was in my red car when I bought it. I didn't have a need for 4.10's at the time so I traded the whole rearend for another rear end and other things to a buddy of mine. I recently bought his car and am going to put the rearend into my 88GT. Only thing is it's been so long since I bought the car I forgot what kind of traction loc this is, middle age sucks at times.

It's similar to the Ford trac-loc but better IMO the plate and spring set in the center do a better job than Ford's "S" spring setup.

Dave, that looks a lot like what the previous owner put in my diff.  He claimed it was a Auburn Pro Limited Slip diff.

Mine is an Eaton

If I saw that thing in my rear view Im pulling over to let you by, I be scared of that thing Huh? i dont know wich car is uglier ur or mine?

Ugly?  Easy now -- that's my baby and it's got lots of unique character!  When I drop that built 445" stroker in it you won't have any time to "pull over to let me pass" because I'll have already blown past you when you figure out what the hell was that loud noise behind you . . .

Is there a consensus of these being good or not? Obviously I'm going to run it because I have it, just curious of their longevity/reliability.
