As above, I see the catalogs seems to say lunch box lockers are not made to replace trac-locks.
It seems very cost effective versus 1 or 2 rebuilds.
Does anyone know why no locker for trac-lock?
Are there 1 or 2 pieces I could replace along the way to make it possible?

 

Trac-lok is already limited slip, and the housing is substantially different than the open diff the 'lunchbox' fellers are designed for. The trac-lok should be good for a hundred thousand miles or more, if properly taken care of. (and the funky little clips don't break.... which they always do.... rumor has it that there are 'second design' clips available, that are much better though.)
