i sure see this a lot. Does it bother anyone?

Posi is short for "Positive traction" basically what every clutch or lock up differential does. Ya but we don't want to sound like a Chevy boy! LOL


sure grips me!![]()

Strictly speaking, a chevy term. Buick, olds, and pontiac all had special, and different, names for their limited slip diffs.I don't like Mopar guys using the term "POSI" period, but it's just a term most people use because it's easy to say & most car guys know what your talking about. It's STILL a GM term though.
