2004-2007 Cadillac CTS-V Performance Mods Discussion, Limited Slip ??? in Cadillac CTS-V Series Forum - 2004 - 2007; The V has a mechanical clutch type limited slip diff right? Not an electronic braking type. I'm not talking about ...
You are correct sir.
It has what I affectionately refer to as a G80 diff.
G80 is not listed on the SPID label of a V because it is part of another package that the V has, the base models all show G80 with limited slip if so equipped.
My Trailblazer has G80 but it is an Eaton locker which uses some quite different parts.
It has a flyweight and some gears in it to lock the rear end but the principle is the same.
