This is a full rebuild kit for the factory LSD with a few performance oriented differences.
This kit includes all internal clutch/friction plates and spline plates. Comes with a full set of new compression springs as well.
This is not a standard rebuild kit. This kit includes the extra thick outer clutch plates, extra thick spline plate, and a slightly thicker inner clutch plate.
This will have essentially the same effect as "shimming" a stock LSD. It will make the lock up characteristics firmer and more aggressive than a stock LSD.
