Black vs Blue Tag ZF’s

Black Tag ZF’s were made from 1989 to mid 1993. Blue Tag ZF’s were made from mid 1993 to 1996. Black Tag ZF units were made in West Germany, by ZF. By 1993, GM was making them under license in the USA.

Complaints about gear whine on the Black Tag ZF led to the creation of the Blue Tags ZF units. These units were cut down on whining by cutting the gears at a steeper angle. This resulted in a marginally weaker box found on the Blue Tag ZF units. Overall, the Black Tag ZF has a 450 ft/lb rating, while the Blue Tag ZF has a 400 ft/lb rating.
