Which posi unit did Stude use in the '55-64 Dana 60?
by jack vines
My research indicates there are two main types of limited slip units for the old Dana 60. One is the Powr-Lok unit which has four pinions and two cross shafts. The other is a Twin-Trak which has two pinions and one cross shaft.
Just for information, there also exists a Detroit Locker unit which is more off-road/racing.
Has anyone ever had a Stude unit apart to confirm which was OEM?
