    traction wise I don't think so but they don't have the reputation of exploding like a gov-lok

    If you are in need of a fully locking diff than the P/L will disapoint you BUT if you want a true to life limited slip type diff than the P/L is the most aggressive clutch type diff offered for Dana axles.
    A lot of folks that complain about P/L's are either at full hard core truck status or have been using a P/L that is already wore out and needs rebuilding. They are very good and STRONG units !

    the powr-loc in my dana 60 is 35 yrs old and still going strong. They can be rebuilt and additional clutches can be added to tighten it up. This is per the dana60/70 powr-loc manual I have. They reccomend 3 clutches per side for front applications and 5 clutches per side for rear applications.

    Well, not quite.

    On the D70, each side of the side gears require 3 clutches and 2 plates. Should have 6 clutches and 4 plates in the whole shebang. :waytogo:

    As I understand it, the main advantage of the Power Lock over the Trac Loc can be seen in the "apart" view of Wes's ebay link. It has FOUR spider gears, while the Trac Loc only has 2.

    The extra 2 spiders are a minor detail. The major difference is how aggressive it is. The Trac-lock relies only on the spreading force created from spiders turning to compress the clutches. The Powr-lock has 'ramps' for the crosspins to wedge against and apply more force to the cutches.

    The Powr-lock is a very heavy duty and aggressive limited slip. It is revered by many as the ultimate traction device to use in a front axle application.
