STronger than the Delrin diff but still a part that wears out.
lighter than conventional steel diff out drives
Wear on the universal dog bone part. The pins dig into the aluminum over time.
If you use the plastic blades the diff out drives will last longer. Again based on the cost vs wear rate... the Metal diff is the way to go for the front.
The Delrin part wears much better and has less stress on both the delrin diff joint, and the universal drive shaft pin.
Great for looks but functionality is ok.
