This is the Team Integy Purple Aluminum Internal Differential Housing for the HPI Savage X, XL, 21, 25, SS, and 4.6 Series trucks.  This is much stronger than the stock internal diff case.  This will work on the front or rear of the truck.  If you would like to upgrade both the front and rear of the truck, purchase a quantity of "2" of these.  These are a must for high-performance trucks.  This is a great way to increase the durability of your truck.  This will help reduce the chances of complete differential failure.
