The team chase drive cups are a direct replacement for the stock cups. The goal was to make a drive cup that will last longer than the differential, the bearings, diff oil, and most likely the truck. After months of testing, racing, and just beating the cups tank after tank we are happy with the results.
Team Chase cups have gone through a multi step heat treating process to result in a material that is far superior to the stock drive cups.
