I went to the Raptor Assault Class March 15 & 16. The instructors said that the Raptors were stock except for the graphics. I noticed that all the Raptor Assault trucks had the Ford Performance differential cover on the rear differentials. I asked one of the instructors why they had the diif covers and he said he didn't know but he would find out. He went and asked another instructors and came back and said they install them because they hold 1/2 quart more fluid. I will be installing one on my truck this week.
