Exotek B6.3 heavy duty 7075 alloy diff case

From Exotek comes this heavy duty machined 7075 alloy differential case for the B6.3 & B6.2. Perfect machined roundness makes for a free spinning transmission and a must have for high powered drag racing applications and extra internal machining allows for extra fluid to be added for increased fluid capacity and life. This is much stronger than the stock plastic diff gear but not indestructible so it is important to use black or white grease on the gears and reapply frequently to prolong its life.
