Heavy duty machined 7075 alloy differential case for the DR10 (NOT for the B6).

Perfect machined roundness makes for a free spinning transmission and a must have for high powered drag racing applications.

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.

This is for 1 diff case and 1 diff cover- DR10 gear diff parts are required.
