I didnt use silicon lube for the K diff. Silicon lube will help to eat up the gear faster. Besides, those silicon base lube runs around and will get into the clutch chamber quickly and the clutch will become useless. Instead, I use some kind of antiwear lube such as Racer's choice Hyspin plus. Due to the tight gear mesh inside the new diff case, the whole unit will act like having #5000 silicon diff lube. For more detail, check with AH10 as he is having great result with this combination.
