From my sons dirt track car with a 9 inch ford, they make a seal that slides in the axle tube to keep lube in the center section don't know if they make them for any thing else.I have been told that most major nascar teams have a diff dyno to run there gears on. Was told that it takes 47 hp to get a 9 inch up to speed and then 3 hp to keep it at speed. With that being said any thing that we can do to make less drag in the diff, the car should go faster. Most of us run small motors 350s or less and what some 500 plus does not apply to us. Tom
