9 1/2″ Pro Gears will provide much longer gear life in comparison to 9″ Pro Gears
Life expectancy can increase by up to three times depending on the vehicle
The exception is when there is violent tire shake and the vehicle is kept under power.
The ring gear is manufactured to 9 1/2″ specifications before the OD is reduced to 9.25″
Resulting in a much stronger tooth design than possible with 9″ Pro Gears.
