demanding conditions part no lube do i need pro gears pro gears can be used in vehicles that are for drag race only they are not suitable for street-strip vehicles 1 if the drag vehicle has a manual transmission a pro gear is generally used 2 if the drag vehicle has a transmission brake a pro gear is needed 3 if the drag vehicle generates 600-700 horsepower a pro gear is needed 4 if the drag vehicle has tires that are 15 or wider a pro gear is needed 5 if the drag vehicle is at or over 3,500 lbs a pro gear is needed 6 if the drag vehicle consistently breaks a street gear a pro gear is needed 7 if the drag racer wants more security and dependability in the drivetrain 8 if the drag racer wants to win pro light gears have become very popular because weight is removed from the back of
