    Stands to reason. With 4.88 gears and running the 1/8th mile a lesser driveshaft will more likely survive longer than if it were taken to a 1/4 mile track and turned higher RPM. I've always wanted to put a high speed camera under a truck with a 4' or longer driveshaft running large number gears and pushing real power. I bet that driveshaft grows 6" larger in diameter by the time they hit the end of the quarter.
