Are drive shafts normally hollow?
Car and truck ones are. Most racers with slick tires will upgrade the U joints and driveshafts to a beefier stronger aluminum unit. My Mustang twisted one the second time out at the dragstrip with slicks on. The first time it sheared off the lug nut bolts clean at launch and I got to watch my back tire roll by me as the car sat cockeyed on the finish line. Carbon fiber is also a good choice but expensive.
