Saddle up with the Teutuls for more awesome OCC action from Season 3 in this 3-disc set. Follow the day-to-day drama of this volatile father and son team as they battle impossible deadlines - and each other - to push the envelope of motorcycle design and fabrication. Building on his previous two spider-themed choppers, Junior takes on a third arachnid-inspired project, challenging himself to create the most outrageous bike to date. Junior and Senior then join forces to build two custom choppers that will be auctioned off to benefit the families of U.S. troops seriously wounded or killed in Iraq and Afghanistan. Meanwhile the boys from OCC get an out-of-this-world experience when they visit NASA, seeking inspiration for a Space Shuttle Tribute Bike.
