"To support the greater horsepower and channel it to the ground durably, the engineers borrowed some heavy-duty, proven parts from the Gen 6 Camaro ZL1 including the half-shafts and prop shaft and the beefier Gen 5 ZL1 and Chevrolet Performance driveline upgrade with a 250mm, 3.73-geared rear-axle center section. They nicknamed it “Gravedigger,” because they haven’t been able to break it. The parts might be included in a range of Gen Six Camaro drag-racing parts Chevrolet is evaluating."
