PTO CV Joint Assy, 80-Deg Cat 6 W2580-Series X 1-3/8"-6

PTO CV Joint Assy, 80-Deg Cat 6 W2580-Series X 1-3/8"-6, 51mm Star Shafting

The Weasler 15507951 PTO CV Joint Assembly is a heavy-duty, wide-angle constant velocity joint engineered for high-horsepower driveline applications where smooth, reliable power transfer is critical. Built for Category 6 PTO systems, it handles extreme operating angles up to 80° while maintaining consistent rotational speed—minimizing vibration, wear, and stress on your equipment. Designed with precision-machined steel components, it’s ready for demanding field conditions where straight lines are more of a suggestion than a reality.
