This unit bolts to the PTO flange. Used for heavy duty jet H-bar for 600 horsepower and up. Note: The overall length does not include the PTO flange which is and additional one inch thick.
Driveshaft itself is nice! Huge, should handle HP.
Just dont go making a Custom PTO using the bolt pattern listed, its not right. I had to pay to make 2 of them & send the end of the driceshaft. Other than that driveline looks strong. Will put it soon and see how it handles 700hp
