This graph was generated by an independent testing facility. It demonstrates the amount of torque it takes to break a Longfield 30-spline Super Axle as well as a standard 35-spline Dana 60 axleshaft. Note how close the breaking point of the Longfield is to the Dana 60s. Keep in mind that the Longfield short shaft failed before the joint itself did. These are some tough Birfields!
