Full Description
The 6-40-521 Stub & Midship Shaft is engineered to deliver reliable torque transmission in demanding environments. With a unique configuration of 16 X 2.500 splines, this shaft fits specific applications where precision and strength are critical. The 3.734" butt diameter ensures a robust connection, while the 10.562" end-to-weld length provides the necessary fitment for various setups.

Using a shaft with the wrong spline configuration can lead to improper fitment, resulting in potential failure or excessive wear. The 4.000" tube diameter with a wall thickness of 0.134" further enhances the shaft's durability, making it suitable for heavy-duty applications.
