Yoke
Mack

The Yoke is a precision-machined driveline component that interfaces with the U-joint to transfer torque from the transmission to the drive shaft. Its robust geometry supports high-torque applications while maintaining true alignment, minimizing vibration and wear on connected U-joint cups. The splined or square-end interfaces ensure a secure, repeatable mating surface, reducing the risk of loosening under heavy loads or rapid accelerations. Material selection and heat treatment are optimized for fatigue resistance, allowing reliable service across numerous miles and extreme temperature cycles. A quality yoke like this improves driveline efficiency, smoothness, and overall vehicle performance by preserving proper phasing and minimizing driveline lash. Regular inspection and proper torque when securing it help maintain driveline integrity. Source One Parts Center.
