Dana / Spicer 3-2-939 Flange Yoke – 1310 Series Driveshaft Flange Yoke
The Dana / Spicer 3-2-939 Flange Yoke is a precision-engineered driveline component designed for 1310 Series driveshaft applications. This flange yoke provides the connection point between the driveshaft and the transmission, transfer case, or differential flange, allowing torque to be transferred efficiently through the vehicle driveline.
Manufactured by Spicer (Dana), the 3-2-939 is built to OEM specifications using high-strength steel construction and precision machining processes to ensure proper universal joint fitment, driveline balance, and long-term durability. Flange yokes are critical drivetrain components because they must withstand continuous torque loading, vibration, acceleration forces, and changes in driveline angles during vehicle operation.
The Dana / Spicer 3-2-939 is commonly used in light- and medium-duty truck, 4×4, and commercial vehicle driveshaft applications requiring a 1310 Series universal joint connection. It features a square flange design, four bolt mounting pattern, and precision-machined bearing surfaces for proper U-joint operation.
