Dana Spicer 2-2-1379 1310-Series Drive Shaft Flange Yoke

The Dana Spicer 2-2-1379 Flange Yoke is a genuine Spicer driveshaft component designed to connect a 1310-series universal joint to a compatible four-bolt companion flange. It is commonly cataloged as a flange-adapter yoke for select Ford 8.8-inch truck axle applications using the larger bolt pattern. Its rectangular steel construction provides the strength and dimensional accuracy needed to transfer torque while maintaining proper driveshaft alignment.

The 2-2-1379 uses four equally spaced drilled mounting holes on a 4.250-inch bolt circle, a 2.000-inch female pilot, and a through-hole in the center of the flange. The yoke accepts a 1310-series U-joint with 1.062-inch bearing caps and is designed for outside-snap-ring-style joint retention.

Full Round Journal Design: Offers enhanced strength and fatigue resistance versus half-round styles.
Forged Steel Construction: Ensures long-term durability under heavy load and high-stress conditions.
Precision Machining: Guarantees a tight, secure fit within driveline assemblies.
Corrosion-Resistant Finish: Built to withstand harsh environmental and working conditions.
OEM-Grade Quality: Meets or exceeds original equipment manufacturer specifications.
