Dana Spicer 2-2-1679 1310 Series Flange Yoke
The Dana Spicer 2-2-1679 Flange Yoke is a genuine Spicer driveline component designed for 1310 Series universal joint applications. Built from durable steel and manufactured to Dana Spicer specifications, this flange yoke provides a precise connection between the driveshaft and mating flange while maintaining proper driveline alignment and torque transfer.
The 2-2-1679 uses a square four-bolt flange pattern with a 3.344-inch bolt circle, 0.406-inch drilled bolt holes, and a 1.812-inch male pilot. It is designed for a 1310 Series outside-snap-ring universal joint with a 1.062-inch bearing cap diameter and approximately 3.219-inch U-joint width. The distance from the flange face to the U-joint centerline is approximately 1.770 inches.
This flange configuration is commonly associated with select Toyota driveline applications. Because similar flange yokes may use different bolt patterns, pilots, offsets, or U-joint dimensions, the existing flange should be measured carefully before replacement.

Fitment Note
The Dana 2-2-1679 uses a square, equally spaced four-hole pattern. Similar-looking Toyota flange yokes are available with rectangular bolt patterns and are not necessarily interchangeable. Before ordering, verify the 3.344-inch bolt circle, 0.406-inch bolt holes, 1.812-inch male pilot, and 1310 Series U-joint dimensions.
