Description

2-2-489 UDS 1330 Flange Yoke
The 2-2-489 is a 1330 series flange yoke manufactured by UDS. It bolts to a companion flange on the transmission, transfer case, or differential output using a 4-bolt pattern on a 3.750-inch bolt circle. The 2.750,-inch pilot diameter registers the yoke concentrically against the companion flange to minimize runout.
The 4 bolt holes are 0.438-inch diameter on the 3.750-inch bolt circle. The center-U-joint-to-flange-face dimension is 1.562 inches. This 1330 series yoke accepts a 1330 U-joint in the yoke ears — the ear bore is machined specifically for the 1330 cap diameter. Application note: REQUIRES A 1330 SERIES UNIVERSAL JOINT. The 1330 series ranks above 1310 in torque capacity, with a 1.062-inch cap diameter, suited for 3/4-ton trucks and heavier light-duty applications.

Fitment & Installation Notes
Before ordering the 2-2-489, measure the bolt circle diameter and pilot diameter on the companion flange. The bolt circle (3.750") and pilot (2.750,") must match exactly. A 1330 U-joint is required — do not install a different-series joint in these ears.
