When fitting the P211913X, verify the companion flange bolt circle matches 4.25" and the pilot diameter is 3.125". The type F pilot registers on the face of the companion flange — confirm the pilot OD seats without interference before torquing fasteners. The 1330 series U-joint interface must also be confirmed against the driveshaft series.

The 1330 series sits one step above the 1310 in the SAE torque ladder and is used in medium-duty light truck and performance applications. The 4.25" bolt circle is larger than the 3.5" bolt circle used in 1310-series CV flanges (P211229X) — confirm the bolt circle of the companion flange before ordering the P211913X.

The P211913X does not include a lube fitting. At annual or mileage-based service intervals, inspect the ball socket and seat for wear and replace the CV assembly if binding or free play is detected. The 3.125" pilot diameter and 4.25" bolt circle are the two critical dimensions to verify against the companion flange.
