- 4.250in bolt circle and 2in female pilot
- 19 degree joint angle
Matching a yoke to the pinion
A flange yoke is the link between the driveshaft and the pinion, so its bolt circle, pilot and joint angle need to agree with the pinion flange. The U-joint series must also match the yoke. When those dimensions line up, the joint sits square and the driveline runs with less vibration.
Before assembly, clean both mating faces and check for burrs or nicks that would keep the flange from seating. Use fasteners that suit the flange and confirm they are the right length for the threaded holes. Inspect the yoke bore and pilot for wear if the part has been in service.
- Compare bolt circle and pilot with the pinion flange
- Clean and deburr both mating faces
- Use fasteners sized for the flange holes

Vehicle fitment
This yoke is universal fit and is not vehicle-specific. Its fit depends on the U-joint series and the pinion flange, not a vehicle model.
Check the bolt circle and pilot against your pinion flange. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Hardware is not included, and the yoke is set up for 12MM bolts, so confirm the bolt size against the flange before assembly.
