3102-9000 – Flange Yokes – 1310 Series – Bolt Hole Dia 0.000″ – Pilot Dia 1.850, F

Understanding the 3102-9000 Flange Yoke -- 1310 Series Application

Not every driveshaft terminates at a slip yoke. Many factory and performance builds use a bolted companion flange at one or both ends, and the 3102-9000 is the correct 1310 series yoke for those configurations. It presents a N/A-bolt pattern on a 0" bolt circle with 0.000" bolt holes and a 1.850" female (recessed) pilot, covering the dimensional requirements for a broad range of OEM and custom companion flanges.

Specification Summary

Series Ratings and Torque Capacity

Series 1310 represents a specific u-joint cross size and load rating. Running a mismatched series component downstream of a 1310 u-joint creates an unbalanced failure point -- the weakest link defines when and where the drivetrain breaks. The 3102-9000 is designed as a native 1310 series component, so the cap bores match the cross dimensions and the torque path remains consistent from u-joint to flange face.

Assembly Guidance

• Seat the 1.850" pilot fully before torquing -- do not rely on bolts to draw the yoke into alignment
• Distribute bolt load evenly through at least three torque passes
• Apply thread-locking compound on fasteners exposed to vibration (off-road, high-RPM)
• After initial drive, re-check bolt torque -- new joints settle slightly during first use
• CJ-to-flat dimension of 1.570" must clear u-joint lock ring or snap ring groove

Ordering Confidence

If you have confirmed that your companion flange has a 0" bolt circle, 0.000" bolt holes, and a 1.850" pilot bore (F), the 3102-9000 is the direct match. Universal Driveshafts stocks this part for immediate dispatch to get your vehicle back in service without delays.
