Full Description
Production-Grade 1310 Series Flange Yoke -- Part 3102-409X
Custom driveshaft builders and OEM repair technicians share the same requirement: a flange yoke that matches the companion flange exactly and survives the duty cycle of the vehicle. The 3102-409X meets both criteria. Produced in 1310 series geometry with a 3.543" bolt circle and 4.094" pilot, it fits the companion flanges found on a wide range of trucks, SUVs, and performance vehicles without secondary machining or shimming.

Companion Flange Compatibility Logic
A companion flange is defined by four measurements: bolt circle diameter, bolt hole count, bolt hole diameter, and pilot bore diameter. The 3102-409X is designed around 3.543" BCD, 8 holes at 0.325", and a 4.094" pilot. If all four of your companion flange dimensions match these values, the 3102-409X installs without modification. Cross-reference your existing yoke or the companion flange directly -- do not rely on vehicle year/make/model alone, as suppliers changed flange specs during production runs.
Step-by-Step Fit Verification
- Measure the bolt circle diameter on your companion flange -- needs to be 3.543"
- Count and measure bolt holes -- 8 holes at 0.325"
- Measure pilot bore -- must accept 4.094" pilot
- Confirm 1310 series u-joint is already installed or on order for the same build
- Verify CJ-to-flat (2.750") will not cause cross interference with companion flange recess
Universal Driveshafts has stocked the 3102-409X as a catalog item because the 3.543" bolt circle, 1310 series configuration is a common spec across numerous platforms. Order with confidence -- this part ships from stock.
