Full Description
3102-86 -- Forged Flange Yoke for 1310 Series Drivetrain Systems
The choice between a slip yoke and a flange yoke is not cosmetic -- it defines how the driveshaft is supported and serviced at that end. The 3102-86 is the flange yoke solution for 1310 series builds, providing a rigid, bolt-on interface with a 3.935" pilot and 6-bolt pattern on a 3.386" bolt circle with 0.328" bolt holes. It eliminates the axial float of a slip yoke, making it the right choice for front driveshafts, short shafts, and any application where positive axial location is required.

Forged Steel Advantages
Cast yokes fracture along crystal boundaries under shock load. Forged yokes, including the 3102-86, have aligned grain structure that absorbs impact and distributes stress rather than concentrating it. In off-road, heavy towing, and performance applications, this is the difference between a yoke that survives a jolt and one that does not. The material is carbon steel, processed to the hardness range specified for 1310 series operating conditions.
Measurement Verification Steps
- Use calipers to confirm companion flange bolt circle is 3.386" PCD -- not nominal, actual measured
- Count bolt holes on companion flange and match to the 6 holes on this yoke
- Check pilot diameter: companion flange must accept a 3.935" pilot
- Measure CJ-to-flat on existing yoke; 2.750" is the value to match
- Confirm ear bore size is correct for your 1310 series u-joint cross kit
Direct Replacement and Custom Builds
The 3102-86 ships ready to bolt on. No secondary machining is required for standard companion flanges matching the above specs. For custom driveshaft builders, it offers a predictable starting point with known dimensions, allowing the rest of the shaft to be designed around a confirmed flange interface. In stock at Universal Driveshafts for fast dispatch.
