Description
2-2-939 1310 series flange yoke for Ford 8.8″ and 7.5″ small bolt pattern, 4 holes x 0.500″ diameter, 3.500″ bolt circle, 2.000″ pilot.
Full Description
Ford 8.8" and 7.5" differentials are among the most commonly swapped rear axles in the domestic performance market. The small bolt pattern (3.500" BC, 4 x 0.500" holes) on this yoke is specific to the smaller-flange companion flanges found on stock 8.8" and 7.5" axles -- do not confuse it with the larger bolt pattern used on some performance aftermarket 8.8" builds.
- Series: 1310 -- 1.062" U-joint cap diameter; appropriate for street and light performance applications with the Ford 8.8"
- Bolt circle: 3.500" -- confirm the companion flange on the differential pinion matches this BC before ordering
- Pilot diameter: 2.000-F (female pilot) -- the 2.000" pilot bore on this yoke must register over a matching male pilot on the companion flange
- C/joint to flat: 1.650" -- use when calculating compressed driveshaft length at ride height
- Grade 8 (SAE) or 10.9 (metric equivalent) bolts required at the flange face
When upgrading from a 1310 to a 1330 or 1350 series driveshaft on a Ford 8.8" application, the companion flange on the differential must also be upgraded -- the bolt pattern and pilot diameter remain the same, but the U-joint ear bore changes with the series. The flange yoke and companion flange must always be a matched series pair.
