About 4103-344
The Ford 5R110W TorqShift transmission is found in 2003-2010 Super Duty F-250 through F-550 trucks with the 6.0L and 6.4L Power Stroke diesel engines -- one of the highest-torque light-heavy truck transmissions used in that era. The 10.150" C/U-joint to end dimension is among the longest in the 1410 series lineup, reflecting the extended slip travel needed on long-wheelbase Super Duty trucks.
The 2.300" hub diameter is specific to the 5R110W tail housing output seal. Using a yoke with an incorrect hub diameter on this transmission will result in immediate fluid leakage that contaminates the driveshaft and differential. No counterbore is used -- the output shaft engagement centers the yoke. Cross-reference with Spicer 3-3-4381X for an OEM-matched alternative. Inspect the output shaft for scoring before installation.
