When working on a Ford Superduty transfer case, you might encounter a situation where the existing companion flange is worn or damaged, leading to vibrations or misalignment. The 3301-312 Companion Flange is the solution you need. It features dual threaded bolt patterns with an M12-1.75mm thread specification, ensuring a secure fit to the differential or transfer case.
This flange has a spline count of 31 and a spline diameter of 1.343 inches, which is critical for maintaining the integrity of the driveline. The hub diameter measures 1.812 inches, with a pilot diameter of 2.000 inches, allowing for precise alignment with the mating components.
