Description
The 2-1-1313-4 Companion Flange is a critical component in your driveline assembly, ensuring proper alignment and reducing vibration. This flange bolts directly to the differential, transfer case, or transmission output, providing a reliable connection to yokes or other flanges. With a pilot diameter of 2.375″ and a bore diameter of 1.250″, it’s designed to fit seamlessly into various configurations.
When installing the 2-1-1313-4, attention to detail is paramount. The flange face must be perfectly perpendicular to the rotational axis; any runout can lead to unwanted vibrations that affect performance and longevity. To ensure a solid installation, clean all mating surfaces thoroughly and torque the bolts in a star pattern for even pressure distribution. After installation, checking the face runout is crucial to confirm that everything is aligned correctly.
