The 3501-291 is a crucial component for Chrysler 9.25 differentials, specifically designed to ensure a secure connection between the differential and the driveshaft. This Companion Flange features a bolt circle diameter of 3.937 inches, providing a robust interface for mounting. With 29 splines and a spline diameter of 1.263 inches, it effectively handles the torque and rotational forces typical in these driveline setups.
When installing the 3501-291, it’s essential to ensure that the flange face is perpendicular to the rotational axis. Any runout can lead to vibrations, which can cause premature wear on associated components. Proper installation involves cleaning the mating surfaces and torquing the bolts in a star pattern to achieve even pressure across the flange.
