Description
The 1301-232 Companion Flange serves as a critical connection point between the axle assembly and the driveshaft. This component is specifically designed to fit applications using the 2352-1001 (plunge) setup, ensuring that the bolt pattern and pilot diameter match exactly for reliable performance. The flange features a bolt circle diameter of 3.386 inches, a hub diameter of 1.495 inches, and a pilot diameter of 3.937 inches, which are essential dimensions for proper alignment and function.
One of the key engineering considerations for the 1301-232 is the need for precise mating surfaces. The flange face must be perpendicular to the rotational axis to prevent runout, which can lead to vibrations and premature wear in the driveline. When installing, it’s crucial to clean all mating surfaces thoroughly and torque the bolts in a star pattern to ensure even pressure distribution.
- Bolt Circle Dia: 3.386 inches
- Hub Dia: 1.495 inches
- Pilot Dia: 3.937 inches
- Splines Count: 23
- Through Hole: 1.540 inches
By adhering to these specifications, the 1301-232 flange maintains its structural integrity under load, making it a reliable choice for both fabrication shops and performance builders. Proper installation and maintenance are key to maximizing the lifespan of this component and ensuring optimal driveline performance.
