3301-000 – Companion Flanges – 1.401″ Splines Dia – 2.125″ Hub Dia – 32 Spline

The 3301-000 companion flange is a critical component for those building a rear CV shaft compatible with the 203 or 205 transfer cases. This flange stands out due to its unique specifications, making it suitable for custom applications. With a spline count of 32 and a spline diameter of 1.401 inches, it provides a robust connection that ensures reliable torque transfer.

Measuring a hub diameter of 2.125 inches and a pilot diameter of 1.808 inches, the 3301-000 is designed for precision fitment. The through hole measures 2.000 inches, allowing for easy installation and alignment. Notably, this flange features a blank bolt circle diameter, which means it can be machined to meet specific requirements, giving you flexibility in your builds.

When installing the 3301-000, ensure that the mating surfaces are clean and that you torque the bolts in a star pattern to maintain even pressure. Additionally, checking the face runout is crucial to prevent vibrations during operation. Here are some key points to consider:

• 32 splines for secure engagement
• 1.401″ spline diameter for compatibility
• 2.125″ hub diameter for a solid connection
• Blank bolt circle for custom machining
• 5.475 OD for specific applications

In summary, the 3301-000 companion flange is engineered for performance and adaptability, making it an essential choice for any driveline project.
