The pinion yokes are designed to properly align the pinion gear with the spool, ensuring smooth operation and reducing the risk of gear wear. The U-joint is designed to provide flexible yet strong connections between the axle shaft and the differential, promoting smooth operation and minimizing vibrations.

The Big Gen3 Pro SFI differential is also equipped with a set of high-quality seals and gaskets. These seals and gaskets are designed to prevent leakage and maintain proper lubrication, ensuring the long-term performance and reliability of the differential.
