FAG SS2961 Transfer Case Output Shaft Seal - Front

Transfer Case Output Shaft Seal for GM Applications

The FAG SS2961 transfer case output shaft seal is built for specific Chevrolet and GMC driveline applications that need reliable sealing at the transfer case. It uses a polyacrylate sealing material with a rubber spring and auxiliary lip design to help keep contamination out and retain lubricant at the seal interface.

For Chevrolet C3500, K3500, Astro, S10, P30, and GMC K3500 and Safari applications, this seal is sized to match the listed bore and outside diameter requirements. The FAG SS2961 is a direct-fit sealing component for transfer case service where correct dimensions and seal construction matter.

Installation Notes and Tips

Verify the transfer case type, position, and seal dimensions before installation. Match the bore diameter, outside diameter, and width to the original part specification, especially on Borg Warner 1370, 4470, and 4472 transfer case applications. Clean the sealing surface thoroughly and inspect the shaft for wear or scoring before installing the new seal.
