Product Details

SKF has a long history in shaft seal engineering, beginning with the first integrated shaft seal design in 1928. This transfer case seal is manufactured to specific design requirements using premium materials selected for the operating environment, helping keep lubricant inside the transfer case and contaminants outside. The 19641 seal is a practical choice for service work on Nissan Frontier, Pathfinder, Xterra, Pickup, and D21 models where the transfer case seal needs replacement.

This part cross-references Nissan 33111ZD30A for the same application.
