This Victor Reinz Crankshaft Seal is a direct-fit replacement for Porsche 928 applications from 1978–1987 listed in the fitment table below. This crankshaft sealing component helps control oil at a rotating shaft interface, where correct fit and sealing lip behavior are necessary to limit leakage over time.

Victor Reinz sealing components are made for the demanding surfaces and temperature swings found in European engines. With Dana’s OE background behind the brand, these parts are selected when fit, material quality, and sealing consistency matter during Porsche service work.
