Rear Crankshaft Seal

Product Details

When refreshing your drivetrain or completing clutch and flywheel service, replacing the transmission-side crankshaft radial seal is an absolute requirement for long-term engine health. A leaking rear main seal allows high-pressure engine oil to seep past the crankshaft journal, messily coating the bellhousing and ruining clutch friction material. Febi Bilstein offers this OE-quality replacement rear main shaft seal designed to handle high RPMs, extreme engine heat, and harsh synthetic oil environments. Molded from a premium FPM and PTFE compound, it creates an airtight, low-friction seal around the crank journal. This unit arrives complete with a plastic installation tool sleeve to guarantee proper lip alignment and prevent tearing on the crankshaft keyway during installation.
