Product Information

Differential Input Shaft Seal – 50x80x9
This heavy-duty input shaft seal from Corteco is designed to replace the original pinion seal on BMW differentials. It measures 50x80x9 mm and helps ensure leak-free operation at the front of the differential housing.

Factory seals are prone to leakage due to their high-friction design and insufficient lubrication over time. This upgraded Corteco seal was developed to address these issues, featuring a large primary sealing surface and dual secondary exclusion lips for improved contamination resistance and long-term reliability.

Recommended: Replace the lock plate (part #33121205138) during installation for proper retention.
