Ford OEM 1.5 / 1.6 Ecoboost Rear Main Seal Retainer
Description
Description
The Ford Rear Main Seal Retainer (BM5Z-6K301-B) is an original factory component engineered for 1.5L and 1.6L EcoBoost engines. This retainer maintains precise alignment and sealing of the crankshaft’s rear main oil seal, protecting your engine from oil leaks and pressure loss.
Built using high-quality, heat-resistant OEM materials, the BM5Z-6K301-B securely retains the crankshaft seal in position under extreme temperature and pressure. It is the factory-recommended solution for preventing rear main seal movement and long-term oil leakage.
This part also replaces BE8Z-6K301-A and installs directly with no modifications required — perfect for those who value OEM reliability and factory precision.
