Description
Are you replacing a leaking rear main seal? The MAHLE Rear Main Crankshaft Seal is a direct-fit OE-quality replacement designed to seal the rear of the crankshaft where it exits the engine block. This critical seal prevents engine oil from leaking between the engine and transmission, helping maintain proper lubrication and keeping the clutch, flexplate, and bellhousing area clean. Whether you’re performing a transmission service or rebuilding your engine, replacing the rear main seal helps ensure long-term reliability and prevents costly oil leaks in high-mileage or heavy-duty diesel applications. Manufactured to meet or exceed original equipment specifications, the MAHLE 67777 uses a durable sealing material that withstands high temperatures, crankshaft rotation, and constant engine vibration. Its precision-molded design maintains a tight seal against the crankshaft while minimizing friction and wear. Built for durability and precise fitment.
