The MAHLE 48384 Rear Main Engine Crankshaft Seal is designed to restore a proper seal at the rear of the crankshaft, helping keep engine oil contained while maintaining consistent lubrication throughout the engine. Built as an OE-quality replacement for 5.9L and 6.7L Cummins engines, it provides dependable sealing performance for engine repairs, preventative maintenance, or complete rebuilds. Designed to match factory specifications, it delivers a secure fit that helps keep your engine running clean and efficiently.
Manufactured with durable, oil-resistant materials and precision-engineered sealing surfaces, the MAHLE 48384 is built to handle the high heat, pressure, and vibration common in diesel applications. The sealing lip maintains consistent contact with the crankshaft surface to prevent leaks while still allowing smooth crankshaft rotation. Built to meet or exceed original equipment standards, this rear main seal installs as a direct replacement and provides the long-term reliability needed for demanding diesel engines. Maintaining a proper seal at the crankshaft helps protect internal components and ensures your engine retains the lubrication it needs for long service life.
