MAHLE Original American Motors Ambassador 71-65 Rear Main Seal Set

This is the Victor Reinz JV1611 rear main seal set, a crucial part for sealing the crankshaft where it exits the engine block. It's designed to fit a broad spectrum of vehicles, including many American Motors models like the Ambassador and Concord, as well as a variety of Jeep vehicles such as the CJ5 and Cherokee. A properly functioning rear main seal prevents oil from leaking out of the engine, which is essential for maintaining oil pressure and preventing damage.

This seal set is well-built to handle the pressures and temperatures found in the engine's lower end. It's a direct replacement for the original seal, meaning it should fit right into place during an engine rebuild or when addressing an oil leak from the rear of the crankshaft. Replacing this seal is often done when the transmission is removed, making it a good time to ensure you're using a reliable part to avoid having to do the job again soon.
