MAHLE Original Buick Apollo 75 Rear Main Seal Set

If you're rebuilding the bottom end of your engine, especially if you're dealing with a classic or a wide range of American vehicles, a new rear main seal is a must-have. This seal sits at the back of the crankshaft, where it meets the flywheel, and its job is to keep oil from leaking out of the engine. A worn-out seal can lead to significant oil loss, which is bad news for your engine's health.

This rear main seal set from Victor Reinz is a well-built replacement designed to fit a variety of vehicles, from the 1975 Buick Apollo to many Buick, Cadillac, and Chevrolet models, as well as a broad selection of Ford trucks and cars from the 1950s and 60s. Victor Reinz is a well-known name in engine sealing, and this set is made to meet the original specifications to ensure a proper seal and help prevent leaks. It's a straightforward part to replace when the engine is already apart for other work, like a clutch job or a full rebuild.
