Description
A failing rear main seal is one of the most common causes of oil leakage in classic Small Block Ford engines—and it's a leak that only gets worse with time. This OEM-spec replacement seal restores the critical barrier between your crankshaft and engine block, preventing oil loss that can compromise lubrication and damage your engine's longevity. Whether you're rebuilding a 351 or addressing a chronic drip, this single-piece seal delivers the reliability you need.
