Description
A leaking rear main seal is one of the most common sources of oil seepage on classic Small Block Chevy engines, and ignoring it only accelerates damage to your crankshaft and clutch assembly. Fel-Pro’s two-piece rubber rear main seal is engineered to restore a reliable, lasting seal without requiring complete engine disassembly—making it the smart choice for rebuilds, restorations, and preventive maintenance. Trust the seal that’s been the industry standard for decades.
