SBC Rear Main Seal - 2-Piece

The SBC Rear Main Seal - 2-Piece from SCE GASKETS is a reliable sealing solution designed for small-block Chevrolet engines. It is ideal for those undergoing rebuilds, restorations, or high-performance modifications. This two-piece design effectively addresses the critical junction where the crankshaft exits the block, a common leak point in vintage and modified SBC platforms.

The two-piece construction simplifies installation compared to one-piece designs, minimizing the risk of crankshaft scoring during assembly. This rear main seal is crafted from molded elastomer material, which is designed to maintain its sealing geometry across various temperature ranges, ensuring effective sealing over time.

Engine builders and mechanics working on small-block Chevrolet applications, from stock 283ci engines to modified versions, can rely on this seal for complete bottom-end overhauls and crate engine installations. It is compatible with any SBC platform where the factory rear main bore remains standard.
