The BBC 2pc. Rear Main Seals - 10-Pack (model 1305-10) is an essential maintenance solution for big-block Chevrolet engine builders and enthusiasts engaged in crankshaft work. This product is particularly useful for those performing complete engine rebuilds, upgrading performance rotating assemblies, or addressing oil leaks at the rear main bearing. The bulk 10-pack ensures that users have multiple quality seals readily available, reducing the need for repeat orders.

Engineered as a two-piece design, these rear main seals are crafted to provide a precision fit and maintain material integrity, effectively containing crankcase pressure and preventing oil leaks. The two-piece configuration offers superior sealing performance compared to single-piece designs, allowing for proper compression and alignment during installation.
