Let Aeroflow Performance supply the very best in engine gaskets for your engine rebuild. These oil pan gasket kits are available in a cork or rubber material designed for an OE factory replacement engine. For high performance engines we recommend the silicone with steel core. Cork and rubber gaskets are recommended for street engines, where they are not requiring to come off multiple times. They're made from high-density cork and/or rubber gasket material. This construction means that they are non-shrink and non-stick, don't have to be re-torqued, and can be reused. For race engines the silicone moulded rubber with steel core construction and steel compression limiters are the go-to. They can be reused multiple times and do not require any extra sealant. These gaskets feature superior-quality rubber and steel, which outlast cork and rubber designs to provide years of dependable service.
