SPI CRANKSHAFT OIL SEAL SET

Our gaskets are manufactured to OE specs, which means no trimming or fitment issues. Our materials are explicitly selected for their temperature, oil, fuel, and coolant-resistant qualities as well as tested using ASTM standards. Each design is evaluated against rigid quality-control standards to ensure each set meets or exceeds OE performance. In some cases different base gaskets may be used depending on the cylinder production. In our kits, all base gasket size options are included in both top & full sets.
