Part #: SB1001-051. Our JE Pro Seal Head Gaskets are crafted from top - notch AISI 304 Stainless Steel, the finest raw material available. We use advanced techniques like in - line laser cutting and multi - stage embossing to guarantee the highest quality. Each layer of our Multi - Layered Steel gaskets is precisely cut and shaped to boost performance. Our proprietary coating technologies are a game - changer. Multiple layers create an ultimate seal between the head and block mating surfaces, often eliminating the need for extra deck surfacing. Our coating fully encapsulates all exposed metal, far better than products with exposed raw steel edges. The layers feature fluoroelastomer (FKM) for excellent temperature and chemical resistance, offering great conformability, oxidation resistance, and easy removal even after high - temperature exposure. Specs: Gasket Bore - 3.937 inches (100.00 mm), Thickness - 0.051 inches (1.30 mm).


Using this JE Pro Seal head gasket is straightforward. First, make sure the head and block mating surfaces are clean and free of any debris. Place the gasket carefully between the head and the block, aligning it properly. Then, follow the manufacturer's torque specifications when tightening the bolts. As for maintenance, it's a good idea to check the gasket regularly for any signs of wear or damage. If you notice any leaks or other issues, it might be time to replace the gasket. When installing or removing the gasket, be gentle to avoid damaging the layers. This will ensure the long - lasting performance of your engine.
