Part #: SB1001 - 039. JE Pro Seal Head gaskets are top - notch! They're made from high - grade AISI 304 Stainless Steel. We use advanced techniques like in - line laser cutting and multi - stage embossing to guarantee top - level quality. Each layer of our Multi - Layered Steel gaskets is precisely cut and formed for peak performance. Our proprietary coating technologies create an amazing seal between the head and block. They usually eliminate the need for extra deck surfacing. The coating fully covers all exposed metal, much better than other products with exposed raw steel edges. The layers have fluoroelastomer (FKM) for great temperature and chemical resistance. This tech offers excellent conformability, oxidation resistance, and easy removal even after high - temp exposure. *Sold Individually. Specs: Gasket Bore - 3.937 inches (100.00 mm), Thickness - 0.039 inches (1.00 mm).
Using your JE Pro Seal headgasket is straightforward. First, make sure the mating surfaces of the head and block are clean and free of debris. Carefully place the headgasket in position. You usually won't need additional deck surfacing because of the special coating. When installing, be gentle to avoid damaging the gasket. For maintenance, keep it in a dry place away from extreme temperatures. If you notice any signs of wear or damage, replace the gasket right away. Also, follow your vehicle's manual for the correct torque sequence when tightening the head bolts.
