DNJ® Head Gasket Sets are professional grade sealing solutions engineered for complete top-end engine service or cylinder head replacement. This comprehensive set ensures critical sealing between the cylinder head and engine block, maintaining combustion pressure and preventing oil, coolant, and gas leaks. Each set includes all necessary components for reassembly, such as head gaskets, upper and lower intake manifold gaskets, plenum gaskets, exhaust manifold gaskets, valve cover gaskets & grommets, valve stem seals, camshaft seals, spark plug tube seals (when applicable), thermostat gaskets, and a wide assortment of O-rings and seals. DNJ® Head Gasket Sets are manufactured using non-asbestos materials and are designed to meet or exceed OEM quality standards. A variety of materials used in the set include Multi-Layer Steel (MLS) for head gaskets—ideal for modern engines operating under high pressure—Graphite and non-asbestos composite materials for specific applications, and rubber, silicone, and EPDM for coolant, oil, and valve cover sealing. Premium Viton® valve stem seals provide excellent resistance to heat and oil. DNJ® proudly offers the largest inventory of MLS head gasket sets in the industry, ensuring coverage for a wide range of domestic and import vehicles. DNJ® also offers a complete line of Head Bolts, which is critical for proper cylinder head installation. It is important to note that Torque-To-Yield (TTY) head bolts must never be reused, as reinstallation can compromise clamping force and lead to engine failure. With precision engineering and top-tier materials, DNJ® Head Gasket Sets deliver exceptional performance and long-lasting durability.
