DNJ® Head Gasket Sets are professional grade sealing solutions engineered for complete top-end engine service or cylinder head replacement. This 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.

DNJ® Cylinder Head Bolt Kits are precision-engineered assemblies designed to secure the cylinder head to the engine block, ensuring a proper seal and maintaining engine performance under extreme thermal and mechanical stress. Each kit includes high-quality head bolts, —or in some applications, studs-and-nuts—along with hardened steel washers, to ensure accurate torque application and consistent clamping force.
DNJ® Cylinder Head Bolt Kits are built from durable, heat-treated carbon or alloy steel. Manufactured to meet or exceed OEM quality standards, these bolts offer excellent strength, fatigue resistance, and stability under high pressure and thermal cycling—critical for maintaining long-term engine performance and gasket sealing integrity. 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.
DNJ® also offers a wide range of related components such as head gaskets, valve train components, and other top-end engine rebuilding products—making it easy to source everything needed for a complete and reliable repair from one trusted supplier. With precision engineering and top-tier materials, DNJ® Cylinder Head Bolt Kits deliver exceptional performance and long-lasting durability.
