• Complete Engine Overhaul Solution – This comprehensive gasket kit includes every seal and gasket needed for a complete engine rebuild. From the cylinder head to the oil pan, all mating surfaces are covered, eliminating the need to source individual components separately.
• OEM-Spec Cylinder Head Gasket – The cylinder head gasket is manufactured to original equipment specifications, ensuring proper combustion sealing and compression. Available in MLS (Multi-Layer Steel) or high-grade graphite composite depending on engine application, providing excellent heat resistance and long-term durability under extreme operating conditions.
• Precision-Fit Oil Pan Gasket – Includes the oil pan gasket (OEM 5281440) designed specifically for the QSF2.8's oil pan configuration. Ensures a leak-free seal between the oil pan and engine block, preventing oil leaks that can lead to engine damage.
• High-Temperature Seal Materials – All seals exposed to high heat, such as turbocharger and exhaust manifold gaskets, are manufactured from high-temperature materials including Viton and multi-layer steel. These materials withstand the extreme temperatures generated by modern Tier 4 diesel engines.
