Are you rebuilding or resealing your Duramax engine and need a complete gasket solution? The MAHLE Engine Gasket Set provides the essential gaskets and seals required to properly reseal a GM 6.6L Duramax engine during maintenance, repair, or overhaul. Designed for professional engine service, this kit includes the critical sealing components needed for both upper and lower engine areas, helping restore factory sealing performance and prevent oil, coolant, and combustion leaks. It’s an ideal solution when performing injector work, front cover service, oil pan removal, or general engine resealing without replacing the cylinder head gaskets.

Manufactured to meet or exceed original equipment standards, the MAHLE 95-3726 gasket kit uses OE-grade sealing materials engineered to withstand the high temperatures, pressures, and vibration common in diesel engine applications. The kit typically includes components such as valve cover gaskets, injector seals and O-rings, timing cover gaskets, oil pan gaskets, and various engine sealing components required during service. Each gasket is produced with precision materials and quality control standards trusted by OEM manufacturers and professional technicians, ensuring reliable sealing and long-term durability in demanding operating conditions.
