• Premium MLS Head Gasket - The core cylinder head gaskets adopt multi-layer steel (MLS) structure with high-temperature resistant sealing coating. This design provides excellent compression resistance and thermal stability, effectively withstanding high combustion pressure and extreme temperature changes inside the engine. The precision-manufactured steel layers maintain stable sealing performance even under long-term heavy load operation, reducing the risk of blown head gasket failure.
• Complete Overhaul Seal Kit - The kit includes all necessary sealing components required for a full cylinder head overhaul job: 2 pieces of cylinder head gaskets, valve cover gaskets, intake manifold gaskets, exhaust manifold gaskets, timing cover gasket, valve stem seals, O-rings, seal washers and other auxiliary sealing parts. You do not need to purchase additional sealing accessories separately, enabling one-stop procurement for the entire engine head repair project and saving purchase time and cost.
• Reliable All-Round Sealing - All gaskets and seals are manufactured with engine-grade materials to match original factory sealing specifications. The rubber components feature excellent oil resistance and heat aging resistance, while composite gaskets provide reliable sealing for coolant and oil passages. The complete set effectively resolves common engine failures caused by worn gaskets, including coolant leakage, oil seepage, engine overheating, white exhaust smoke, compression loss and reduced engine power.
• Precision Fit for Repair - All bolt holes, fluid passages and cylinder openings are precisely machined to match the original engine dimensions, ensuring perfect alignment with the cylinder block and head. The gaskets are engineered to accommodate minor surface imperfections on aged engine blocks and heads, making them suitable for daily repair and rebuild scenarios.
