Set of gaskets for the upper part including the correct main gasket, cylinder head gasket, and cylindrical O-rings, as well as other special O-rings or seals required for replacing the upper part. MLS cylinder head gaskets provide even distribution of torque on the sealing surface of the gasket, ensuring less deformation of the hole and better sealing of the piston ring for higher performance. 4-stroke head gaskets are designed for use in higher-performance 4-stroke atmospheric and turbo engines, with a multilayer steel design and coated with Viton elastomer coating. The EST (Extreme Sealing Technology) gasket set includes head, base, and rocker gaskets made from stainless steel, coated with a patented rubber material. The head gasket material allows heat to be dissipated from the combustion ring and evenly dispersed across the gasket surface, minimizing hot spots and damage to the gasket. Manufactured in the USA.
