Set of gaskets for the top end, which includes main head gaskets and cylindrical O-rings, as well as other special O-rings or seals required for top end repair. MLS head gaskets provide uniform torque distribution on the sealing surface, reducing cylinder distortion and ensuring better sealing of the piston ring for more power. Head gaskets for 4-stroke engines are designed to operate on high-performance 4-stroke atmospheric and turbocharged engines, using multilayer steel construction with outer layers and a Viton rubber coating. The EST (Extreme Sealing Technology) gasket set includes embossed stainless steel head, base, and rocker gaskets, covered with proprietary rubber material. The head gasket material allows heat to be removed from the combustion ring and evenly distributed across the gasket surface, eliminating hot spots and gasket damage. Made in the USA.
