The gasket set for the top part includes the proper main gasket and cylindrical O-rings, as well as other special O-rings or seals necessary for replacing the top part. MLS main gaskets provide even torque distribution across the gasket surface, ensuring less cylinder deformation and better sealing of the piston ring for increased power. 4-stroke main gaskets are designed to operate in 4-stroke atmospheric and supercharged engines, using a multilayer steel design with outer layers that are embossed and coated with Viton rubber. These main gaskets are engineered to meet the demands of today's high-power and high-pressure engine cylinders. The EST (Extreme Sealing Technology) gasket set includes embossed main, base, and rocker gaskets made from stainless steel, coated with patented rubber material. The gasket material allows heat dissipation from the combustion ring and even distribution across the gasket surface, eliminating hot spots and preventing gasket damage.
