Set of gaskets for the top part of the motorcycle, including the proper base, cylinder head gasket, and cylindrical O-rings, as well as other special O-rings or seals necessary for R&R of the top end. MLS cylinder head gaskets promote even distribution of torque on the sealing surface, ensuring less deformation of the hole and better sealing of the piston ring for increased power. Head gaskets for four-stroke engines are designed to operate in today's most powerful four-stroke atmospheric and turbo engines, using multi-layer steel construction with outer layers that are textured and coated with Viton rubber coating. These head gaskets are designed to meet the demands of today's high-performance and high-pressure cylinder engines. The EST (Extreme Sealing Technology) gasket set includes textured stainless steel gaskets for the head, base, and rocker, coated with proprietary rubber material. The 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.
