Cometic Hi-Performance Top End Gasket Kit for 4-Stroke

Ensure peak performance and unmatched reliability for your 4-stroke engine with the Cometic Hi-Performance Top End Gasket Kit. Engineered with advanced sealing technologies, this comprehensive kit provides everything needed for a complete top-end rebuild, guaranteeing a perfect seal and optimal power delivery for your motorcycle.

Description

The Cometic 4-Stroke Top End Gasket Kit is meticulously designed for today's most demanding high-output, naturally aspirated, and boosted 4-stroke machines. This kit includes all essential gaskets and O-rings for your top-end rebuild, such as base, head gasket, and cylinder O-rings, ensuring a precise fit for a 94.00 mm (3.700") bore. At its core are the Multi-Layer Steel (MLS) head gaskets, renowned for promoting an even torque load across the sealing surface. This innovative design significantly reduces bore distortion, leading to a superior piston ring seal and ultimately, more power and efficiency from your engine. The MLS gaskets feature embossed outer layers coated with a durable Viton rubber, specifically engineered to withstand the extreme pressures and temperatures of high-horsepower applications.

Further enhancing its capabilities, the kit incorporates Cometic's Extreme Sealing Technology (EST), utilizing embossed stainless steel head, base, and rocker gaskets covered with a proprietary rubber material. This advanced gasket material is crucial for drawing heat away from the combustion ring, dissipating it evenly across the gasket surface. This critical function eliminates localized hot spots, preventing premature gasket failure and extending engine life. With a precise thickness of 0.46 mm (0.018"), this Cometic Hi-Performance gasket kit delivers the robust sealing and durability required for sustained, aggressive riding, all proudly Made in the USA.
