Engineered for demanding 4-stroke engines, this comprehensive kit provides all the essential gaskets and seals required for a complete top end rebuild, guaranteeing a precise fit and superior sealing.

Description

The Cometic Hi-Performance Top End Gasket Kit is meticulously designed to meet the rigorous demands of today's highest-output 4-stroke naturally aspirated and boosted machines. This comprehensive kit includes the correct base, head gasket, cylinder O-rings, and other top end specific O-rings or seals necessary for the removal and reinstallation (R&R) of your engine's top end. At its core is the advanced Multi-Layer Steel (MLS) head gasket, a hallmark of Cometic's commitment to quality. This MLS design promotes an even torque load across the sealing surface, significantly reducing bore distortion and enhancing piston ring seal for measurable power gains. Crafted with outer layers embossed and coated with a durable Viton rubber, these head gaskets are built to withstand high cylinder pressures and extreme temperatures. With a precise 97.00 mm (3.818") bore size and a thickness of 0.71 mm (0.028"), this Cometic gasket kit ensures optimal compression and heat management, preventing hot spots and premature gasket failure. Made in the USA, it delivers the extreme sealing technology (EST) you can trust for your motorcycle's engine rebuild.
