Cometic C9970-CR EST Top End Gasket Kit for Harley-Davidson Sportster - 1200 2004-2006

The Cometic C9970-CR EST Top End Gasket Kit provides a complete sealing solution for Harley-Davidson Sportster 1200 Evolution engines from 2004-2006. EST stands for 'Extreme Sealing Technology', representing Cometic's most advanced gasket materials engineered for superior durability and leak-free performance.

Advanced MLS Head Gasket Technology:

This kit features a .040" MLS (Multi-Layer Steel) cylinder head gasket with a 3.500" bore. The gaskets are made from embossed stainless steel, coated with a high temperature viton material that virtually eliminates leakage. The head gasket material allows heat to be drawn away from the combustion ring and dissipated evenly across the gasket surface to eliminate hot spots and gasket failure.

Complete Top End Rebuild Kit:

This EST Top End gasket kit includes every gasket, seal, washer, and O-Ring from the base gasket up to the rocker boxes needed for a top end rebuild. EST gaskets are used in critical sealing surfaces such as rocker box and cylinder base gaskets, with reinforced gasket material compounds like armor-clad, graphite and galvanized steel constructed for sealing irregular surfaces.

• 2004-2006 Harley-Davidson XL1200R Sportster 1200 Roadster
