COMPLETE GASKET KIT - Part Number 77-417
Cometic gasket introduces EST (Extreme Sealing Technology) hi-performance gaskets for H-D Evolution and Twin Cam motors. EST is the ultimate in gasket sealing technology. EST's embossed stainless steel metal substrate is coated with a proprietary hi-temperature rubber material that virtually eliminates leakage when joining two metal surfaces. EST gaskets eliminate the use of dowel-pin O-rings. EST base gaskets, which are .020" thick and have .005" of high temperature rubber on both sides, are the strongest on the market. EST rocker box gaskets are .020" thick and have .005" of high temperature rubber on both sides and will not weep, extrude, tear or become brittle over time. The balance of kit components are of the same high quality that you have depended on and include hi-performance exhaust gaskets which do not hinder exhaust gas flow and will not fray into the exhaust port and valve seals utilizing viton rubber and outer springs for a tight seal.
