Cometic Evolution Sportster Pushrod O-Ring Kit 2-Pack - Harley-Davidson Sportster
About Cometic
Cometic Gasket manufactures multi-layer steel head gaskets and complete gasket kits in Concord, Ohio. On a built V-twin running higher compression or a big-bore kit, the MLS head gasket is what keeps the top end sealed — which is why Cometic is the default spec on so many engine builds.
Refresh your Evolution Sportster's top end with this Cometic pushrod O-ring kit. This 2-pack provides all the necessary seals to prevent leaks at the pushrod tubes for both cylinders, ensuring a clean and reliable engine.
