The Cometic EST Gasket Kit is a complete set of gaskets, seals, washers, and o-rings for a full engine overhaul. Rather than sourcing each component separately, you get everything needed in one package for a rebuild of the engine.
The kit includes Multi-Layer Steel (MLS) head gaskets for sealing, steel Viton-coated base gaskets for durability, and blue Viton valve stem seals for reliable valve train sealing. The components are made from AFM material, which is described as providing reliable, long-lasting seals.
Because every mating surface is supplied with its own seal, the kit is designed to help maintain sealing, oil retention and overall engine condition through the overhaul. It is a practical choice for riders who want a single, complete gasket set from Cometic.
Cometic part number C9917. Weight is 0.86 lbs.

Gasket
Working fine was for my brother's bike
Works Fine at a lower cost
I usually have an OEM from Harley Davidson, I have used this twice on my 04 Electraglide, no leaks or issues. At a much lower price.
A mediocre gasket
I didn’t use this gasket after removing the derby and seeing the Harley gasket that I removed. No comparison in quality. I ended up going to the local dealer and bought an O.E. gasket.
A good buy
The gasket fit nicely and no leaks so far . The fitment was spot on .
There is nothing on them indicating they are actually Cometic gaskets. Are they Substitutes?
