Product Details

The Cometic C9689-044 is a premium Multi-Layer Steel (MLS) head gasket set designed specifically for Harley-Davidson Evolution engines with stock 3.500-inch bore dimensions. This 2-pack includes both gaskets needed for a complete top-end rebuild or engine overhaul.

Key Features:

  • MLS-5 construction with five layers of stainless steel for superior sealing and durability
  • 0.044-inch compressed thickness provides optimal compression ratio for stock applications
  • Precision-engineered for 3.500-inch bore HD Evolution engines
  • Advanced coating system ensures excellent torque retention and resistance to corrosion
  • Eliminates the need for additional sealants or re-torquing after initial installation
  • Conforms to cylinder head and block surface imperfections for reliable combustion sealing

Cometic's MLS gasket technology delivers race-proven performance with multiple layers of stainless steel that move independently to accommodate thermal expansion and engine movement. The proprietary coating provides a micro-seal for superior sealing against combustion gases, coolant, and oil. Ideal for both stock rebuilds and performance applications on Harley-Davidson Evo Big Twin engines.

I sincerly hope the picture is not close to actual part. part number matches what I want , but image is no where close. thanks, steve

Great customer service!!! fantastic pricing!!! quick delivery!!! Highly recommended thmotorsports.com!!!

Easy check out. Literally the best check out payment experience I've ever experienced.

I received the part number from bayliner to order but it is 2 feet too long , how do I exchange it

I was not informed that my order was shipped out. When I called and asked about it the rep said it would ship out next week. Later that day I got a notice from FedEx that my order was out for delivery. The product I bought was the correct item I ordered ' brand new in the box' so everything was good in that way.
