Cometic MLS Head Gaskets 3.50" .030" MLS #C9688 Harley Davidson Sportster

Product Details

Provides maximum sealing performance for today's high output engines and require no sealants. Ideal for aluminum heads to aluminum blocks and aluminum heads to cast iron blocks, withstanding the shearing force created by the two materials.

No need to re-torque, the embossing design of the MLS gasket promotes an even clamp load across the sealing surface allowing for measurable reduced bore distortion.

Cometic MLS Gaskets are comprised of multiple layers of stainless steel, due to its increased strength, ability to rebound and resistance to corrosion.

The outer layers of the gaskets are embossed and coated on both sides with rubber; a flouro-elastomer rubber based material that is heat resistant to 250 Celsius /482 Fahrenheit. Rubber is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes.

The center or shim layer is uncoated stainless steel layer which can be varied to accommodate multiple thickness requirements.

  • Made in the USA

NOTE: Replaces OEM #16770-84B. For stock bore only.
