Product Details

The Cometic C9689-030 is a high-performance Multi-Layer Steel (MLS) head gasket set designed for Harley-Davidson Evolution engines with stock 3.500" bore. This 2-pack features premium stainless steel construction with a .030" compressed thickness, providing superior sealing and durability for high-compression and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for maximum strength and reliability
  • Stock bore size of 3.500" for HD Evolution engines
  • .030" compressed gasket thickness
  • Stainless steel material resists corrosion and withstands extreme temperatures
  • Includes 2 head gaskets per package
  • Superior torque retention and reusability compared to composite gaskets
  • Precise embossments ensure optimal sealing at combustion chamber and coolant passages

Cometic MLS head gaskets are engineered to handle the demands of high-performance builds, providing exceptional sealing even under extreme cylinder pressures. The multi-layer stainless steel design allows for minor surface imperfections while maintaining a reliable seal, making these gaskets ideal for both stock rebuilds and modified applications.

I found good quality product more cheaper here. I installed the shocks. Did not have any problem.

We shall see

I’ve bought here a few times with great success

Best price. Quick delivery. All done from the comfort of home. Doesn't get any better than that!

Delivery was on time as advertised and part was just as advertised. Great service.

Best price I could find and free shipping.

Free shipping and the lowest price I found online for a quality tractor tire. I was shocked to received the tire so fast- in two days. At first, I was hesitant to order because I had never heard of boatplicity, but now I will order again when I need the other tractor tire.
