Product Details

The Cometic C9747-030 Top End Gasket Kit is engineered for Harley-Davidson Evolution Big Twin engines (1984-1991) requiring .030" oversize head gaskets. This complete EST (Extreme Sealing Technology) kit provides all necessary gaskets, seals, and O-rings to rebuild the top end from the cylinder base upward.

Key Features:

  • Multi-Layer Steel (MLS) head gaskets with .030" thickness for precise compression control
  • Embossed stainless steel construction with proprietary rubber coating dissipates heat evenly to eliminate hot spots
  • Includes head gaskets, base gaskets, rocker box gaskets, intake seals, and exhaust gaskets
  • Blue Viton valve stem seals and pushrod tube seals included
  • 3.500" bore size compatibility
  • Made in USA with American-manufactured materials

The advanced MLS construction allows heat to be drawn away from the combustion ring and distributed across the gasket surface, preventing gasket failure under high cylinder pressures and extreme temperatures. Replaces OEM part number 17033-83-A.

I got an exact replacement for the anchor pulley I broke so I could use the same mounting holes on my boat.

Very nice web site.

easy!

First order experience was great. Received the day after I ordered. I ordered the very same item on Jul 21st, got a shipping notification and tracking number but the item appears to be stalled somewhere. I need it sooner rather than later. I have spoken with customer service via telephone call and online chat, but not getting much of a response from either. Appreciate someone looking into it as I need this item quickly. Thanks, Tim.

Very good
