Product Details

The Cometic C9217 is a comprehensive top end rebuild kit engineered for Harley-Davidson Twin Cam engines with 1550cc big bore configurations. This kit features Cometic's advanced EST (Extreme Sealing Technology) design, incorporating embossed stainless steel head, base, and rocker gaskets covered with a proprietary rubber material for superior sealing performance.

Key Features:

  • Complete top end rebuild kit includes all gaskets, seals, O-rings, and washers from cylinder base up to rocker boxes
  • EST technology allows heat to be drawn away from the combustion ring and dissipated evenly across the gasket surface to eliminate hot spots and gasket failure
  • Designed for .530" O.D. valve guides commonly found in big bore and performance applications
  • MLS (Multi-Layer Steel) head gaskets provide exceptional durability under high cylinder pressures and temperatures
  • Viton-coated base gaskets and blue Viton valve stem seals for extended service life
  • Made in the USA with materials manufactured on American soil

Cometic gaskets are engineered to meet the demands of modern high-performance engines producing increased horsepower, higher cylinder pressures, and extreme temperatures. This complete kit provides everything needed for a professional quality top end rebuild on your big bore Twin Cam engine.

All good.

1st time customer, glad to find this item on sale for my Jeep! Looking forward to more great deals in the future!

Great

everything is as expected. Cant wait to get my wires.

It was great! I found what I was looking for on your website and it was the best price anywhere online so I purchased it. I received it within a few days

I saw in a big box store something I wanted but got sticker shock with the price. Boatplicity had the extract same thing for 20% less. It was delivered to my home in a very speedy manner and was very well packed so it was in pristine condition. I will use this site again!
