Product Details

The Cometic C9111-010 is a high-performance base gasket set designed specifically for Harley-Davidson Twin Cam engines with a 4.250-inch bore. This pair of precision-engineered gaskets features a .010-inch compressed thickness and 4.430-inch inside diameter, providing an optimal seal between the cylinder and crankcase.

Key Features:

  • MLS (Multi-Layer Steel) construction for superior durability and heat resistance
  • 4.250-inch bore diameter for big bore Twin Cam applications
  • .010-inch compressed thickness allows for precise deck height adjustment
  • 4.430-inch inside diameter for proper fitment
  • Sold as a pair (one gasket for each cylinder)
  • Exceeds OEM specifications for sealing performance
  • Ideal for performance builds and engine rebuilds

Cometic gaskets are manufactured using advanced materials and processes to ensure maximum reliability under extreme conditions. The thin .010-inch profile makes this gasket ideal for builders looking to fine-tune compression ratios or deck heights on modified Twin Cam engines. Each gasket is precisely cut to maintain consistent quality and fitment.
