About This Product
When you're building a big-bore Milwaukee-Eight, sealing the top end is critical. This Cometic kit is designed specifically for custom 4.125-inch bore engines, featuring .030-inch Multi-Layer Steel (MLS) head gaskets and .020-inch Rubber Coated Metal (RCS) base gaskets. The gasket bore diameter measures 4.205 inches, providing the necessary clearance for high-performance setups. This kit includes everything needed to service one engine and is sold as a pair. It fits 2018 to 2025 Softail models, as well as 2017 to 2025 Touring and Trike models equipped with custom 4-1/8 inch bore cylinders. Cometic is the industry standard for a reason, offering superior recovery and sealing properties for high-compression builds.
Manufacturer part number: C10167-HB-030.
