C9222 EST motor gasket kit. 4-1/8" bore

For a complete engine overhaul on 1999 to 2006 FLT Touring models, this Cometic EST (Extreme Sealing Technology) kit is the professional choice. It includes every gasket, seal, and o-ring needed for the job, including primary gaskets. The kit features .040-inch thick Multi-Layer Steel (MLS) head gaskets that eliminate the need for dowel pin o-rings, and .010-inch Single-Layer Steel (SLS) base gaskets coated in Viton rubber. The rocker cover gaskets are also SLS to prevent weeping or brittleness over time. With 1999–2010 style breather gaskets and high-quality Viton valve seals, this kit ensures a leak-free reassembly.
