About this part

Product Details

When you're rebuilding the top end of your Twin Cam engine, getting the seals right is critical. These O-rings from Cometic are designed to seal the cylinder head and base dowel locations, preventing leaks and ensuring proper engine function. They are a direct replacement for the original equipment, fitting a wide range of Harley-Davidson models from the late 90s through 2017, including popular bikes like the Road King, Electra Glide, and Fat Boy.

This pack comes with ten O-rings, giving you enough for a complete job and a few spares just in case. They are made from a durable rubber compound that holds up to engine heat and oil, maintaining a tight seal over time. Proper installation of these O-rings is key to preventing oil or combustion leaks between the cylinder head and the crankcase or cylinder base.
