About This Product
When servicing the exhaust on the latest generation of liquid-cooled Harleys, a fresh seal is mandatory. This MCS cylinder head to exhaust header gasket is designed for the oval exhaust ports found on 2020 to 2026 Pan America, 2021 to 2026 Sportster S (RH1250S), and 2022 to 2026 Nightster models. These bikes typically require two gaskets for a full service. As a high-quality replacement for OEM reference 65900051, this gasket ensures a leak-free connection between the head and the header pipe, preventing power-robbing exhaust leaks and popping. Identified by part 938859, it is a precision-engineered component built to withstand the high temperatures of the Revolution Max engine.
Manufacturer part number: 938859.
