About This Product
This MCS cylinder head holder is a workshop essential for anyone tearing down modern Harley engines. It features M10x1.0 and M12x1.25 threaded ends designed to screw directly into the spark plug hole, providing a rock-solid mounting point. Once the tool is clamped into your workbench vice, you have perfect, stable access to the head for porting, valve work, or cleaning without the component sliding or moving. It fits a wide range of models including 2017 to 2026 Milwaukee-Eight, 1999 to 2017 Twin Cam, and 1986 to 2022 Sportster XL models. It also covers 2008 to 2012 XR1200, 2021 to 2026 Revolution Max models like the Pan America and Sportster S, plus 1987 to 2010 Buell XB and 2015 to 2020 Street XG models.
