Kodlin stretched designer gas tank to fit all HD M8 Softail models from 2018-up. Comes in raw steel, unpainted. It includes a pop-up gas cap and works with the OEM fuel pump. We highly recommend the use of a tank sealer prior to installation. The tank has a capacity of 3.5 gallon (13 liter) and comes with installation instructions. Please note that modifications are necessary when used on Softail models with a dash and a custom seat may be required.
