When servicing the primary on a modern 6-speed Twin Cam, you need seals that can handle the job. This James Gaskets kit is designed for 2006–2017 Dyna, 2007–2017 Softail, 2007–2016 Touring, and 2009–2016 Trike models. It provides a comprehensive solution for sealing the primary drive, replacing OEM part 31433-84A. While the fitment covers a wide range of Big Twins, it also finds applications across various FXR and Sportster configurations requiring this specific seal profile. These gaskets are manufactured to exacting standards to prevent leaks and ensure the primary chain and clutch assembly remain properly lubricated. Whether you're doing a simple fluid change or a deeper inspection, using high-quality James Gaskets components ensures your 6-speed drivetrain stays bone dry on the outside.
