JIMS Rebuild Kit (manufacturer part no. 1068) — Complete set for overhauling a 6-speed gearbox, made in the United States. Designed to replace essential wear components (seals, rings, locks, and bearings), this kit allows for a complete revision of the transmission to restore sealing and controlled internal play during refurbishment.
This kit is aimed at mechanics and riders undertaking a serious restoration or overhaul of the gearbox. Replacing worn sealing and guiding parts limits oil leaks, reduces lateral play, and contributes to sharper gear engagement. Professional installation is recommended to ensure the fitting and alignment of the components.
Common compatibilities: suitable for the following Harley-Davidson models (examples): FLSTFBS Fat Boy S (2017), FLSS Softail Slim S (2017), FXSB Breakout (2017). Check the original reference before ordering to confirm compatibility.
