Land Rover Part Number: STC3377 - Synchroniser Kit Mainshaft 5th & Reverse
STC3377 is a synchroniser kit for the mainshaft 5th and reverse gears fitted to the R380 5-speed manual gearbox. It replaces the synchroniser assembly components used for 5th gear and reverse and is intended where synchroniser rings, hubs or related components require renewal as part of a gearbox rebuild or repair. The synchroniser assembly matches the rotational speeds of the mainshaft and the selected gear during a shift, permitting smooth engagement without gear clash; worn synchronisers commonly produce grinding, missed selection or increased shift effort for the affected gears.
