Baulk rings are a consumable synchroniser component that controls the speed-matching of gears during gear changes; wear causes notchy, difficult, or crunching gear selection, particularly when the gearbox is cold. Correct replacement with a geometry-matched ring is essential to restore proper synchroniser cone engagement.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eApplies to 3rd, 4th, 5th, and reverse gear synchroniser positions on the R380 mainshaft\u003c\/li\u003e\n\u003cli\u003eFitted to early R380 gearboxes up to gearbox number (G)417153J - verify your gearbox serial number before ordering\u003c\/li\u003e\n\u003cli\u003eSupplied as a single ring; multiple rings are required for a full synchroniser overhaul\u003c\/li\u003e\n\u003cli\u003eWhen replacing baulk rings, inspect synchroniser hub assemblies, selector forks, and cone surfaces for wear simultaneously\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Defender (1986–2006), Discovery 1 (1989–1998), Discovery 2 (1998–2004), and Range Rover Classic models equipped with the R380 gearbox, up to gearbox number (G)417153J where applicable.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
