Baulk rings control the speed-matching process between gear and shaft during gear selection; worn rings cause slow, notchy, or crunching gear changes - most commonly reported on 3rd and reverse in high-mileage R380 units. Correct replacement restores synchroniser function and prevents accelerated wear to adjacent synchro components.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eFits the R380 gearbox mainshaft synchroniser stack for 3rd, 4th, 5th, and reverse gear positions\u003c\/li\u003e\n\u003cli\u003eApplies to early R380 units up to gearbox serial number (G)417153J\u003c\/li\u003e\n\u003cli\u003eSupplied to OEM specification as a direct replacement for Land Rover part FTC5018\u003c\/li\u003e\n\u003cli\u003eMultiple rings are typically required per rebuild - inspect all synchroniser rings together and replace as a set where wear is present\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, all equipped with the R380 manual gearbox up to serial number (G)417153J.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
