Show original supplier description
The BMW synchronizer ring (part number 23231224325) is a genuine component designed for your vehicle's manual transmission. This precision-machined part, typically made of brass or steel, plays a critical role in enabling smooth, grind-free gear changes. It functions by synchronizing the speed of the gear you intend to engage with the speed of the transmission shaft, utilizing friction surfaces before the dog teeth engage. Symptoms of a worn synchronizer ring can include gear grinding during shifts (especially between 2nd and 3rd gears), difficulty engaging gears that requires excessive force, or gear pop-out under load due to the synchro's inability to securely hold the gear. This Genuine BMW part is designed for specific models, including the 525i, 535i, 535is, 635CSi, 735i, L6, and L7, typically from model years 1985 through 1993. It is important to verify fitment for your exact vehicle configuration.
