SINOTRUK HOWO Truck Transmission System Parts HW19710 Range Synchronizer Ring WG2210100009

The WG2210100009 Range Synchronizer Ring delivers precise, dependable performance in the range gear section of SINOTRUK HOWO heavy-duty truck transmissions, playing a critical role in the synchronizing mechanism during range selection. Engineered for the demanding conditions of commercial vehicle operation, the ring works through controlled frictional engagement with the corresponding synchronizer components to rapidly equalize rotational speeds before the selected range is fully engaged, minimizing impact and shock between mating parts during gear changes. This performance characteristic directly contributes to smoother, more reliable range shifting, reduced wear on synchronizer hubs, sleeves and shift forks, and extended service life for the overall gearbox assembly — an essential advantage for heavy-duty vehicles operating under frequent load changes, long-haul highway transport, construction duties and other high-stress drivetrain conditions. SINOTRUK transmission documentation identifies WG2210100009 as a range synchronous ring and specifies two pieces within the corresponding range gear assembly, with application references covering HW19710, HW18709 and HW20716 transmissions, confirming its proven integration across multiple heavy-duty gearbox platforms. Built to maintain consistent frictional performance and dimensional stability throughout its working life, the component is an ideal choice for transmission overhaul, range gear repair, synchronizer replacement and heavy-duty fleet maintenance. For accurate replacement, buyers should verify the complete OEM number WG2210100009, transmission model, range gearbox configuration, synchronizer sleeve, synchronizer hub, and original ring dimensions, as similar synchronizer rings may differ in friction surface, dimensions, and transmission application.
