WG2210100199 Range Gear Synchronizer Ring is a core part of the auxiliary gearbox for Sinotruk Howo HW series gearboxes, suitable for heavy-duty models such as 70-ton wide-body mining trucks.

Made of high-copper alloy material, it features a stable friction coefficient, excellent wear resistance and heat resistance, effectively avoiding high-temperature ablation and abrasion.

The precisely ground tooth surface ensures smooth meshing, shortens synchronization time, enables easy gear shifting without abnormal noise, and reduces the risk of gear knocking.

Manufactured in accordance with original factory standards, it has precise dimensions and good interchangeability. It adapts to harsh mining and working conditions, greatly lowers the gearbox maintenance rate, and delivers durable and reliable performance.
