Product Info

• Part Number: WG2210100009

• Product Name: Synchronizer Ring

• Applicable Vehicle: SINOTRUK HOWO, Steyr, HOHAN heavy trucks

• Matching Gearbox: HW series 10/12 speed auxiliary transmission

• Function: This synchronizer ring fits between shift sleeve and cone hub. Its inner tapered friction surface generates friction to balance rotational speed of gears when switching high and low ranges. It eliminates rigid collision between meshing teeth, realizes smooth gear shifting and protects the whole gearbox set under full-load transportation, mountain climbing and long-distance driving.

Production Craft

• High-quality bronze alloy raw material with good friction coefficient and anti-abrasion property

• Precision CNC machining for inner taper surface to guarantee tight fit with cone hub

• Strict surface treatment to avoid cracking and deformation under frequent friction

• 100% dimensional inspection before delivery to meet OEM standard

Key Features

✅️Exact OEM Standard OE No. WG2210100009

Fully consistent with original size and taper, direct installation without modification, perfectly matched SINOTRUK HW series gearbox.

✅️Premium Wear-Resistant Bronze Alloy Material

High copper content material maintains stable friction, not easy to burn or wear thin under frequent high-low gear switching, greatly extend service cycle.

✅️Smooth Shifting, Eliminate Gear Clashing Noise

Uniform taper surface provides stable friction synchronization, solves common faults like hard shifting, gear knocking and abnormal transmission noise caused by old damaged sync rings.

✅️Strong Pressure & High Torque Resistance

Withstand frequent shifting impact of fully loaded tractors and dump trucks, stable performance under harsh working conditions such as mountain roads and long haul.

✅️Rigorous Multi-Round Quality Testing

Each piece passes dimension check, friction test and surface flaw screening, no burr, deformation or unqualified taper. Stable quality for bulk export orders.

✅️Cost-Effective Aftermarket Replacement Parts

Factory direct supply, competitive price compared with genuine parts, same using performance, ideal choice for truck repair shops and spare parts distributors.

✅️Wide Compatibility for SINOTRUK Heavy Trucks

Compatible with HOWO 336, 371, 420HP cargo trucks, tractors and dump trucks equipped with HW10/12-speed auxiliary gearbox.
