China Heavy Duty Truck Sinotruk HOWO Truck Body Spare Parts Front Suspension Transition Bracket AZ1664430042

The Cab Left Front Suspension Transition Bracket (Part No. AZ1664430042 / WG1664430042) is a critical structural component in the cab suspension system of Sinotruk (China National Heavy Duty Truck Group Co., Ltd.) heavy-duty trucks. Officially named the Cab Left Front Suspension Mounting Adapter, it serves as the essential interface between the front cab air spring (or shock absorber) and the chassis frame rail, ensuring stable load transfer and precise alignment of the suspension travel path.

Designed for high-stress applications, this bracket plays a vital role in maintaining driving comfort, cabin stability, and long-term durability — especially on rough roads or under heavy loads. It is widely used across Sinotruk’s premium truck platforms that utilize MAN-derived technology, including the HOWO A7, T7H, and SITRAK C7H series.
