WG9725593016 Auto Spare Heavy Truck Part New Steel Engine Carrier Replacement for HOWO Weichai FAW Shacman Dongfeng

The SINOTRUK WG9725593016 Engine Rear Support (also known as Engine Rear Mounting Bracket) is an original equipment (OE) structural component manufactured by China National Heavy Duty Truck Group (SINOTRUK). Designed as a critical load-bearing interface between the engine and vehicle chassis, this bracket provides stable rear support for heavy-duty diesel engines — ensuring proper alignment and minimizing dynamic displacement during operation.

Primarily used on HOWO 7, HOWO A7, Hohan, and Golden Prince series trucks, it plays a vital role in maintaining drivetrain integrity under high-torque conditions such as hill climbing, heavy hauling, or off-road operation. The support assembly works in conjunction with rubber vibration isolators to absorb engine vibrations, reduce noise transmission into the cab, and protect downstream components like the driveshaft, radiator, and exhaust system.
