WG9925590270 Engine Front Support Use for SINOTRUK HOWO HOHAN FAW SHACMAN DONGFENG BEIBEN FOTON Spare Parts Engine Front Mounting Cushion / Front Engine Mount

The WG9925590270 Front Engine Mounting Cushion Assembly, officially known as the Engine Front Rubber Bearing or Front Motor Mount, is a high-performance vibration-isolation component designed for SINOTRUK commercial vehicles built on MAN (German MAN) technology platforms, particularly the premium SITRAK C7H, G7, G5, and MAX series.

This mounting pad connects the front end of the engine to the chassis frame, serving dual functions:

Structural support for the engine’s front weight
Dynamic damping of engine vibrations and torque shocks
Unlike traditional steel-bodied mounts, this version features an aluminum housing combined with high-damping natural rubber, offering superior corrosion resistance, lightweight performance, and enhanced NVH (Noise, Vibration, Harshness) control. It plays a critical role in improving driver comfort, reducing cabin noise, and protecting drivetrain components from misalignment damage during operation.
