Steering Box WG9725478118 for HOWO Heavy Duty Truck Power Steering System

This steering box (steering gear) with part number WG9725478118 is specially designed for HOWO heavy duty trucks. As the core component of the power steering system, it converts the driver’s steering wheel input into wheel movement, amplifying torque to easily turn the heavy truck’s front wheels.

Made of high-strength ductile iron casting with precision-machined internal components, it features a recirculating ball mechanism for smooth and efficient power transfer. The integrated hydraulic valve system provides precise steering response and reliable power assist. The robust construction is specifically engineered to withstand the high steering loads encountered in heavy duty on-road and off-road applications, delivering consistent steering performance under full load conditions.
