The WG9725470084 power steering gear box is a hydraulic steering system component designed for SITRAK C7H heavy-duty trucks. It converts steering wheel input into precise hydraulic-assisted steering movement, ensuring smooth, stable, and accurate control of the front axle under heavy-load and long-distance operating conditions.
The SITRAK C7H platform is widely used in high-end logistics and freight transport, requiring reliable steering performance under continuous heavy-duty operation. This steering system significantly reduces driver effort while maintaining high steering precision and directional stability.
The housing is manufactured from high-strength cast iron material, ensuring resistance to hydraulic pressure, vibration, and long-term mechanical stress. Internal precision-machined components ensure smooth hydraulic response and long service life.
Each unit is strictly tested for hydraulic sealing, pressure endurance, steering accuracy, and durability to meet OEM standards for heavy-duty commercial vehicles.
