Product Introduction

The WG9725470080 power steering gear box is a hydraulic steering system component designed for SINOTRUK HOWO 371 and HOWO A7 heavy-duty trucks. It is responsible for converting steering wheel input into precise hydraulic-assisted steering movement, ensuring smooth and stable control of the front axle under heavy load conditions.

This steering gear box uses a hydraulic assist mechanism to reduce steering effort, especially during low-speed operation, heavy cargo conditions, and complex road environments. It significantly improves driving comfort and steering accuracy while maintaining strong directional stability.

The housing is manufactured from high-strength cast material to ensure durability under continuous hydraulic pressure and heavy-duty usage. Internal precision-machined components ensure accurate steering response and long-term operational reliability.

Each unit is strictly tested for hydraulic sealing performance, pressure resistance, steering accuracy, and durability to meet OEM standards for heavy truck applications.
