Product Introduction
This steering gear assembly is a core component of the steering system for Sinotruk HOWO heavy-duty trucks. It is responsible for converting the rotational motion of the steering wheel into linear motion and amplifying the steering force, realizing precise control of the vehicle's driving direction.
Manufactured with advanced casting, precision machining and heat treatment technologies, the steering gear features high structural strength, good wear resistance and stable transmission performance. The internal gear set is precision-ground to ensure smooth meshing, sensitive steering response and low noise. The advanced sealing design effectively isolates external impurities, ensuring reliable operation in complex road conditions such as long-distance transportation, engineering transportation and bad roads.
Fully compliant with Sinotruk OEM production standards, each steering gear undergoes strict quality testing to ensure stable performance and long service life. It is an essential replacement part for Sinotruk HOWO truck owners and repair shops, effectively solving common faults such as heavy steering, steering delay and gear wear.
Applicable Models
Suitable for all series of Sinotruk HOWO heavy-duty trucks, including HOWO A7, HOWO T7H, HOWO T5G, HOWO 371, HOWO 380, HOWO King Kong, as well as various modified dump trucks, tractors and special vehicles.
