Product Introduction
The AZ9731430020 drag link is a heavy-duty steering linkage component designed for SINOTRUK HOWO truck steering systems. It connects the steering gearbox and steering arm, transmitting steering movement from the steering wheel to the front axle wheels to ensure accurate and stable vehicle steering control.
This drag link assembly is manufactured from high-strength forged steel material with precision-machined ball joint connections, providing excellent resistance against heavy load impact, vibration, and long-term mechanical stress during heavy-duty vehicle operation.
The component is engineered to maintain stable steering geometry and smooth steering response under demanding road and transport conditions. It helps improve driving stability, steering accuracy, and overall operational safety for long-haul logistics, mining, and construction transportation applications.
The drag link is designed according to OEM specifications for direct-fit installation on original HOWO steering systems. Each unit is tested for dimensional accuracy, steering movement performance, durability, and load resistance before shipment to ensure OEM-level quality standards.
