Sinotruk HOWO Series Heavy Truck Steering Rocker Arm

This product is a pair of Sinotruk HOWO series heavy truck steering rocker arms (English: Steering Rocker Arm), also known as steering drop arms. It is a core transmission component of the heavy truck steering system, directly determining the vehicle's steering accuracy, transmission efficiency, and driving safety. It is suitable for the long-distance, heavy-load, and complex road conditions of heavy trucks. Strictly following original factory standards in research and development, it can directly replace old or damaged original factory parts without additional adaptation or modification. It precisely matches the original vehicle dimensions, providing a solid guarantee for the stable and efficient operation of the steering system.

I. OE Number and Product Alias ​​(Precise Correspondence, Original Factory Compatibility)

Core OE Number: Common Core The OE number is QD97192, and it is also compatible with similar models such as AZ9719410040 and AZ9719410041. Different numbers correspond to the left and right steering arms respectively, with clear and easy identification for quick selection, procurement, and replacement. This effectively avoids compatibility errors caused by model confusion and ensures perfect compatibility with original vehicle steering gears, steering tie rods, steering knuckles, and other components. No secondary processing or adjustment is required; it can be installed directly out of the box, significantly improving maintenance and replacement efficiency.

Product Alias: Commonly known as a steering drop arm, exclusively compatible with Sinotruk Howo series.The heavy-duty truck steering system is the core carrier of steering torque transmission. Its quality directly affects steering transmission accuracy, response speed, and driving safety. Manufactured strictly according to Sinotruk's original technical parameters, its quality is completely consistent with original parts, combining adaptability and reliability.

II. Core Functions (Force Transmission Steering, Precise Protection)

Transmitting steering torque to achieve vehicle steering: As the core transmission component of the steering system, it precisely connects the steering gear and steering tie rod, efficiently converting the steering torque output by the steering gear into the reciprocating swing of the rocker arm. This force is then transmitted to the steering knuckle through the steering tie rod, driving the wheels to precisely deflect, achieving flexible and smooth vehicle steering, and ensuring the driver's steering operation." It can quickly and accurately provide feedback to the wheels.

Withstands alternating loads and adapts to complex working conditions: Made of high-strength ductile iron, it undergoes precision casting and professional heat treatment processes (quenching and tempering), possessing excellent strength, rigidity, and impact resistance. It can withstand the alternating loads, steering impacts, and additional forces from road bumps generated during heavy truck operation for extended periods, and is not prone to deformation, cracking, or breakage. It is suitable for the heavy-duty and complex road conditions required for heavy trucks.

Ensures steering precision and enhances handling safety: It adopts a precise hole and angle design. The hole size, spacing, and installation angle strictly follow the original factory standards, with errors controlled within a reasonable range, ensuring proper fit with the steering gear, etc.[T] Pair-pack design, strong adaptability: This product comes in a pair, with precise correspondence between the left and right steering rocker arms. Each arm is matched with a different OE number, perfectly adapting to the installation requirements of the left and right steering systems of heavy trucks. It can directly replace a single or damaged original steering rocker arm without additional accessories. It is compatible with multiple Howo models, offering strong versatility and convenient installation.

Corrosion and wear resistance, extended lifespan: The surface undergoes professional anti-corrosion treatment (galvanizing, painting, or electrophoresis), forming a dense protective coating that effectively resists the erosion of rainwater, dust, mud, corrosive gases, and road salt, preventing the steering rocker arms from rusting and corroding. It is suitable for the complex outdoor driving environment requirements of heavy trucks, significantly extending the product's service life.

IV. Compatible Vehicle Models (Precise Matching, No Adaptation Required)

This product is specifically designed for Sinotruk HOWO series heavy-duty trucks, precisely compatible with the following models: Sinotruk HOWO A7, Sinotruk HOWO T7H, HOWO 336, HOWO 371, HOWO, and other mainstream heavy-duty truck models, covering different years and heavy-duty configurations of this series. Different OE numbers correspond to the left and right steering arms, allowing direct connection to the original vehicle steering system. It perfectly matches the installation dimensions of the steering gear and steering tie rod, and can be installed out of the box, providing a convenient and reliable solution for vehicle maintenance and parts replacement.

Additional Notes: This product uses independent protective packaging, with each pair individually sealed to effectively prevent bumps, scratches, etc. during transportation.Deformation and other damage; comes with detailed installation instructions, the steps are clear and easy to understand, even those without professional repair experience can complete the installation by following the instructions. Furthermore, the product undergoes rigorous factory quality testing, each product meets usage standards, providing strong support for the safe and stable operation of the heavy-duty truck steering system.
