Sinotruk HOWO Series Heavy Truck Original Lower Thrust Rod Assembly (Torque Bar)

This product is a dedicated original lower thrust rod assembly for Sinotruk HOWO series heavy trucks, commonly known as a torsion bar. It is a key load-bearing and force-transmitting component of the chassis suspension system. Its core function is to connect the axle and the frame, accurately transmitting the force and torque between them, directly determining the axle positioning accuracy, chassis stability, and vehicle driving safety. The product is manufactured strictly according to Sinotruk's original molds and production processes, with standardized structure and quality. It can directly replace old or damaged original parts without additional adaptation or modification, providing a solid guarantee for the stable and efficient operation of the chassis suspension system.

OE Model: AZ9631523175: The product's OE model is clearly marked on the pole, allowing for quick identification, selection, procurement, and replacement. This effectively avoids compatibility errors caused by model confusion, ensuring perfect compatibility with the original chassis suspension system, axles, and frame. Strictly adhering to original factory specifications, no secondary processing or adjustment is required; it can be installed immediately upon unpacking, significantly improving maintenance and replacement efficiency.

Compatible Models: Exclusively compatible with multiple heavy-duty truck models from China National Heavy Duty Truck Group (CNHTC), including Howo A7, Howo T7H, Howo T5G, Howo 336, Howo 380, Steyr, etc., covering mining and construction sites.For various application scenarios such as long-distance transportation and heavy-duty operations, it has wide adaptability and can perfectly connect with the chassis structure of various models to meet the force and torque transmission requirements between the axle and the frame.

II. Structural Type and Installation Position (Precision Manufacturing, Strong Adaptability)

Structural Type: Adopts a split structure design, belonging to a dedicated lower thrust rod assembly. The structure is scientific and reasonable, with a compact layout, balancing force transmission accuracy and buffering performance; both ends are equipped with high-quality rubber core ball joints, which can flexibly withstand multi-directional torque and impact forces, avoiding excessive force in one direction that could damage components, while reducing rigid impact during force transmission, improving operational stability, and preventing malfunctions such as looseness and jamming."

Installation Location: Precisely installed between the axle and the frame, primarily used in the rear axle area. It is a core component for rear axle positioning and stability, effectively limiting axle displacement by transmitting longitudinal and lateral forces. This ensures the axle maintains correct positioning during vehicle driving, turning, braking, and heavy load conditions, preventing axle offset and swaying, and guaranteeing the normal operation of the chassis suspension system.

III. Core Product Features (Original Factory Quality, Durable and Efficient)

Precise Force Transmission, Reliable Positioning: The core component possesses precise force transmission capabilities, efficiently transmitting longitudinal and lateral forces between the axle and the frame, effectively limiting the axle's forward/backward and left/right displacement, ensuring the axle maintains correct positioning under various driving conditions.Correct positioning avoids problems such as tire wear and vehicle deviation caused by axle misalignment, improving vehicle stability and safety.

Buffering and shock absorption enhances the driving experience: The rubber core ball joints at both ends provide excellent buffering and shock absorption, effectively absorbing the impact and vibration generated by road bumps, turning, and braking during vehicle operation. It isolates the rigid transmission between the axle and the frame, reducing the feeling of bumps and operating noise during vehicle operation, while protecting chassis components, reducing wear, and improving driving comfort.

Durable and reliable, suitable for harsh working conditions: The pole body is made of high-quality, high-strength alloy steel in one piece, with high strength, excellent toughness, wear resistance, and durability, capable of withstanding heavy loads and high frequencies for extended periods." The force and torque transmission is excellent, making it less prone to bending, cracking, and other malfunctions. The rubber cores at both ends possess excellent oil resistance, water resistance, and high and low temperature resistance, adapting to various harsh working environments such as mines, construction sites, high altitudes, extreme cold, and extreme heat. It is not prone to aging or deformation and has a long service life.

Original factory quality, easy installation: Manufactured using original molds and production processes from China National Heavy Duty Truck Group (CNHTC), the quality meets original factory standards. The appearance is neat, the dimensions are precise, and it perfectly fits the original chassis, axle, and frame mounting positions. Installation is simple and quick, requiring no additional drilling or modification. It can directly replace the old original lower thrust rod assembly, and after installation, it can normally perform its force transmission and positioning functions. It is suitable for heavy truck repair, parts replacement, and bulk procurement needs.

This product is a genuine original part from China National Heavy Duty Truck Group (CNHTC). It features independent protective packaging to effectively prevent damage such as bumps, squeezing, rust, and deformation during transportation and storage. Detailed installation instructions are included, with clear and easy-to-understand steps, allowing even those without professional repair experience to complete installation efficiently. Each product undergoes rigorous factory quality testing to ensure that the pole strength, rubber core elasticity, ball joint flexibility, dimensional accuracy, and other indicators meet standards, providing strong support for the stable operation of the vehicle chassis suspension system, precise axle positioning, and improved driving safety.
