Sinotruk HOWO Series Heavy Truck Subframe/Crossmember

This product is a Sinotruk HOWO series heavy truck subframe/crossmember, commonly known as a front suspension crossbeam. It is a key load-bearing and connecting component of the front axle system of heavy trucks, directly determining the rigidity of the vehicle's front end, load transmission stability, and the reliability of the front axle system. It is compatible with multiple HOWO series heavy truck models, strictly following original factory standards in research and development and production. 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 operation of the front axle system and the front structure of the vehicle.

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

[P_STAR] [T] Core OE Number: AZ9725510059: This number is the original factory standard OE number, clearly marked on the component surface for easy identification, selection, procurement, and replacement. It effectively avoids compatibility errors caused by model confusion, ensuring perfect compatibility with the original vehicle's front axle, engine, frame, 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 the front suspension crossbeam, named for its shape, structure, and installation position. It is exclusively adapted to the Sinotruk Howo series heavy-duty truck front axle system and is the core component between the front axle and the frame.The core connecting hub directly affects the load transfer, overall rigidity, and driving stability of the vehicle's front end. Manufactured strictly according to Sinotruk's original technical parameters, its quality is completely consistent with original parts, combining compatibility and reliability.

II. Core Functions (Load-bearing Connection, Stable Protection)

Connecting and Bearing, Evenly Distributing Load: As the dedicated connection and load-bearing structure between the front axle and the frame, the core bears the load transfer function. It evenly distributes the weight and working load of core components such as the front axle, engine, and transmission onto the frame, avoiding localized load concentration that could lead to frame or front axle deformation or damage, thus improving the overall rigidity and structural stability of the vehicle's front end.

" [ART] Enhanced Rigidity, Adaptable to Complex Working Conditions: Utilizing high-strength materials and precision machining processes, it possesses excellent bending, torsional strength, and fatigue resistance. It can withstand alternating stress and impact loads under complex driving conditions such as heavy truck loads, mountain roads, and bumpy surfaces for extended periods, preventing deformation, cracking, and weld detachment of the subframe itself, ensuring the stability of the front axle system and the front structure of the vehicle.

Precise Alignment, Ensuring Reliable Assembly: Precise mounting holes and positioning structures are reserved. The hole dimensions, spacing, and positioning accuracy strictly adhere to original factory standards, with errors controlled within a reasonable range. This facilitates precise alignment with the front axle, engine, frame, and other related accessories without the need for additional drilling or repositioning, ensuring assembly accuracy and eliminating the risk of loosening after assembly, thus improving the front...Reliability of the bridge system and related components.

Protecting components and extending lifespan: By uniformly transmitting loads and strengthening front rigidity, uneven stress on core components such as the front axle, engine, and transmission is reduced, avoiding wear and failures caused by component connection deviations. Simultaneously, it buffers the impact of road impacts on front components, extending the overall service life of the front axle system, engine, and transmission, and reducing later maintenance costs.

III. Product Structure and Material Characteristics (Precision Manufacturing, Durable and Robust)

Excellent Materials and Outstanding Strength: Made of high-quality, high-strength steel plates through stamping and welding or precision casting of cast steel. Both processes ensure high strength of the components." High performance, uniform material density, excellent toughness, and high hardness, possessing superior bending, torsion, and impact resistance, capable of withstanding repeated testing under complex working conditions for extended periods, and not prone to deformation, cracking, or weld detachment.

Precision machining, exquisite craftsmanship: The steel plate stamping and welding model adopts high-precision stamping and seamless welding processes, resulting in smooth, strong welds with meeting strength standards; the cast steel model is manufactured through multiple processes including precision casting, CNC machining, grinding, and polishing, resulting in a smooth surface without burrs or sand holes, and precise overall dimensions, ensuring a perfect fit and connection accuracy with all related components.

Precise positioning, strong adaptability: Precisely matches multiple heavy-duty truck models such as Sinotruk Howo A7, T7H, TX, and Howo, without requiring...Extra compatibility with modifications, directly replacing old or damaged original parts. The mounting holes and positioning structure perfectly match the original vehicle dimensions, offering strong versatility and convenient installation, significantly reducing repair and replacement time costs.

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 subframe from rusting, corroding, and peeling paint; it also improves surface wear resistance, adapting to 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, Sinotruk HOWO TX, and Haohan, covering different years and heavy-duty configurations within this series. It can directly connect to the original front axle system, perfectly matching the installation dimensions of the front axle, engine, frame, and related accessories. It's ready to install right out of the box, providing a convenient and reliable solution for vehicle repair and parts replacement.

Additional notes: This product uses independent protective packaging to effectively prevent damage such as bumps, scratches, and deformation during transportation and storage. It comes with detailed installation instructions, with clear and easy-to-understand steps, allowing even those without professional repair experience to efficiently complete the installation. Each product...All components undergo rigorous factory quality testing to ensure they meet original factory standards, with strength, precision, and corrosion resistance meeting requirements, providing strong support for the safe and stable operation of the heavy-duty truck front axle system.
