Sinotruk HOWO Series Heavy Truck Front Leaf Spring Rear Bracket

This product is a front leaf spring rear bracket for Sinotruk HOWO series heavy trucks. The front suspension (bracket) is a key installation and load-bearing component of the heavy-duty truck's front suspension system. It directly determines the installation stability, positional accuracy, and operational reliability of the front leaf springs and the suspension system. Adapted to the long-distance, heavy-load, and complex road conditions required for heavy-duty trucks, it is developed and manufactured strictly according to original factory standards. It can directly replace old or damaged original factory parts without additional adaptation or modification, precisely matching the original vehicle dimensions, providing a solid guarantee for the stable and efficient operation of the front suspension system.

I. OE Number and Adaptor Marking (Precise Correspondence, Original Factory Adaptation)

Core OE Number: WG9731520065/2: This number is the original factory standard OE number, clearly marked on the component surface for quick identification, selection, procurement, and replacement. It effectively avoids adaptation errors caused by model confusion, ensuring perfect compatibility with the original vehicle's front leaf springs, 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.

Auxiliary Number: 20057G / ID:0AG01: In addition to the core OE number,The component is also marked with auxiliary numbers 20057G and ID:0AG01, serving as supplementary identifiers for compatibility verification. This further ensures the accuracy of the part selection and compatibility with various mainstream heavy-duty truck models such as Sinotruk Howo A7, Howo T7H, Howo TX, and Howohan, covering different years and heavy-duty configurations within this series.

II. Core Functions (Installation and Fixing, Stable Protection)

Securely Install Front Leaf Springs: As a dedicated mounting base for the rear end of the front leaf springs, it can firmly fix the rear end of the front leaf springs to the frame, accurately positioning the installation position of the leaf springs, ensuring the positional accuracy and installation stability of the leaf springs, and preventing the leaf springs from shifting or loosening during vehicle operation." This design ensures the front suspension system operates precisely without detachment or movement, laying a solid foundation for its accurate operation.

Load Bearing and Shock Absorption: Utilizing high-strength materials and precision machining processes, it possesses excellent strength and rigidity, effectively withstanding the enormous loads and alternating stresses generated by the front leaf springs during operation, as well as the impact forces from road bumps during vehicle travel. This prevents deformation, cracking, or breakage of the bracket due to excessive loads or impacts, ensuring the structural strength and operational stability of the front suspension system.

Ensuring Assembly Precision and Enhancing Reliability: Precise mounting holes and positioning structures are provided. The hole dimensions, spacing, and positioning accuracy strictly adhere to original factory standards, with errors controlled within a reasonable range, facilitating connection with the front leaf springs and other components.The frame and other related accessories achieve precise docking, eliminating the need for additional drilling or repositioning, ensuring the overall vehicle assembly precision, improving the operational reliability of the front suspension system, and reducing wear between components.

Supporting the suspension system and improving ride comfort: By stabilizing and fixing the front leaf springs, the leaf springs assist in their damping and shock absorption functions, reducing vehicle body bumps and swaying during driving, mitigating the impact of shocks on the frame and body, improving ride comfort, and protecting all related components of the front suspension system, extending their service life.

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

Superior Materials, Outstanding Strength: Utilizing high-quality, high-strength balls..." Made from precision-cast iron or cast steel, both materials possess uniform density, excellent toughness, and high hardness. Through rigorous heat treatment processes (quenching and tempering), the strength, rigidity, and fatigue resistance of the bracket are further enhanced. It can withstand repeated testing under complex working conditions for extended periods, and is less prone to wear, cracking, deformation, and other failures, ensuring load-bearing safety.

Precision machining, meeting accuracy standards: Manufactured through multiple processes including precision casting, CNC machining, and polishing, the surface is smooth, burr-free, and free of sand holes. The mounting holes and positioning structure are precise, with minimal dimensional errors, ensuring a close fit and precise connection with the front leaf spring and frame. There is no risk of loosening after assembly, guaranteeing the bracket's installation stability and load-bearing reliability.

Precise positioning and strong adaptability: Precisely matches multiple models in the Sinotruk Howo series, requiring no additional adaptation or modification. It can directly replace old or damaged original parts. The mounting holes and positioning structure perfectly align with the original vehicle dimensions, adapting to various models such as the Howo A7 and T7H. It boasts 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 bracket from rusting and corroding. It adapts to the complex outdoor driving needs of heavy trucks, significantly extending the product's service life.

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 of this series. It can directly connect to the original vehicle's front suspension system, perfectly matching the front leaf springs and frame installation dimensions. It can be installed immediately upon opening the box, providing a convenient and reliable solution for vehicle maintenance and parts replacement.

Additional Notes: This product uses independent protective packaging to effectively prevent damage such as bumps, scratches, and deformation during transportation; it comes with detailed installation instructions, with clear and easy-to-understand steps.Even without professional repair experience, installation can be completed by following the instructions. Furthermore, the products undergo rigorous factory quality testing, and each unit meets usage standards, providing strong support for the safe and stable operation of the heavy-duty truck front suspension system.
