Sinotruk HOWO Series Heavy Truck Rear Leaf Spring Slide Rail / Guide Plate

This product is a Sinotruk HOWO series heavy truck rear leaf spring slide rail / guide plate (English: Rear Leaf Spring Slide Rail / Guide) The leaf spring plate (OE plate) is a key guiding and supporting component of the heavy-duty truck suspension system. It directly determines the smoothness of the rear leaf spring's sliding, the degree of wear, and the reliability of the suspension system. It is compatible with Howo 08 model, Steyr, and other heavy-duty trucks. Developed and manufactured strictly according to original factory standards, it can directly replace old or damaged original 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 suspension system.

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

Core OE Number: AZ9725520250: 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 compatibility errors caused by model confusion, ensuring perfect compatibility with the original rear leaf spring and frame. No secondary processing or adjustment is required; it can be installed directly out of the box, significantly improving maintenance and replacement efficiency.

Compatible Models: Specifically designed for heavy-duty trucks.Model design, precisely adapted to mainstream heavy-duty truck models such as Sinotruk Howo 2008 and Steyr, covering different years and heavy-duty configurations in this series. It boasts strong adaptability and can directly connect to the original vehicle suspension system without additional modifications, meeting the needs of heavy-duty and long-distance driving.

II. Core Functions (Guiding Support, Smooth Driving)

Guiding Sliding, Ensuring Suspension Smoothness: As the dedicated sliding support surface for the rear leaf spring, it plays a core guiding and supporting role, guiding the rear leaf spring to slide smoothly up and down when the vehicle load changes or the road surface is bumpy, preventing leaf spring offset and jamming, ensuring flexible operation of the suspension system, and guaranteeing smooth vehicle driving.

" [ART] Reduced Friction and Lower Component Wear: The smooth support surface design effectively reduces the frictional resistance between the rear leaf spring and the bracket during sliding, reducing wear on both and preventing deformation and damage to the leaf spring due to excessive friction, thus extending the service life of the rear leaf spring and related suspension system components.

Load-Bearing and Pressure-Resistant, Adaptable to Complex Working Conditions: Made of high-strength wear-resistant cast iron, precision-cast and professionally processed, it possesses excellent wear resistance and compressive strength. It can withstand the enormous friction generated by the repeated sliding of the rear leaf spring, as well as the load pressure of the vehicle body and cargo, without easily experiencing wear, deformation, or breakage. It is suitable for heavy-duty trucks and complex road conditions.

[RT] Precise Alignment, Enhanced Assembly Reliability: Precise mounting holes are reserved, with hole dimensions and spacing strictly adhering to original factory standards. Errors are controlled within a reasonable range, facilitating precise alignment with the chassis without additional drilling or repositioning. This ensures assembly accuracy, eliminates the risk of loosening after assembly, and improves the operational reliability of the suspension system.

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

Superior Material, Wear-Resistant and Pressure-Resistant: Made of high-quality, high-strength, wear-resistant cast iron through precision casting, the material has uniform density and excellent toughness, possessing superior wear resistance and compressive strength. Professional processing further enhances the surface smoothness of components, reducing friction loss and enabling long-term withstand of complex... Repeated testing under various working conditions minimizes the risk of wear, deformation, and cracking.

Precision machining, accurate guidance: Manufactured through precision casting, CNC machining, grinding, and polishing, the surface is smooth, burr-free, and free of sand holes. The sliding support surface has high flatness and strong guidance, ensuring smooth sliding of the rear leaf springs, preventing jamming and misalignment, and guaranteeing the flexible operation of the suspension system.

Precise positioning, strong adaptability: Accurately matches Howo 08 model, Steyr, and other heavy-duty truck models, requiring no additional adaptation or modification. It can directly replace old or damaged original parts. The mounting holes precisely align with the original vehicle frame dimensions, offering strong versatility and convenient installation, significantly reducing maintenance and replacement time costs.

Corrosion and wear resistant, extended lifespan: The surface undergoes professional anti-corrosion treatment (galvanizing, painting, or electrophoresis) to form a dense protective coating, effectively resisting the erosion of rainwater, dust, mud, corrosive gases, and road salt, preventing rust and corrosion of the slide rails/guide plates, adapting to the complex outdoor driving needs of heavy trucks, and further extending the product's service life.

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

This product is specifically designed for certain heavy truck models, precisely compatible with the following models: Sinotruk Howo 2008 model, Steyr, and other mainstream heavy truck models, covering different years and heavy-duty configurations of this series. It can be directly connected to the original vehicle suspension system, perfectly matching the rear leaf springs and frame mounting dimensions. 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. It comes with detailed installation instructions; the steps are clear and easy to understand, allowing even those without professional repair experience to complete the installation. Furthermore, the product undergoes rigorous factory quality testing, and each item meets original factory standards, providing strong support for the safe and stable operation of the heavy-duty truck suspension system.
