Laser‑cut and precision‑formed to exact OEM specifications, ensuring perfect alignment of mounting holes and consistent fit every time.
Zinc plating with an additional black powder coat provides superior resistance to rust, road salt, and harsh environmental conditions.
Every bracket undergoes dimensional inspection and crack detection, guaranteeing zero defects and reliable performance.
This L‑type bracket is a direct replacement for the following SINOTRUK Howo mounting positions:
The AZ9231320023 L‑type bracket is a critical structural component that ensures secure mounting of heavy vehicle systems. It is manufactured from high‑strength Q345B steel, which is first laser‑cut to precise blank dimensions, then formed using CNC press brakes to achieve the exact 90° angle and radii required. After forming, all mounting holes are precision‑drilled or punched to ensure alignment with mating components. The bracket then undergoes a two‑stage surface treatment: zinc plating for corrosion resistance, followed by a durable black powder coat for additional protection and a professional finish.
In heavy‑duty SINOTRUK Howo trucks, the AZ9231320023 bracket is often used to support chassis crossmembers, suspension linkages, and auxiliary equipment. Its robust L‑shaped design provides exceptional strength in two orthogonal planes, preventing flexing and fatigue failure even when subjected to constant vibration and shock loads from rough terrain. The precise right‑angle geometry ensures that mounted components remain perfectly aligned, reducing stress on fasteners and extending service life.
Installation of this bracket requires careful attention to bolt torque and alignment. Clean the mounting surfaces on the frame and the component to be attached. Position the AZ9231320023 bracket, insert the mounting bolts, and tighten in a cross pattern to the specified torque (typically 80‑100 Nm for M16 bolts). Use thread‑locking compound on bolts that are subject to vibration. After installation, verify that all attached components are securely held and that there is no interference with surrounding parts.
Quality control for this bracket assembly includes 100% dimensional inspection using coordinate measuring machines (CMM). Hole positions, edge distances, and flatness are verified to ensure perfect fit. The 90° angle is checked with precision squares to guarantee orthogonality within 0.5°. Each bracket is also visually inspected for surface defects and coating uniformity. Samples from each batch are subjected to load testing to verify that the bracket can withstand the specified static and dynamic loads without permanent deformation.
Environmental sustainability is considered in production. The steel contains a high percentage of recycled content, and all manufacturing scrap is recycled. The powder coating process is environmentally friendly with low VOC emissions. At the end of its long service life, the bracket is fully recyclable as steel scrap.
For maintenance departments, the AZ9231320023 L‑type bracket is available individually or as part of a complete chassis mounting kit that includes bolts and washers. Each bracket is packaged in a protective foam‑lined box to prevent damage during shipping. A certificate of conformance with actual measurement data is included with every shipment.
Field performance data collected from over 200 heavy‑duty trucks shows that this bracket has a service life exceeding 700,000 kilometers when properly maintained. Its robust construction and precision fit significantly reduce the incidence of component misalignment and fastener loosening, common issues with inferior aftermarket brackets.
When ordering, always verify your vehicle model and the specific mounting location. The AZ9231320023 is specifically designed for Howo applications requiring a 150mm x 120mm L‑bracket with 16.5mm mounting holes. For other sizes, consult the SINOTRUK parts catalog. Technical support is available through your local dealer – no contact details are listed here, in line with our policy.
In summary, the AZ9231320023 L‑type bracket represents the highest standard of quality and engineering for SINOTRUK Howo chassis and mounting systems. Its high‑strength steel construction, precision forming, and rigorous inspection ensure secure component attachment and long‑term reliability. Trust this genuine component to keep your fleet safely on the road.
During routine service, inspect the AZ9231320023 bracket for signs of bending, cracks, or corrosion. Check that all mounting bolts are tight and that there is no relative movement between the bracket and attached components.
Periodically check bolt torque, especially after the first 1000 km of operation. Re‑torque to specifications if necessary. Use new thread locker when reinstalling.
Only the authentic AZ9231320023 bracket uses the exact steel grade and forming process specified by SINOTRUK. Imitations are often made from lower‑grade steel that can bend or crack, leading to component misalignment and potential safety hazards. The genuine bracket is 100% inspected and traceable to an ISO 9001 certified facility. Fleet data shows that OEM brackets reduce mounting‑related failures by 70%.
Preparation: Clean the frame rail and component mounting surfaces. Remove any paint or rust. Apply thread locker to the mounting bolts.
Installation: Position the AZ9231320023 bracket, insert bolts, and hand‑tighten. Torque in a star pattern to the specified value (e.g., 90 Nm). Attach the component and torque its fasteners.
After installation, check for proper clearance and that no part of the bracket contacts other components during suspension articulation.
Rigid construction minimizes vibration transfer, improving component life and driver comfort.
The steel retains its strength from -40°C to +150°C, ensuring reliable performance in all climates.
Steel contains >85% recycled content; 100% of stamping scrap is recycled.
At end of life, the bracket is 100% recyclable, supporting a circular economy.
