OEM WG9725520279/WG9725520277 • Left + right pair • High-strength steel • Corrosion resistant • Direct OEM fit
The Support Bracket (L+R) is a critical structural component on SINOTRUK Howo trucks, used to mount and support the cab, engine, transmission or suspension assemblies. It connects the component to the chassis frame, maintaining correct alignment and isolating vibration. A damaged or corroded bracket can cause excessive movement, misalignment and premature wear of connected parts.
This WG9725520279/WG9725520277 bracket pair is precision-manufactured to exact OEM dimensions. The mounting holes are drilled to the correct pattern, the surfaces are machined flat for proper contact, and the gussets are welded for strength. The coating resists rust and corrosion from road salt, mud and moisture.
Common signs that a support bracket needs replacement include visible cracks or bends, elongated mounting holes, loose or missing fasteners, excessive vibration from the mounted component, and rust or corrosion that weakens the structure. Fitting a new WG9725520279/WG9725520277 bracket pair restores proper support and alignment.
Whether you are repairing accident damage, replacing a worn bracket or carrying out preventive maintenance on a fleet of Howo trucks, the WG9725520279/WG9725520277 Support Bracket (L+R) delivers the strength, fit and durability that SINOTRUK Howo professionals expect.
The WG9725520279/WG9725520277 Support Bracket (L+R) is designed for SINOTRUK Howo trucks, with primary compatibility across the A7, T7H, HOWO 371 and HOWO 380 series. It is a direct OE replacement, so it bolts to the factory chassis frame and connects to the original component mounting points without modification.
This bracket pair is essential in applications where structural reliability and vibration isolation are critical, such as long-haul transport, construction, mining and municipal service. In these duties, the brackets must support heavy loads, resist shock and fatigue, and maintain correct alignment of the mounted component.
When replacing the support brackets, it is recommended to inspect the chassis frame, mounting bolts, bushings and the mounted component for wear or damage. The WG9725520279/WG9725520277 is designed to work with the factory components, ensuring proper alignment and a secure installation. It is suitable for both standard and heavy-duty chassis configurations.
For fleets with multiple HOWO trucks, standardising on the WG9725520279/WG9725520277 simplifies chassis repair inventory and ensures the correct brackets are available for scheduled maintenance or emergency repairs.
Replacing the WG9725520279/WG9725520277 Support Bracket (L+R) is a moderately complex procedure that requires mechanical expertise and appropriate tools. This work should be performed by qualified technicians with experience in heavy-duty chassis systems. Begin by safely raising the vehicle and supporting the chassis on stands.
Support the mounted component with a jack or crane to relieve the load on the brackets. Remove the mounting bolts and withdraw the old brackets. Inspect the chassis frame and component mounting points for cracks, corrosion or elongation. Clean the mounting surfaces and check the new brackets for correct fit.
Position the new WG9725520279/WG9725520277 brackets on the chassis and component, aligning the mounting holes. Insert the bolts and torque them to the specified value. Lower the component and remove the support. Check that the brackets are correctly seated and that all fasteners are tight.
After installation, road-test the vehicle and check for unusual noises or movement. Re-torque the mounting bolts after the first few hundred kilometres. For ongoing maintenance, inspect the brackets at every major service for cracks, corrosion or loose fasteners, and replace them if any defect is found.
The WG9725520279/WG9725520277 Support Bracket (L+R) is manufactured in an ISO 9001-certified facility using advanced stamping, forming, welding and coating processes. Raw steel is sourced from certified suppliers and tested for thickness, strength and weldability before production.
Each bracket is precision-built to exact OEM dimensions. The mounting holes are checked for correct pattern and diameter, the surfaces are inspected for flatness, and the welds are tested for penetration and continuity. The coating is checked for coverage and adhesion to ensure long-term corrosion protection.
Random samples from each production batch undergo load testing, fatigue testing and salt-spray testing to validate long-term reliability under real-world conditions. These tests ensure the WG9725520279/WG9725520277 continues to provide secure support throughout its service life.
We back the WG9725520279/WG9725520277 with a comprehensive 12-month warranty against material and workmanship defects. Our rigorous quality control ensures that every support bracket delivers the same fit, strength and durability as the original factory component.
The WG9725520279/WG9725520277 Support Bracket (L+R) is a critical structural component for your Howo truck.
