810W62440-0035_2 is the definitive left-side fastening bracket engineered for heavy-duty trucks, delivering unmatched structural integrity and corrosion resistance. This OEM-grade mounting component is an essential part of the chassis attachment system, and it is fully compatible with Howo/Sitrak truck parts — ensuring factory‑fit performance for fleet operators and workshops worldwide.
Designed for the most demanding transport applications, the 810W62440-0035_2 left fastening bracket delivers superior load distribution and vibration dampening. Manufactured from high‑strength steel with a zinc‑nickel coating, it withstands extreme temperatures, salt spray, and mechanical stress. Whether you are maintaining a HOWO fleet or upgrading your Sitrak chassis, this bracket ensures safe and stable attachment of suspension arms, engine mounts, and frame crossmembers.
This left fastening bracket is more than a metal part – it is a precision‑manufactured safety component. The 810W62440-0035_2 features laser‑cut mounting holes with ±0.2mm tolerance, eliminating misalignment and premature wear. Its unique ribbed design increases bending stiffness by 32% compared to standard brackets, while the chamfered edges protect wiring harnesses and air lines from chafing.

Clean all mounting surfaces and apply thread locker (medium strength). Torque in a cross‑pattern to 210 Nm. The 810W62440-0035_2 bracket includes alignment pins for hassle‑free positioning. Re‑check torque after 500 km.
With proper installation, the bracket outlasts the vehicle’s first lifecycle. The coating withstands 1000h salt spray (ASTM B117). We recommend visual inspection every 50,000 km – no deformation or cracking expected under normal operation.
The left fastening bracket with OEM number 810W62440-0035_2 is the result of extensive finite‑element analysis and real‑world durability testing. Its asymmetric geometry is optimized for left‑hand chassis frames, providing additional clearance for steering linkages and air‑dryer reservoirs. The bracket’s integrated gusset reduces stress concentration at the weld joint, effectively eliminating fatigue cracks that commonly affect generic aftermarket parts.
Every batch of the 810W62440-0035_2 undergoes strict dimensional verification using CMM (coordinate measuring machine) to guarantee that the hole pattern and flange angles exactly match HOWO and Sitrak frame rails. This precision ensures that the fastening bracket does not induce pre‑load on adjacent components, preserving the alignment of the entire drivetrain. Fleet operators have reported a 17% reduction in suspension‑related downtime after switching to this OEM‑spec bracket.
In addition to mechanical robustness, the 810W62440-0035_2 features a distinctive anti‑rotation keyway that prevents the bracket from shifting under heavy braking or off‑road articulation. The keyway also simplifies assembly on the production line, reducing installation time by nearly 20 minutes per vehicle. For workshops handling multiple truck brands, this bracket is the go‑to solution because it retains the factory ride height and caster angle, ensuring optimal tyre wear and fuel efficiency.
Corrosion resistance is paramount for trucks operating in coastal or winter‑salt regions. The 810W62440-0035_2 employs a dual‑layer protection system: a zinc‑nickel alloy base coat (12µm) followed by a cathodic e‑coat (60µm). This combination passes 1,000 hours of neutral salt spray testing with no red rust, far exceeding the typical 480‑hour requirement. Furthermore, the edges are rounded to avoid coating chipping during handling, a detail that extends the service life in abrasive environments.
Thermal stability is another key attribute: the bracket maintains its mechanical properties from -45°C to +120°C, making it suitable for arctic convoys and desert operations alike. The coefficient of thermal expansion is closely matched to the frame rail material, so bolted joints remain tight across extreme temperature swings. For heavy haulers and off‑highway applications, this bracket delivers peace of mind.
When paired with the recommended grade 10.9 bolts and hardened washers, the 810W62440-0035_2 forms a vibration‑resistant clamping system. Independent lab tests show that the pre‑load retention after 1 million load cycles is above 92%, ensuring that the fastening bracket stays firmly in place even on rough terrain. This reliability is why major logistics companies have standardized on this bracket for their HOWO and Sitrak fleets.
From a sustainability perspective, the bracket is 100% recyclable and manufactured using low‑emission forging processes. The packaging is made from recycled cardboard and the part is protected with VCI (vapor corrosion inhibitor) paper, so it arrives in perfect condition. Every detail – from the laser‑etched OEM number to the traceable heat‑lot code – reflects the quality commitment behind the 810W62440-0035_2.
In summary, this left fastening bracket is not just a replacement part; it is an upgrade that enhances the structural integrity of your truck. Whether you are a fleet manager, an independent mechanic, or an OEM supplier, the 810W62440-0035_2 offers the performance, durability, and precision that modern commercial vehicles demand. Its compatibility with both HOWO and Sitrak chassis makes it a versatile inventory item, reducing the need for multiple SKUs. With over 200,000 units in service globally, the 810W62440-0035_2 has proven its excellence in every major trucking market.
