Dongfeng GX Left headlight bracket assy 8406131-C6200

Constructed from 2.8mm-thick high-strength cold-rolled steel (CR500 grade)—reinforced with 3mm-thick welded ribs at stress points—the 8406131-C6200 assembly balances rigidity and impact resistance. The steel exhibits a tensile strength of ≥500 MPa, enabling it to withstand minor front-end impacts (e.g., debris collisions or low-speed scrapes) without bending or cracking. Finite element analysis (FEA) optimizes the rib layout, distributing stress evenly across the frame to prevent deformation under load (e.g., when mounting auxiliary lighting). Unlike plastic alternatives, it resists warping from extreme temperatures: maintaining shape at -35°C (cold climates) and 90°C (engine bay heat). This durability guarantees a service life of over 8 years, outperforming plastic bracket assemblies by 250% in harsh conditions

Exclusively tailored for Dongfeng GX heavy-duty trucks (cargo, long-haul, dump variants), the 8406131-C6200 assembly adheres strictly to original equipment (OE) specifications. Manufactured using 3D laser scanning of the GX’s front frame and headlight housing, it achieves dimensional accuracy within ±0.08mm—matching every mounting hole, contour, and connection feature of the factory design. The assembly includes five pre-drilled M6 threaded holes (depth: 11mm) that align perfectly with the GX’s front frame rails and headlight adjustment mechanisms, eliminating gaps that cause rattling or water infiltration. It integrates seamlessly with the truck’s original headlight leveling system, ensuring no compromise on factory-calibrated light aim—critical for compliance with road safety regulations

To combat rust and degradation from road salt, rain, and industrial debris, the 8406131-C6200 assembly undergoes a four-step OE-grade anti-corrosion process. First, a zinc phosphate pretreatment (15-17μm thick) creates a porous base for coating adhesion. Second, an electrophoretic primer (20-22μm thick) provides uniform coverage—even in hard-to-reach weld joints—blocking moisture. Third, an epoxy mid-coat (18-20μm thick) adds a chemical barrier. Finally, a matte-black polyester powder coating (75-85μm thick) meets ISO 10289 standards, passing 1200-hour neutral salt spray tests without red rust. This protection ensures the assembly maintains structural integrity in coastal (saltwater), snowy (road salt), or industrial areas, avoiding premature failure from corrosion

The 8406131-C6200 assembly is designed for efficient, error-free installation—ideal for fleet maintenance teams. It includes a complete OE-spec hardware kit: five grade 10.9 high-strength bolts (with anti-loosening nylon washers), five lock nuts, and three rubber anti-vibration gaskets (shore hardness: 60±5A) that reduce metal-to-metal friction. Installation requires only standard hand tools (10mm socket wrench) and can be completed by one technician in 18-25 minutes: align the assembly with the front frame, secure bolts to 28±3 N·m (per Dongfeng torque specs), and connect the wiring guides. The kit includes a color-coded installation guide with torque values and alignment marks, minimizing errors. The assembly’s lightweight design (1.2kg) simplifies handling, while its powder-coated surface resists scratches—preserving a professional fleet appearance
