Original Dongfeng GX Protective net under bumper 8406038-C6200

Constructed from dual-layer galvanized steel (mesh wire diameter: 2.8mm; frame thickness: 3.2mm), the 8406038-C6200 protective net delivers exceptional strength and corrosion resistance. The galvanized steel mesh boasts a tensile strength of ≥600 MPa, withstanding direct impacts from 600g rocks at 45 km/h without tearing or deformation. The frame undergoes an advanced four-step anti-corrosion treatment: zinc phosphate pretreatment (14-16μm), electrophoretic primer (20-24μm), epoxy mid-coat (15-18μm), and black polyester powder coating (75-85μm). This system passes 1500-hour neutral salt spray tests without red rust, ensuring durability in coastal (saltwater), snowy (road salt), or industrial (chemical debris) environments. The robust build guarantees a service life of over 9 years—outperforming plastic or low-grade aluminum alternatives by 50%

Unlike solid under-bumper guards that restrict airflow, the 8406038-C6200 protective net is engineered to maintain the GX’s under-hood cooling performance. Its open mesh structure (82% air permeability) allows unobstructed airflow to the radiator, intercooler, and front brakes, keeping under-hood temperatures within optimal ranges (≤92°C for engine coolant) during heavy loads or high-speed driving (up to 120 km/h). Computational fluid dynamics (CFD) testing shows the net causes only a 1.5% reduction in airflow compared to an uncovered bumper—far below the 20% reduction of solid guards. This design prevents engine overheating, a critical advantage for long-haul trucks operating in hot climates or hauling maximum-weight cargo

Exclusively tailored for Dongfeng GX heavy-duty trucks (including cargo, long-haul, and dump variants), the 8406038-C6200 protective net strictly adheres to original equipment (OE) specifications. Manufactured using 3D laser scanning of the GX’s under-bumper area and CNC precision bending for the frame, it achieves dimensional accuracy within ±0.15mm—matching every curve, contour, and mounting point of the bumper’s lower edge. The net includes 10 pre-drilled mounting holes (M8 threaded, 13mm depth) that align perfectly with the GX’s factory under-bumper brackets, eliminating gaps that could allow debris infiltration. It is fully compatible with all Dongfeng GX models produced since 2022, including those with bumper-mounted tow hooks, fog lights, or auxiliary cooling fans (featuring precision cutouts for these components), requiring no drilling or modification

The 8406038-C6200 protective net is designed for hassle-free installation and minimal upkeep, ideal for truck fleets. It comes with a complete hardware kit: 10 grade 10.9 high-strength bolts, lock nuts, stainless steel washers, and rubber gaskets (to prevent frame-bumper scratches). The lightweight design (4.5kg) and laser-engraved mounting marks allow two technicians to install it in 25-30 minutes, accessing the under-bumper area via standard vehicle jack points (no disassembly of major components needed). For maintenance, the mesh can be cleaned with a pressure washer or stiff brush to remove mud, gravel, or debris—no special tools or cleaning agents required. The powder-coated frame resists scratches and stains, maintaining a professional appearance with minimal effort, while the galvanized mesh avoids rust-related maintenance issues
