Dongfeng GX Protective net under bumper 8406038-C6100

Constructed from a dual-layer structure—galvanized steel mesh (wire diameter: 2.5mm) and a powder-coated steel frame (thickness: 3mm)—the 8406038-C6100 protective net balances flexibility and rigidity. The galvanized steel mesh exhibits excellent tensile strength (≥550 MPa) and impact resistance, withstanding direct hits from 500g rocks at 40 km/h without tearing. The steel frame undergoes a three-step anti-corrosion treatment: zinc phosphate pretreatment (12-14μm), electrophoretic primer (18-22μm), and black polyester powder coating (70-80μm), passing 1200-hour neutral salt spray tests without red rust. This protection ensures durability in coastal (saltwater), snowy (road salt), or industrial (chemical debris) environments, with a service life of over 8 years—outperforming plastic or low-grade aluminum nets

Unlike solid under-bumper guards that block airflow, the 8406038-C6100 protective net is engineered to preserve the GX’s under-hood cooling system performance. Its open mesh structure (78% air permeability) allows unobstructed airflow to the radiator and intercooler, ensuring under-hood temperatures remain within optimal ranges (≤95°C for engine coolant) during heavy loads or high-speed driving. Computational fluid dynamics (CFD) testing confirms the net causes only a 2% reduction in airflow compared to an uncovered bumper—far below the 15% reduction of solid guards. This design prevents engine overheating, a critical advantage for long-haul trucks operating in hot climates or hauling heavy cargo

Exclusively tailored for Dongfeng GX heavy-duty trucks (including cargo, long-haul, and dump variants), the 8406038-C6100 protective net strictly adheres to original equipment (OE) specifications. Manufactured using 3D laser scanning of the GX’s under-bumper area and CNC bending for the frame, it achieves dimensional accuracy within ±0.2mm—matching every curve and mounting point of the bumper’s lower edge. The net includes 8 pre-drilled mounting holes (M8 threaded, 12mm 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 2021, including those with bumper-mounted tow hooks or fog lights (featuring precision cutouts for these components), requiring no drilling or modification

The 8406038-C6100 protective net is designed for hassle-free installation and minimal upkeep, ideal for truck fleets. It comes with a complete hardware kit: 8 grade 8.8 high-strength bolts, lock nuts, washers, and rubber gaskets (to prevent frame-bumper scratches). The lightweight design (4.2kg) and clear mounting marks allow two technicians to install it in 30-35 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 brush to remove mud, gravel, or debris—no special tools required. The powder-coated frame resists scratches and stains, maintaining appearance with minimal effort, while the galvanized mesh avoids rust-related maintenance issues
