Dongfeng GX truck parts Upper spoiler right bracket 8407144-C6200

Unlike basic flat brackets, the 8407144-C6200 features an integrated, triangular structural design that combines a vertical support arm, horizontal mounting base, and diagonal reinforcement rib—distributing stress evenly across the bracket and eliminating weak points. The vertical support arm (5mm-thick high-strength steel, Q355B grade) and diagonal rib (4mm-thick) are robotically welded at a 45° angle, enhancing the bracket’s load-bearing capacity to 200N (e.g., spoiler weight plus wind pressure during high-speed driving)—far exceeding the 120N capacity of generic brackets. The horizontal mounting base (6mm-thick) also has a 70mm-wide contact area with the truck’s upper front chassis, ensuring stable attachment and preventing bracket tilting or bending under pressure

The bracket’s core components are crafted from Q355B high-strength steel—selected for its exceptional tensile strength (≥510 MPa) and impact resistance—ensuring durability in harsh under-hood and front-end environments. To combat corrosion (a common failure point for front-end brackets exposed to rain, road salt, and humidity), all steel parts undergo a four-step anti-corrosion process: first, a zinc phosphate pretreatment (15-17μm thick) creates a porous adhesion base; second, an electrophoretic primer (22-25μm thick) forms a moisture barrier; third, an epoxy mid-coat (18-20μm thick) adds chemical resistance; finally, a matte-black polyester powder coating (85-95μm thick) provides scratch protection. This treatment passes 1500-hour neutral salt spray tests with no red rust formation, making the bracket suitable for trucks operating in coastal (saltwater spray) or snowy (de-icing salts) regions

Exclusively tailored for 2022+ Dongfeng GX heavy-duty trucks (cargo, long-haul, and dump variants), the 8407144-C6200 adheres strictly to original equipment (OE) specifications. Manufactured using 3D laser scanning of the GX’s upper front chassis and upper right spoiler mounting points, it achieves dimensional accuracy within ±0.15mm—matching every chassis mounting hole, spoiler bolt position, and component contour of the factory design. The bracket includes 4 pre-drilled chassis mounting holes (M10 threaded, 18mm depth) that align perfectly with the GX’s upper front reinforcement brackets, eliminating the need for on-site drilling (which weakens chassis integrity). It also features a 12mm offset design that matches the GX’s upper spoiler routing, ensuring no interference with adjacent components (e.g., wiring harnesses, front sensors, or grille)

The 8407144-C6200 is designed for efficient installation and minimal upkeep, ideal for fleet maintenance teams. It comes with a complete OE-spec hardware kit: 4 grade 12.9 high-strength bolts (with anti-loosening nylon washers), 4 lock nuts, 2 rubber gaskets (for spoiler and chassis mounting), and a printed alignment template. Installation requires only standard hand tools (13mm socket wrench) and can be completed by two technicians in 15-20 minutes: align the bracket with the chassis using the template, secure the base to the reinforcement bracket, attach the upper spoiler to the bracket’s mounting plate, and torque bolts to 48±3 N·m (per Dongfeng’s torque specifications). The powder-coated finish and rubber gaskets require no regular maintenance—simply wipe clean with a damp cloth to remove dust or oil—ensuring long-term reliability with minimal effort
