Dongfeng GX truck parts Lower left spoiler 8407135-C6203

Beyond aerodynamics, the 8407135-C6203 spoiler acts as a robust barrier for the truck’s lower-left undercarriage and wheel well components. Its 3mm-thick leading edge deflects road debris (e.g., gravel, rocks, mud) away from sensitive parts like the left front brake lines, fuel lines, and chassis reinforcement rails, reducing scratches, punctures, and corrosion. The spoiler’s extended design (covering 70% of the left wheel well opening) also blocks water and road salt from splashing upward into the wheel well, preventing rust on the wheel hub and suspension components. For trucks operating in construction, mining, or snowy regions, this protection extends the lifespan of undercarriage parts by 25-30%, lowering maintenance costs

Constructed from glass-fiber reinforced polypropylene (PP-GF20)—a high-performance non-metallic material—the 8407135-C6203 spoiler balances lightweight performance and rugged durability. Weighing only 1.4kg (35% lighter than steel alternatives), it reduces the truck’s unsprung mass without compromising strength. The PP-GF20 material exhibits exceptional impact resistance: it can withstand minor collisions with curbs or debris without cracking, thanks to its flexibility that absorbs impact energy. It also resists extreme temperatures—maintaining shape at -30°C (cold climates) and 90°C (engine bay heat)—and passes 1800-hour UV aging tests with no brittleness or color fading. Unlike painted metal, it is impervious to road salt and chemicals, ensuring long-term durability in harsh environments

Exclusively tailored for Dongfeng GX heavy-duty trucks (2022+ cargo, long-haul, and dump variants), the 8407135-C6203 spoiler adheres strictly to original equipment (OE) specifications. Manufactured using 3D laser scanning of the GX’s lower-left front bumper and wheel well, it achieves dimensional accuracy within ±0.2mm—matching every contour, edge, and mounting point of the truck’s factory design. The spoiler includes 5 integrated snap-fit tabs and 3 pre-drilled mounting holes that align perfectly with the GX’s lower bumper reinforcement brackets, eliminating gaps that could trap dirt or cause wind noise. It requires no trimming, grinding, or modification to the vehicle’s original structure, ensuring seamless integration and preserving the truck’s factory-installed integrity

The 8407135-C6203 spoiler is designed for hassle-free installation and minimal upkeep, ideal for fleet maintenance teams. It comes with a complete OE-spec hardware kit: 3 grade 8.8 stainless steel self-tapping screws (M6×14), 5 plastic snap-in fasteners, and a printed alignment guide. Installation requires only basic hand tools (Phillips screwdriver, plastic pry tool) and can be completed by a single technician in 15-20 minutes: align the spoiler with the lower bumper using the guide, secure the snap tabs for initial hold, and fasten the screws to 10±1 N·m (per Dongfeng’s safety specifications). For maintenance, the spoiler’s smooth surface wipes clean with a damp cloth or pressure washer—no harsh chemicals needed—to remove accumulated mud or debris. Its snap-fit design also allows easy removal for undercarriage inspections, ensuring convenient access to wheel well components without damaging the spoiler
