Dongfeng GX Upper right inner mudguard assembly 8403320-C6100

Constructed from a high-density polyethylene (HDPE) and ethylene-vinyl acetate (EVA) blend (ratio 85:15), the 8403320-C6100 mudguard balances rigidity for protection and flexibility for contour fitting. With a thickness of 5.5mm, the material exhibits excellent impact strength (notched Izod impact strength of 8.8 kJ/m² at -30°C), resisting cracking from flying gravel, while its flexibility (elongation at break: 300%) allows it to conform tightly to the vehicle’s inner upper right contours—eliminating gaps that trap debris. The blend is also UV-stabilized, passing 1600-hour xenon lamp aging tests with no brittleness or color fading, and chemically resistant to road salts and brake fluid—ensuring durability in harsh under-vehicle environments for over 7 years

Exclusively tailored for Dongfeng GX commercial vehicles (including heavy-duty trucks and cargo models), the 8403320-C6100 inner mudguard strictly adheres to original equipment (OE) specifications. Manufactured using 3D scanning of the GX’s inner upper right wheel well and injection molding with CNC tooling, it achieves dimensional accuracy within ±0.2mm—matching every curve and mounting point of the vehicle’s inner frame. The assembly includes 7 pre-drilled mounting holes (M7 threaded, 10mm depth) and 3 snap-fit tabs that align perfectly with the GX’s factory inner brackets, ensuring a gap-free fit that prevents debris infiltration. It is fully compatible with all Dongfeng GX models produced since 2021, including those with lifted suspensions or oversized tires, making it a direct replacement for factory assembly or after-sales repairs

Beyond protection, the 8403320-C6100 inner mudguard contributes to a quieter, cleaner cabin environment. Its dense HDPE-EVA blend absorbs and dampens the sound of debris hitting the inner frame, reducing cabin noise by 6-9 dB (measured at 60-90 km/h) compared to unguarded vehicles. The mudguard also acts as a dust seal, blocking fine particles from entering the cabin through the wheel well and door seal interface—reducing interior dust accumulation by 70%. Additionally, the assembly includes a foam gasket along its upper edge, which creates a tight seal against the vehicle’s inner body panel, preventing wind noise from seeping into the cabin and further enhancing comfort during long-haul trips

The 8403320-C6100 inner mudguard is designed for hassle-free installation and minimal upkeep. It comes with a complete hardware kit, including 7 stainless steel bolts, lock washers, foam gaskets, and snap-fit clips—no additional parts are needed. The lightweight design (1.4kg) and clear laser-engraved mounting marks allow a single technician to install it in 25-35 minutes, accessing the inner upper right wheel well via standard vehicle service points (no disassembly of major components required). For maintenance, the smooth material surface can be cleaned with a pressure washer or damp cloth to remove mud and debris, and the UV-stabilized blend requires no periodic treatments—reducing long-term service costs. The assembly also includes a 24-month warranty against material defects (e.g., cracking, warping) and manufacturing errors
