Dongfeng GX Vertical mudguard 8403349-C6103 in stocked

Constructed from high-density polyethylene (HDPE) with a thickness of 5mm, the 8403349-C6103 vertical mudguard offers exceptional durability and resistance to harsh environmental factors. HDPE exhibits excellent impact strength (notched Izod impact strength of 8 kJ/m² at -30°C), enabling it to withstand collisions with rocks or curbs without cracking or breaking. The material is also UV-resistant, with a built-in anti-aging additive that prevents brittleness and color fading—passing 1500-hour xenon lamp aging tests with no significant loss of flexibility or structural integrity. Furthermore, HDPE is chemically resistant to road salts, diesel, and cleaning agents, ensuring the mudguard remains intact even after prolonged exposure to corrosive substances. This robust construction guarantees a service life of over 6 years, far exceeding the lifespan of standard rubber or low-grade plastic mudguards

Exclusively designed for Dongfeng GX commercial vehicles (including heavy-duty trucks and cargo models), this vertical mudguard strictly adheres to the original equipment (OE) specifications of part number 8403349-C6103. It is manufactured using 3D injection molding with CNC precision tooling, achieving dimensional accuracy within ±0.3mm—seamlessly fitting the Dongfeng GX’s rear wheel arch, frame brackets, and axle components. The mudguard features 6 pre-drilled mounting holes (M8 threaded, 10mm depth) and 2 locating tabs that align perfectly with the vehicle’s existing mounting points, eliminating gaps that could allow debris to pass through. It is fully compatible with all Dongfeng GX models produced since 2021, making it a direct replacement part for factory assembly or after-sales repairs—no trimming, drilling, or modification is required, saving technicians valuable installation time

The 8403349-C6103 vertical mudguard is engineered for hassle-free installation and minimal maintenance. It comes with a complete hardware kit, including 6 stainless steel bolts, lock washers, and rubber gaskets—eliminating the need for separate part sourcing. The mudguard’s lightweight design (only 1.2kg) reduces handling effort, and the clearly marked mounting holes allow for quick alignment (installation can be completed in 20-25 minutes by a single technician, 30% faster than non-OE mudguards). For maintenance, the smooth HDPE surface is easy to clean: mud or debris can be hosed off with water, and stubborn stains can be wiped away with a damp cloth—no special cleaning agents are required. The material’s non-stick properties also prevent mud from adhering to the surface, reducing the need for frequent cleaning

Beyond protection, the 8403349-C6103 mudguard contributes to a quieter, more efficient driving experience for the Dongfeng GX. Its streamlined, curved design reduces aerodynamic drag by minimizing air turbulence around the rear wheels, which translates to a 2-3% improvement in fuel efficiency (based on 100km road tests at highway speeds). The mudguard also acts as a noise barrier, absorbing and dampening the sound of gravel and debris hitting the vehicle’s chassis—reducing road noise in the cabin by 5-8 dB, especially at high speeds. Additionally, the rubber gaskets included in the hardware kit create a tight seal between the mudguard and vehicle frame, preventing wind noise from entering the cabin and further enhancing driving comfort during long-haul trips
