Dongfeng GX truck parts Right longitudinal mudguard 8403350-C6200

Constructed from high-density polyethylene (HDPE) with a thickness of 6.5mm, the 8403350-C6200 mudguard offers exceptional durability and resistance to harsh environmental factors. HDPE exhibits superior impact strength (notched Izod impact strength of 9.5 kJ/m² at -30°C), enabling it to withstand collisions with rocks, curbs, or heavy debris without cracking or breaking—critical for trucks operating in construction zones or unpaved roads. The material is infused with UV-stabilizers to prevent brittleness and color fading, passing 2000-hour xenon lamp aging tests with no loss of flexibility or structural integrity. It is also 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 8 years, far exceeding the lifespan of standard rubber or low-grade plastic mudguards

Exclusively designed for Dongfeng GX heavy-duty trucks (including cargo, long-haul, and dump truck variants), this right longitudinal mudguard strictly adheres to original equipment (OE) specifications of part number 8403350-C6200. It is manufactured using 3D injection molding with CNC precision tooling, achieving dimensional accuracy within ±0.18mm—seamlessly fitting the Dongfeng GX’s right-side frame rails, wheel arch contours, and axle mounting brackets. The mudguard includes 14 pre-drilled mounting holes (M8 threaded, 12mm depth) and 5 locating tabs that align perfectly with the truck’s existing attachment points, eliminating gaps that could allow debris to pass through. It is fully compatible with all Dongfeng GX models produced since 2022, including those with dual rear wheels or lifted suspensions, making it a direct replacement part for factory assembly or after-sales repairs—no trimming, drilling, or modification is required

Beyond protection, the 8403350-C6200 mudguard contributes to a quieter, more fuel-efficient operation for Dongfeng GX trucks. Its streamlined longitudinal design reduces aerodynamic drag by minimizing air turbulence along the truck’s right side, which translates to a 3.5-5.5% improvement in fuel efficiency (based on 100km road tests at highway speeds of 60-90 km/h)—a significant cost-saving for long-haul fleets. The mudguard also acts as a noise barrier, absorbing and dampening the sound of gravel and debris hitting the underbody, reducing cabin noise by 9-12 dB during operation. Additionally, the assembly includes a rubber gasket between the mudguard and frame rails, which creates a tight seal to prevent wind noise from entering the cabin and blocks moisture from seeping into the frame, further enhancing driver comfort and chassis durability

The 8403350-C6200 right longitudinal mudguard is engineered for hassle-free installation and minimal maintenance, ideal for truck fleets needing efficient servicing. It comes with a complete hardware kit, including 14 stainless steel bolts, lock washers, rubber gaskets, and mounting clips—eliminating the need for separate part sourcing. The mudguard’s lightweight design (only 3.5kg) reduces handling effort, and the clearly marked mounting holes allow for quick alignment (installation can be completed in 40-50 minutes by two technicians, 35% 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 and lowering fleet maintenance costs
