Dongfeng GX truck parts Right rear wheel mudguard assembly 8511140-HA410

Designed to shield the Dongfeng GX’s rear-end components from road debris, the assembly features a dual-layered protection structure. The main mudguard panel (600mm in height) extends 150mm below the rear wheel’s centerline, blocking 90% of mud, water, and gravel kicked up by the tire—preventing damage to the rear bumper, tailpipe, wiring harnesses, and adjacent vehicles. A secondary rubber flap (attached to the mudguard’s lower edge) adds 80mm of extra coverage, conforming to road irregularities to catch fine debris that might slip past the main panel. The mudguard’s curved design redirects debris downward and outward, reducing splashing on the truck’s body (which causes corrosion) and minimizing visibility issues for following vehicles—critical for safe driving in rainy or muddy conditions

Built to withstand the harsh demands of commercial truck operation (impact from rocks, temperature extremes, and UV exposure), the mudguard assembly uses high-performance materials. The main panel is crafted from glass fiber-reinforced polyethylene (PE-GF15), a lightweight yet rugged composite that resists cracking, warping, and impact damage—even when hit by large gravel at highway speeds. This material is 50% lighter than steel mudguards (reducing unsprung weight for better fuel efficiency) and immune to rust from road salt or water. The rubber flap is made of wear-resistant EPDM rubber that maintains flexibility in temperatures ranging from -40°C to 120°C, avoiding brittleness in cold weather or melting in hot conditions. Together, these materials ensure the assembly lasts over 8 years of heavy use, reducing replacement frequency

Crafted to match Dongfeng GX’s factory rear-end aesthetics, the mudguard assembly features an OEM-matched black textured finish (or color-matched option, per truck specification) that blends seamlessly with the truck’s rear body panels. The finish resists fading from UV rays and hides minor scratches, preserving the truck’s professional appearance for fleet operators. Functionally, the mudguard includes pre-machined slots for Dongfeng GX’s original rear reflectors (if applicable), ensuring compliance with road safety regulations (e.g., FMVSS 108, ECE R38) that require visible rear reflectors. The assembly also maintains the truck’s original aerodynamic profile—wind tunnel testing confirms it adds less than 1% drag, avoiding negative impacts on fuel efficiency compared to bulky aftermarket mudguards

Engineered for efficient replacement in repair shops or fleet yards, the assembly simplifies installation with user-friendly features. It comes with pre-attached mounting brackets that align with the truck’s factory chassis holes, and includes all necessary hardware (stainless steel bolts, lock washers, and rubber gaskets) to prevent water intrusion at mounting points. Installation takes 30–45 minutes using standard hand tools, with no welding or drilling required. To ensure safety, the assembly undergoes strict testing: impact tests to verify debris-blocking effectiveness, corrosion tests to confirm material durability, and fitment tests to ensure no interference with wheel or suspension movement. It also includes a 24-month warranty against manufacturing defects (e.g., panel cracking, rubber flap tearing, or finish peeling), providing Dongfeng GX truck owners with reliable protection and long-term peace of mind
