Dongfeng GX truck parts left rear wheel mudguard assembly 8511130-H11A0

Designed to shield the Dongfeng GX’s rear-end from road hazards, the assembly features a multi-layered protection design. The main mudguard panel extends 160mm below the wheel’s centerline, blocking 92% of mud, water, and gravel kicked up by the tire—preventing scratches, corrosion, or clogging of the rear bumper, tailpipe, brake lines, and wiring harnesses. A flexible rubber flap (90mm in length) is attached to the panel’s lower edge, conforming to uneven road surfaces to catch fine debris that might slip past the main panel. The mudguard’s curved contour redirects debris outward and downward, reducing splashing on the truck’s body (which causes rust) and improving visibility for following vehicles—critical for safe driving in rainy, snowy, or muddy conditions

Built to withstand the harsh conditions of commercial truck operation (impact from rocks, extreme temperatures, and UV exposure), the mudguard assembly uses high-performance materials. The main panel is crafted from glass fiber-reinforced polypropylene (PP-GF15), a lightweight yet rugged composite that resists cracking, warping, and impact damage—even when struck by large gravel at highway speeds (up to 90km/h). This material is 45% lighter than steel mudguards, reducing unsprung weight to improve fuel efficiency by 1–2%. The rubber flap is made of wear-resistant EPDM rubber that maintains flexibility in temperatures ranging from -40°C (cold winters) to 120°C (engine radiant heat), avoiding brittleness or melting. Together, these materials ensure the assembly lasts over 8 years of heavy use, minimizing replacement costs for fleet operators

Crafted to match Dongfeng GX’s factory rear-end design, the mudguard assembly features an OEM-matched black textured finish that blends seamlessly with the truck’s body panels. The finish resists fading from UV rays and hides minor scratches, preserving the truck’s professional appearance—critical for maintaining resale value. Functionally, the mudguard includes pre-cut slots for Dongfeng GX’s original rear reflectors (if equipped), ensuring compliance with international safety regulations (e.g., FMVSS 108 in the U.S., ECE R38 in the EU) that require visible rear reflectors for nighttime visibility. 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 alternatives

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 (no welding or drilling required), even for technicians with limited experience. To guarantee quality, each unit undergoes strict testing: impact tests to verify debris-blocking effectiveness, 800-hour salt spray tests to confirm corrosion resistance, and fitment tests to ensure no wheel/suspension interference. Backed by a 24-month warranty against manufacturing defects (e.g., panel cracking, rubber flap tearing, or finish peeling), the assembly provides Dongfeng GX truck owners with reliable protection and long-term peace of mind
