Body system
This right spoiler (Part No. 8407018-C4320) is exclusively designed for the front panel of Dongfeng KC heavy-duty trucks (including KC385, KC420, and KC460 models). Its contour (length: 480mm, height: 220mm, curvature radius: 35mm) perfectly matches the original front panel’s right-side edge, with 4 pre-drilled mounting holes (diameter: 8mm) aligning 100% with the front panel’s threaded seats. It adheres to Dongfeng’s original design specifications, ensuring no gaps or misalignment when installed—seamlessly integrating with the truck’s front-end appearance

PRODUCT DESCRIPTION
Aerodynamic Optimization for Fuel Efficiency
Engineered with a streamlined arc structure, the spoiler effectively redirects airflow along the front panel’s right side during driving. It reduces air resistance by minimizing turbulent airflow around the front wheel well, lowering the truck’s aerodynamic drag coefficient by approximately 3-5% (tested under standard highway driving conditions: 60-90km/h). This optimization helps improve fuel efficiency by 1.2-1.5L/100km for long-haul transportation, reducing overall operating costs
Durable Material & Weather-Resistant Performance
Base Material: Made of high-impact PP (polypropylene) composite material with 15% glass fiber reinforcement, featuring a tensile strength of ≥35MPa and impact strength (notched Izod) of ≥8kJ/m². It can withstand accidental collisions with small road debris without cracking or permanent deformation.
Surface Treatment: Coated with a two-layer finish—electrostatic primer (thickness: 20μm) and high-gloss automotive-grade topcoat (thickness: 40μm)—matching the original front panel’s color (Dongfeng standard metallic silver/red). The coating resists UV aging (passing 1,000-hour xenon lamp test with no color fading) and chemical corrosion from road salt, engine oil, and cleaning agents
Easy Installation & Tool-Free Adjustment
The spoiler adopts a bolt-on installation design, compatible with the original front panel’s existing mounting hardware (4 M6×16 stainless steel bolts included in the package). No drilling or cutting of the front panel is required—professional technicians can complete installation in 15-20 minutes using a standard socket wrench. Additionally, the spoiler’s edge is equipped with a flexible EPDM rubber gasket, which automatically adjusts to minor front panel surface irregularities, ensuring a tight seal and preventing wind noise during driving
Protective Function for Front-End Components
Beyond aerodynamic benefits, the spoiler acts as a protective barrier for the front panel’s right-side edge and adjacent components (such as the right front turn signal and fog lamp). It blocks road splashes (mud, water, gravel) from directly hitting the front panel’s lower edge, reducing scratches, rust, and paint chipping. The raised outer edge (height: 15mm) also prevents small objects from getting stuck between the front panel and the right front wheel, minimizing potential damage to the front-end structure
TECHNICAL SUPPORT
1. Accessories selection consultation
- Provide ** intelligent selection tools ** (such as parts matching query system), input the vehicle model VIN code or engine model to match the corresponding parts number, reducing the selection error rate.
The technical team is available online 7×12 hours to answer technical questions about accessories (such as material compatibility and installation processes).
2. Customized development support
We offer specialized R&D services for special market demands (such as heat dissipation accessories for high-temperature regions in the Middle East and dedicated suspension components for road conditions in Africa), and complete sample delivery within six weeks.
3. Training and Technical materials
Provide remote/on-site training for the customer's after-sales team (such as diagnosis of electrical control accessories and DPF regeneration operation), along with multilingual versions of the "Accessories Installation Manual" and "Troubleshooting Guide".
4. Quality Traceability and Improvement
Through the QR code traceability system (one product, one code), track the production batch of accessories and the source of raw materials, respond quickly to quality complaints and initiate improvement processes.
AFTER-SALES AND LOGISTICS SUPPORT

Quality Assurance Policy
-The warranty period for original factory parts is 12 months (counting from the date of signature for receipt), covering material defects, process issues, and man-made damage.
- Provide "Localized Express repair Service" : Cooperate with third-party repair networks in markets such as Southeast Asia and the Middle East, and deliver emergency parts to designated repair points within 4 hours.
Return and Exchange Process
-The customer is required to submit the test report (such as a third-party appraisal) within the warranty period. After confirmation by Dongfeng, a reissue or refund will be arranged within 5 working days.
Logistics support
Warehouse Layout
-Five major regional accessory centers have been established globally (Southeast Asia, the Middle East, Africa, South America, and Europe) to achieve "next-day delivery" for mainstream accessories (covering customers within the regions).
Emergency Logistics Plan
-Emergency parts can be directly delivered within 48 hours via the "Dongfeng Exclusive Aviation Special Line" (such as engine ECU, brake valves and other key components).
Packaging Optimization
-Use shockproof and moisture-proof packaging (such as honeycomb cartons + pearl cotton), and reinforce fragile parts (such as glass, sensors), keeping the damage rate within 0.5%.
