Dongfeng VL Air Deflector 1309012-T45H0 in stocked

Developed through wind tunnel testing and aerodynamic simulation, this air deflector features a streamlined curved contour that optimizes airflow around the truck’s cab. By redirecting oncoming air upward and away from the truck’s front and roof, it effectively reduces aerodynamic drag—typically cutting wind resistance by 8-12% during highway driving (varies by truck configuration). This reduction directly translates to improved fuel efficiency, helping fleet operators and truck owners save 3-5% on fuel costs annually (based on average annual mileage of 100,000 km). Additionally, the deflector minimizes turbulent airflow behind the cab, reducing wind noise inside the driver’s compartment for a quieter driving experience

Constructed from automotive-grade modified PP (Polypropylene) composite material with added UV stabilizers and impact-resistant additives, this air deflector exhibits exceptional durability. It can withstand extreme temperature fluctuations—remaining stable in performance from -30°C (cold winter conditions) to 80°C (hot summer sunlight) without cracking, warping, or discoloration. The material also boasts strong impact resistance, capable of withstanding minor collisions with debris (e.g., small stones, branches) during road travel without permanent damage. Furthermore, the surface is treated with a scratch-resistant coating, which maintains the deflector’s smooth appearance and prevents unsightly marks from regular use or cleaning

To ensure long-term reliability under heavy use, the air deflector incorporates multiple structural enhancements. The mounting brackets are made of galvanized steel (with a corrosion-resistant zinc coating) that prevents rusting even in humid or rainy environments, extending the bracket’s service life to 5+ years. The deflector’s edge is reinforced with a thickened rubber seal, which not only buffers vibration between the deflector and the truck’s cab (reducing noise and wear) but also prevents water from seeping into the cab roof. Additionally, the internal rib structure of the deflector enhances its overall rigidity, ensuring it does not deform under strong winds (e.g., during high-speed driving or in stormy weather)

Designed for user-friendly maintenance, this air deflector comes with a complete installation kit (including galvanized bolts, lock washers, and rubber gaskets) and is compatible with the Dongfeng VL’s original mounting points. The installation process requires no specialized tools—most users can complete it in 30-45 minutes with basic hand tools (e.g., a wrench, screwdriver). The deflector is fixed using high-torque bolts and lock washers, which prevent loosening caused by road vibrations or strong winds. Moreover, the installation manual (included in the kit) provides step-by-step instructions with diagrams, making it easy for both professional mechanics and individual truck owners to install correctly. After installation, the deflector maintains a secure fit even during long-distance transportation or off-road driving
