Dongfeng VL Air Deflector 1309012-K0101 with original quality

Developed through computational fluid dynamics (CFD) simulations and real-road wind tunnel testing, this air deflector features a streamlined curved profile that optimizes airflow around the Dongfeng VL cab. By redirecting oncoming air upward and away from the cab’s front and roof, it effectively minimizes aerodynamic drag—typically reducing wind resistance by 9-13% during highway driving (varies by truck load and speed). This drag reduction directly translates to tangible fuel efficiency improvements: fleet operators and truck owners can expect to save 4-6% on fuel costs annually (based on an average annual mileage of 120,000 km and standard diesel consumption). Additionally, the deflector suppresses turbulent airflow behind the cab, lowering wind noise inside the driver’s compartment by 3-5 dB—enhancing driving comfort during long-haul trips

The deflector’s main body is constructed from automotive-grade modified PP (Polypropylene) composite material infused with UV stabilizers, impact modifiers, and anti-aging additives. This material combination delivers exceptional performance in extreme conditions: it remains structurally stable from -35°C (cold winter climates with frost) to 85°C (hot summer sunlight exposure), without cracking, warping, or discoloration. It also exhibits strong impact resistance—capable of withstanding minor collisions with road debris (e.g., small stones, branches) or accidental bumps during loading/unloading without permanent damage. The surface is treated with a scratch-resistant and anti-fingerprint coating, which maintains a smooth, clean appearance even after prolonged exposure to dust, rain, or road salt—reducing the need for frequent cleaning or touch-ups

To ensure reliability under heavy-duty use, the air deflector incorporates multiple structural enhancements. The mounting brackets are made of hot-dip galvanized steel (with a 8-10μm zinc coating) that provides superior corrosion resistance—preventing rust even in high-humidity environments (e.g., coastal areas or frequent rain) and extending bracket service life to 6+ years. The deflector’s edge is reinforced with a 2mm-thick rubber seal, which not only buffers vibration between the deflector and cab roof (reducing wear and noise) but also forms a tight barrier against water, dust, or debris infiltration. Additionally, the deflector’s internal rib structure (3 longitudinal ribs and 2 cross ribs) enhances overall rigidity, ensuring it does not deform or flex under strong winds (e.g., highway speeds of 90-100 km/h or gusty weather conditions)

Designed for user-friendly maintenance, this air deflector comes with a complete installation kit—including galvanized bolts, lock washers, rubber gaskets, and a step-by-step instruction manual (with diagrams). It leverages the Dongfeng VR’s original roof mounting points, allowing for tool-free alignment and straightforward installation: most users can complete the process in 25-40 minutes using only basic hand tools (e.g., a socket wrench and screwdriver). The lock washers feature a non-slip design that prevents bolt loosening caused by road vibrations or long-term use, ensuring the deflector remains securely fastened even on rough terrain (e.g., unpaved roads or construction sites). For added convenience, the installation manual includes clear labeling of mounting points and torque specifications (typically 25-30 N·m for bolts), reducing the risk of installation errors for both professional mechanics and individual truck owners
