Dongfeng KR truck parts Wind deflector 1309011-KS1A1 in stocked

Designed with computational fluid dynamics (CFD) simulation, the deflector optimizes airflow over the truck’s cab and trailer (if equipped), reducing aerodynamic drag by 12–15%. Its curved leading edge redirects oncoming wind upward and away from the cab’s rear, minimizing turbulent airflow that increases fuel consumption. In real-world testing, this aerodynamic improvement translates to a 3–5% reduction in fuel usage for long-haul trips—critical for fleet operators aiming to lower operational costs. Unlike flat or poorly shaped deflectors that may increase drag, this design aligns with Dongfeng KR’s overall aerodynamic profile, ensuring maximum efficiency at highway speeds (60–100km/h)

Crafted from glass-fiber-reinforced polypropylene (PP-GF20), the deflector balances rigidity and flexibility to withstand harsh trucking conditions. The composite material resists impact from road debris (e.g., stones, branches) without cracking, enduring 1kg weight drops from 0.8m with only minor surface damage. It also tolerates extreme temperatures: -40°C (freezing winters) to 90°C (hot summers) without warping or brittleness. The surface is infused with UV stabilizers that pass 2,000 hours of xenon arc testing (simulating 6 years of sun exposure) to prevent fading or discoloration. Unlike metal deflectors that rust or low-grade plastic ones that split, this material ensures the deflector maintains structural integrity for 7+ years

Beyond aerodynamic benefits, the deflector serves as a protective barrier for the cab and rear components. It blocks 85% of wind-driven rain, snow, and road salt from hitting the cab’s rear window and side mirrors—reducing visibility issues during inclement weather and minimizing corrosion on body panels. The deflector also redirects small debris (e.g., gravel, dust) away from the cab’s roof vents and antenna, preventing clogging or damage. For trucks with trailers, it reduces airflow between the cab and trailer, lowering the risk of trailer sway in crosswinds. Unlike basic deflectors that only address wind resistance, this design offers comprehensive protection for daily and long-haul operations

Engineered for easy replacement by fleet technicians or DIY owners, the deflector simplifies installation and upkeep. It includes all necessary hardware: 8 M8×30mm stainless steel bolts, lock washers, and rubber gaskets that fit directly into the truck’s pre-drilled mounting holes. No specialized tools are needed—installation takes 30–40 minutes by aligning the deflector with the cab’s reference marks, tightening the bolts to 35 N·m torque, and securing the gaskets to prevent water intrusion. For maintenance, the smooth composite surface cleans easily with a pressure washer (up to 110 bar) or damp cloth, and no repainting is required. The material is resistant to oil, coolant, and road chemicals, so spills won’t stain or degrade it. Each unit undergoes dimensional checks (via CMM), impact testing, and aerodynamic verification, backed by a 24-month warranty against defects (e.g., cracking, fading, mounting hole misalignment)
