Dongfeng KL truck part Lower bumper grille 8406036-C3300

Beyond aesthetics, the grille serves two critical functional roles: protecting under-bumper components and ensuring efficient cooling. Its rigid structure acts as a barrier against road debris (e.g., gravel, branches) and minor impacts (e.g., hitting curbs), shielding the radiator, intercooler, and fog light wiring from damage—reducing repair costs by 50% compared to unprotected bumpers. The grille features 8mm-wide vertical slots that cover 75% of the bumper opening, providing optimal airflow to the radiator (supporting up to 600 CFM air volume) and ensuring the engine maintains a safe operating temperature (82–95°C) even in high-temperature environments. Unlike solid bumper inserts that block airflow and cause overheating, this design balances protection with ventilation, making it suitable for both highway hauling and off-road construction use

Built to withstand harsh outdoor conditions—including UV radiation, road salt, and temperature fluctuations—the grille uses premium, heavy-duty materials. The base is crafted from glass-fiber-reinforced PP (polypropylene) with 20% GF content, which resists cracking in low temperatures (-40°C) and warping in high heat (85°C) while enduring impacts from small debris (1kg weight drop from 0.5m without damage). The surface is coated with a UV-resistant acrylic layer (60μm thickness) that prevents fading or discoloration, passing 2,000 hours of xenon arc testing (simulating 5 years of sun exposure) with no visible degradation. The grille’s edges are reinforced with a 3mm-thick PP trim that resists chipping from accidental contact, ensuring long-term structural integrity. Unlike low-grade plastic grilles that become brittle within 1–2 years, this design lasts 5+ years in harsh trucking environments

Designed to enhance the Dongfeng KL’s front-end appearance, the grille features a factory-matched matte black finish that complements the truck’s bumper and upper grille, creating a cohesive, professional look. Its vertical slot design aligns with the truck’s upper grille pattern, maintaining visual symmetry and reinforcing the Dongfeng KL’s brand identity. The grille also includes pre-cut openings for fog lights (if equipped), ensuring seamless integration with the bumper’s existing lighting system—unlike generic grilles that require modifying fog light mounts. For fleet operators, this consistent aesthetic helps maintain a uniform brand image, while individual owners benefit from a grille that preserves the truck’s original factory look and resale value

Engineered for hassle-free replacement by fleet technicians or DIY owners, the grille simplifies installation and upkeep. It requires no specialized tools—just align the grille with the bumper’s mounting tabs, press firmly to secure the clips, and fasten the 6 included plastic fasteners (hand-tightened, no wrench needed). Installation takes 15–20 minutes, even for first-time users. For maintenance, the grille can be easily removed (by prying the clips with a plastic trim tool) for deep cleaning (pressure washable up to 80 bar) to clear trapped dirt or road salt. The matte black finish resists stains from oil or mud, wiping clean with a damp cloth. Each unit undergoes strict quality checks: dimensional verification via CMM (Coordinate Measuring Machine), impact testing, and weather resistance trials. Backed by a 18-month warranty against manufacturing defects (e.g., cracking, fading, clip failure), it provides Dongfeng KL truck owners with a reliable, low-maintenance front-end component
