Dongfeng KR truck parts Bumper Upper Grille 8406035-C5100

Built to withstand road debris, minor collisions, and extreme weather, the grille uses high-performance PP (polypropylene) plastic with 20% glass fiber reinforcement. This material combination delivers a tensile strength of 35 MPa and impact resistance of 20 kJ/m², enabling it to endure hits from stones or branches at highway speeds without cracking. The grille’s honeycomb mesh structure (8mm×8mm cell size) balances rigidity and flexibility—absorbing minor impacts to prevent bumper damage while maintaining structural integrity. Unlike brittle ABS grilles that shatter on impact, this PP composite design tolerates temperature extremes from -40°C to 85°C (resisting warping in summer heat or freezing winters) and retains its shape for 5+ years of heavy use

Engineered to optimize airflow to the radiator and reduce wind resistance, the grille features a streamlined honeycomb pattern with angled cells (15° from vertical) that direct air toward the engine bay while minimizing turbulence. Computational fluid dynamics (CFD) testing shows it improves cooling airflow by 12% compared to damaged or ill-fitting grilles, helping maintain optimal engine temperatures during heavy loads or high ambient temperatures. The outer frame’s curved edges also reduce drag by smoothing airflow around the bumper corners, contributing to a 2% improvement in fuel efficiency for long-haul driving. Unlike blocked or poorly designed grilles that restrict cooling or increase drag, this aerodynamic layout supports both engine performance and fuel economy

Designed to resist fading, discoloration, and chemical damage, the grille undergoes a multi-step surface treatment process. It features a UV-stabilized black matte finish (RAL 9005) that withstands 2,000 hours of xenon arc testing (equivalent to 6 years of sun exposure) without fading. The surface is also treated with an anti-static coating that repels dust and debris, reducing the need for frequent cleaning. When cleaning is needed, the smooth plastic surface wipes clean with a damp cloth—resisting stains from road salt, bug splatters, or industrial chemicals. Unlike painted grilles that chip or peel, this durable finish maintains a uniform appearance, ensuring the truck’s front end looks professional even after years of use

Designed for hassle-free replacement by fleet technicians or DIY owners, the grille simplifies installation with user-friendly features. It includes 8 pre-attached nylon mounting clips (PA66 grade) that align with the bumper’s original slots—installation takes 10–15 minutes: remove the old grille by gently prying the clips, clean the bumper cavity, align the new grille’s clips with the slots, and press firmly until all clips engage (audible “clicks” confirm secure fit). The grille is fully compatible with Dongfeng KR’s original front bumper accessories, including the center logo badge, license plate bracket, and front-facing cameras (if equipped)—no adapter parts required. Each unit undergoes fitment testing, impact trials, and UV resistance checks, backed by a 24-month warranty against defects (e.g., cracking, clip failure, finish fading)
