Dongfeng Xinjiang X7 truck parts Left bumper assembly 8406021-TXGG01Y

Built to absorb impact energy and protect critical front-end components (e.g., radiator, engine oil pan) from collisions, the bumper features a hybrid structure. The outer shell uses high-grade PP (polypropylene) plastic reinforced with 25% glass fiber (impact resistance: 28 kJ/m²) to withstand minor impacts (e.g., curb scrapes, small debris hits) without cracking. The internal reinforcement beam is 3mm-thick Q345B steel (tensile strength: 470–630 MPa) that absorbs major impact forces, meeting ECE R42 collision safety standards. The steel beam is welded to 4 aluminum alloy mounting brackets (lightweight yet rigid) that distribute stress across the chassis, preventing localized deformation. Unlike all-plastic bumpers that shatter in high-impact scenarios, this hybrid design balances durability and weight, ensuring protection for 8+ years of heavy use

Engineered to optimize airflow along the front of the truck, the bumper features a streamlined curved profile with integrated air curtains (120mm-wide channels along the lower edge). Computational Fluid Dynamics (CFD) testing shows it reduces aerodynamic drag by 12% compared to aftermarket bumpers, translating to a 2–3% improvement in fuel efficiency (equivalent to ~400L of diesel saved annually for a truck driving 100,000km/year). The lower lip is angled 5° upward to redirect airflow away from the front tires, minimizing turbulence and road noise at highway speeds (60–100km/h). Unlike boxy, non-aerodynamic bumpers that increase fuel consumption, this design supports both cost savings and environmental efficiency for fleet operators

Designed to enhance practicality, the bumper integrates dedicated provisions for key front-end components. It includes a pre-molded fog lamp cavity (180mm×120mm) that fits the X7’s original fog lamps (no adapter brackets needed), ensuring proper light alignment for low-visibility conditions. A hidden tow hook cover (located on the lower right section) provides easy access to the tow hook—simply flip open the cover (no tools required) when emergency towing is needed. The bumper also has 4 pre-drilled holes for front license plate mounting (matching the X7’s license plate bracket), eliminating the need for self-drilling. Unlike basic bumpers that lack component compatibility, this integrated design simplifies accessory installation and maintains the truck’s functional integrity

Engineered to resist corrosion from road salt, rain, and UV radiation, the bumper undergoes a multi-stage protective treatment. The steel reinforcement beam receives hot-dip galvanization (zinc coating thickness ≥90μm) + electrophoretic primer (70μm), while the plastic shell is coated with a UV-stabilized polyester topcoat (50μm, matching the X7’s original paint color). This coating system passes 1,200 hours of neutral salt spray testing (equivalent to 10 years of road salt exposure) without rust or fading. For installation, the bumper includes 8 pre-attached alignment pins that fit the chassis’s guide holes, reducing installation time by 40% (typically 40–50 minutes). It comes with all hardware: 8 M10 bolts, lock washers, and foam gaskets for vibration damping. Each unit undergoes impact testing, dimensional verification via CMM, and coating adhesion checks, backed by a 36-month warranty against defects (e.g., cracking, rusting, coating peeling)
