Dongfeng Xinjiang X7 truck parts Right bumper assembly 8406022-TXGG01Y

Built to protect critical front-end components (e.g., radiator, oil cooler, right front axle) from collisions, the bumper features a durable hybrid structure. The outer shell is made of 25% glass fiber-reinforced PP (polypropylene) plastic, delivering an impact resistance of 28 kJ/m² to withstand minor impacts (e.g., curb scrapes, stone hits) without cracking. The internal reinforcement beam is 3mm-thick Q345B structural steel (tensile strength: 470–630 MPa) that absorbs major impact energy, meeting ECE R42 collision safety standards. Four aluminum alloy mounting brackets (lightweight yet rigid) connect the steel beam to the chassis, distributing stress evenly to prevent localized deformation. Unlike all-plastic bumpers that shatter in high-impact scenarios, this hybrid design balances durability and weight, ensuring reliable protection for 8+ years of heavy use

Engineered to optimize airflow along the truck’s front right side, the bumper features a streamlined curved profile with integrated air curtains (120mm-wide channels along the lower edge). Computational Fluid Dynamics (CFD) testing confirms 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 right front tire, minimizing turbulence and road noise at highway speeds (60–100km/h). Unlike boxy, non-aerodynamic bumpers that increase fuel consumption, this design supports cost savings for fleet operators while reducing environmental impact

Designed to enhance practicality, the bumper integrates dedicated provisions for essential front-end components. It includes a pre-molded fog lamp cavity (180mm×120mm) that perfectly fits the X7’s original right fog lamp—no adapter brackets required—ensuring proper light alignment for low-visibility conditions (rain, fog, dust). A hidden tow hook cover (located on the lower right section) provides tool-free access to the tow hook: simply flip open the cover to expose the hook when emergency towing is needed. The bumper also has pre-drilled holes for right-side auxiliary lights (if equipped), eliminating the need for self-drilling that risks damaging the bumper structure. Unlike basic bumpers with limited functionality, this integrated design simplifies accessory installation and maintains the truck’s operational integrity

Engineered to resist corrosion from road salt, rain, and UV radiation, the bumper undergoes a comprehensive multi-stage protective treatment. The steel reinforcement beam receives hot-dip galvanization (zinc coating thickness ≥90μm) followed by an electrophoretic primer (70μm) for maximum rust resistance. The plastic shell is coated with a UV-stabilized polyester topcoat (50μm, matching the X7’s original paint color) that resists fading and chalking. This coating system passes 1,200 hours of neutral salt spray testing (equivalent to 10 years of road salt exposure) without degradation. 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). All hardware (8 M10 bolts, lock washers, foam vibration gaskets) is included. 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)
