Dongfeng Xinjiang X7 truck parts Left bracket in the middle of the bumper 8406217-TXGG01Y

Built to secure the X7’s front bumper and absorb minor impact forces, this bracket delivers robust load-bearing performance. It is fabricated from Q235 carbon steel (5mm thick) with a tensile strength of ≥375MPa, enabling it to support the bumper’s weight (up to 35kg) plus withstand frontal impacts of up to 500N (equivalent to a low-speed collision with a curb). The bracket’s structure includes a vertical reinforcement rib (8mm thick) running the length of the body, which distributes impact force to the chassis and prevents bending. Unlike plastic brackets (common in passenger cars), this steel bracket resists deformation even under repeated stress—critical for the X7’s heavy-duty use (e.g., construction site driving, off-road hauling). In tests, the bracket maintains its shape and mounting position after 100+ minor impact cycles, ensuring the bumper remains securely attached

Designed to eliminate bumper vibration during driving, the bracket features a rigid, low-deflection structure that locks the bumper in place. The chassis mounting points are spaced 180mm apart to create a stable base, while the bumper attachment holes are precision-drilled to ensure a tight fit with the bumper’s mounting studs. The bracket’s contact surface with the bumper is flat (surface roughness ≤1.6μm) and lined with a 1mm-thick EPDM rubber pad, which absorbs road vibrations (5-2000Hz, compliant with ISO 16750-3) and prevents metal-to-metal contact that could cause rattling. This design reduces bumper movement by 90% compared to loose-fitting brackets, eliminating annoying vibration noise and preventing premature wear of the bumper’s plastic components

Engineered to withstand the harsh conditions of the truck’s front end—including road salt, rain, mud, and stone chips—the bracket features a comprehensive anti-corrosion system. First, a zinc phosphate pretreatment layer (10μm) is applied to the steel surface to block rust at the substrate. Then, a high-temperature electrostatic powder coating (90μm) with epoxy-polyester composite is baked on, forming a scratch-resistant, waterproof barrier that resists peeling even after exposure to UV radiation. Finally, a clear chromate passivation layer enhances coating adhesion and chemical resistance. This system passes 1200-hour salt spray testing (per ASTM B117) with no red rust, ensuring durability for over 8 years in coastal areas or winter roads with deicing salt. All mounting holes are coated with anti-seize compound, preventing thread rust and enabling easy removal during bumper repairs

Designed for efficient installation on the Dongfeng Xinjiang X7, the bracket undergoes CNC cutting and drilling to achieve strict dimensional accuracy (length/width tolerance: ±0.5mm, hole position tolerance: ±0.1mm). The package includes 4 M8×20 bolts (for bumper connection) and 3 M10×30 bolts (for chassis attachment)—all galvanized and grade 8.8 for high strength. Installation steps are straightforward: align the bracket’s chassis holes with the X7’s front frame pre-drilled points, secure with M10 bolts (torque to 45-50N·m), then attach the bumper to the bracket using M8 bolts (torque to 25-30N·m). No specialized tools are required, and a professional technician can complete the process in 30 minutes or less. The bracket’s design also includes alignment marks (engraved “TOP” and “LEFT” indicators) to prevent incorrect installation, ensuring the bumper is positioned correctly on the first attempt. This easy installation reduces labor costs and minimizes truck downtime for commercial operators
