Dongfeng Xinjiang X7 truck parts bumper Middle right bracket 8406218-TXGG01Y

Built to secure the X7’s front bumper and absorb lateral/vertical forces, this bracket delivers robust load-bearing performance. It is fabricated from Q235 carbon steel (5mm thick for the main body, 7mm thick for stress ribs) with a tensile strength of ≥375MPa, enabling it to support the bumper’s weight (up to 32kg) plus withstand frontal impact forces of up to 450N (equivalent to low-speed contact with curbs or debris). The bracket’s structure includes two vertical reinforcement ribs (running the full height of the body) and one horizontal cross-rib, which distribute impact energy to the chassis and prevent bending or cracking. Unlike plastic alternatives (common in light vehicles), this steel bracket maintains structural integrity even under repeated stress—critical for the X7’s heavy-duty use in construction, logistics, or off-road scenarios. In durability tests, the bracket retains its shape and mounting position after 80+ minor impact cycles

Designed to eliminate bumper vibration during driving, the bracket features a precision-engineered structure that locks the bumper in place. The contact surface between the bracket and 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 causes annoying rattling noises. The chassis mounting holes are spaced 170mm apart to create a stable triangular base, while the bumper attachment holes are drilled with a concentricity error of ≤0.2mm—ensuring a tight fit with the bumper’s mounting studs. This design reduces bumper movement by 85% compared to loose-fitting brackets, protecting the bumper’s plastic components from premature wear and maintaining a quiet cab environment for drivers

Engineered to resist corrosion from road salt, rain, mud, and stone chips (common in the truck’s front end), the bracket features a professional three-layer 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 (85μm) with epoxy-polyester composite is baked on—forming a scratch-resistant, waterproof barrier that resists peeling even after prolonged exposure to UV radiation or road chemicals. 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, snowy regions, or industrial zones with high pollution. All mounting holes are pre-coated with anti-seize compound, preventing thread rust and enabling easy removal during bumper maintenance

Designed for efficient installation on the Dongfeng Xinjiang X7, the bracket undergoes CNC cutting, drilling, and bending to achieve strict dimensional accuracy (length/width tolerance: ±0.5mm, hole position tolerance: ±0.1mm). The package includes 4 M8×20 galvanized bolts (for bumper connection) and 3 M10×30 grade 8.8 high-strength bolts (for chassis attachment)—matching the X7’s factory hardware specifications. 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 25 minutes or less. The bracket also includes engraved alignment marks (“TOP” and “RIGHT”) to prevent incorrect installation, ensuring the bumper is positioned correctly on the first attempt—reducing labor costs and minimizing truck downtime for fleet operators
