Dongfeng xinjiang X7 truck parts bumper Primary step bracket assembly 8406220-TXGG01Y

Built to safely support personnel accessing the X7’s front end (e.g., checking the engine, cleaning the windshield), this bracket assembly delivers robust load-bearing performance. It is fabricated from Q235 carbon steel (6mm thick for the step platform, 8mm thick for support arms) with a tensile strength of ≥375MPa, enabling it to handle a maximum static load of 300kg (equivalent to two adult users) without deformation. The step platform features a reinforced crossbeam (10mm thick) running its full length, which distributes weight evenly across the chassis and prevents bending. Unlike lightweight aluminum brackets, this steel structure resists permanent deformation even under repeated heavy use—critical for the X7’s commercial applications (e.g., construction site workers, fleet maintenance staff). In durability tests, the bracket maintains its shape and load capacity after 10,000+ use cycles, ensuring long-term safety

Designed with user safety as a priority, the bracket assembly incorporates anti-slip and structural safety features. The step platform’s surface is punched with a diamond-pattern texture (hole diameter: 5mm, spacing: 15mm) that provides strong friction—even when wet or covered in mud—preventing foot slippage. Raised edge lips (15mm tall) around the platform’s perimeter block tools or debris from falling off during use, reducing ground hazards. The support arms are angled at 15° to the vertical, creating a stable triangular structure that resists lateral forces (e.g., a user leaning against the bumper). Additionally, all sharp edges are rounded (radius: 3mm) to prevent cuts or scrapes during access, complying with Dongfeng Xinjiang’s safety standards for external vehicle components

Engineered to withstand the harsh conditions of the truck’s front end—including road salt, rain, mud, and stone chips—the bracket assembly 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 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 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 assembly undergoes CNC cutting and drilling to achieve strict dimensional accuracy (length/width tolerance: ±0.5mm, hole position tolerance: ±0.1mm). The package includes 6 M10×25 bolts (for bumper connection) and 4 M12×35 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 M12 bolts (torque to 50-55N·m), then attach the bumper to the bracket using M10 bolts (torque to 30-35N·m). No specialized tools are required, and a professional technician can complete the process in 40 minutes or less. The bracket’s design also includes alignment marks (engraved “TOP” and “LEFT/RIGHT” indicators) to prevent incorrect installation, ensuring the step platform is level and safely positioned on the first attempt. This easy installation reduces labor costs and minimizes truck downtime for commercial operators
