Dongfeng Xinjiang truck parts Left connection bracket 8406161-TXGG01Y

Built to withstand the vibrations, impacts, and component weight of truck operation, this left connection bracket features a reinforced Q355B high-strength steel structure. The main support plate (4.8mm thick) delivers a minimum yield strength of 355MPa and tensile strength of 470-630MPa, enabling it to securely support the left headlight (3-4.5kg) and absorb road vibrations without bending or deformation. Key stress points (e.g., hole peripheries, bracket-to-component joints) are reinforced with 3mm-thick triangular gussets, which distribute pressure evenly and prevent cracking at high-stress areas. Unlike ordinary carbon steel brackets, Q355B’s low-temperature toughness (-40℃ impact energy ≥34J) avoids brittle fracture in freezing winter conditions. This robust strength ensures the bracket maintains component stability during long-haul driving, off-road operations, or minor front-end scrapes, preventing costly damage to headlights or bumpers

Engineered to resist corrosion from road salt, rain, mud, and humidity—major threats to front-end truck parts—the bracket features a professional three-layer anti-corrosion system. First, a zinc phosphate pretreatment layer (8μm) is applied to the steel surface to block rust at the substrate. Then, a high-temperature electrostatic powder coating (70-90μm) with epoxy-polyester composite is baked on, forming a scratch-resistant, waterproof barrier that resists peeling or fading. Finally, a clear chromate passivation layer enhances coating adhesion and chemical resistance. This system passes 1000-hour salt spray testing (per ASTM B117) with no red rust, ensuring the bracket remains corrosion-free for over 7 years in coastal areas or winter roads with deicing salt. All threaded holes are coated with anti-seize compound, preventing thread rust and enabling easy bolt removal during maintenance or component replacement

Designed for efficient installation, the left connection bracket undergoes CNC machining to achieve strict dimensional accuracy and surface quality. Its length/width tolerance is controlled within ±0.5mm, and the pre-drilled holes have a concentricity error of ≤0.1mm—ensuring perfect alignment with the truck’s mounting bolts and front-end components. The package includes 6 galvanized M10×30 bolts, lock washers, and flat washers that match the factory thread specifications. Installation steps are straightforward: align the bracket’s holes with the front frame and left headlight/bumper mounting points, insert the bolts through the washers, and tighten to the recommended torque (28N·m) with a standard wrench. One technician can complete installation in 18 minutes or less, avoiding time-consuming on-site adjustments. For repair shops or truck operators, this easy installation design reduces labor costs and minimizes front-end downtime—critical for commercial trucks relying on daily transportation tasks

Beyond connecting the left headlight and bumper, the bracket is designed to support multiple front-end functions in Dongfeng Xinjiang trucks. It serves as: 1) A fog light mounting base—with pre-marked holes for securing the left fog light (if equipped), ensuring optimal low-visibility illumination angle (15° downward tilt) to avoid glare for oncoming vehicles; 2) A wiring harness organizer—featuring built-in plastic clips to route headlight/fog light wiring, preventing wire wear from vibration or contact with sharp components; 3) A minor impact buffer—its reinforced structure absorbs small impacts from road debris (e.g., stones, gravel) to protect the left headlight lens and bumper cover from cracks. The bracket’s compact design avoids interference with the truck’s front tires, steering components, or airflow, ensuring no impact on driving performance or aerodynamics. This versatility makes the bracket a multi-purpose spare part, reducing inventory costs for repair facilities and ensuring truck owners have a reliable solution for various front-end maintenance needs
