Dongfeng xinjiang truck parts Right bend bracket assembly 8403070-C42KE04Y

Built to withstand the mechanical stress of truck operation—including static loads (up to 500kg) and dynamic torsion from road vibrations—this bracket assembly features a reinforced Q355B low-alloy high-strength steel structure. The main body (8mm thick) delivers a minimum yield strength of 355MPa and tensile strength of 470-630MPa, ensuring it resists bending or deformation even under heavy loads (e.g., supporting exhaust systems or fuel tanks). The 90° bend joint is reinforced with 12mm-thick triangular gussets, which distribute torsional forces evenly and prevent cracking at the stress concentration point. Unlike thin carbon steel brackets, Q355B’s low-temperature toughness (-40℃ impact energy ≥34J) avoids brittle fracture in freezing environments, critical for trucks operating in cold regions. This robust design ensures the bracket maintains structural integrity for over 8 years of heavy-haul use

Engineered to resist corrosion from road salt, mud, rain, and chassis grease—major threats to undercarriage components—the bracket assembly 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 (80-100μm) with epoxy-polyester composite is baked on, forming a scratch-resistant, waterproof barrier that resists peeling even after prolonged exposure to chemicals or 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 10 years in coastal areas, rainy regions, or winter roads with deicing salt. All mounting holes are coated with anti-seize compound, preventing thread rust and enabling easy removal during maintenance

Designed for precise component mounting, the bracket assembly undergoes CNC cutting, bending, and drilling to achieve strict dimensional accuracy. The 90° bend angle has a tolerance of ±0.5°, ensuring the bracket aligns perfectly with the mounted component (e.g., exhaust pipe or fuel line) and avoids forced installation that could damage seals or connections. Mounting holes are drilled with a concentricity error of ≤0.1mm, guaranteeing perfect alignment with the chassis frame’s pre-drilled holes and preventing bolt cross-threading. The bracket’s surface roughness is ≤1.6μm, ensuring flat contact with the mounting surface and even load distribution. Additionally, the bracket’s edges are deburred and rounded (radius: 2mm) to prevent damage to adjacent hoses or wires during installation or operation. This precision ensures the mounted component functions as intended, reducing wear and extending its service life

Beyond its primary use, the right bend bracket assembly supports versatile applications across Dongfeng Xinjiang trucks—serving as a mounting solution for exhaust systems, fuel lines, air tanks, or cab support structures. The package includes 6 galvanized M10×35 high-strength bolts (grade 10.9), lock washers, and flat washers that match the factory thread specifications. Installation steps are straightforward: align the bracket’s holes with the chassis/body mounting points, secure with the included bolts, and torque to the recommended 45-50N·m with a standard wrench. No specialized tools are required, and one technician can complete installation in 30 minutes or less. The bracket’s design also allows for future adjustments (e.g., repositioning of mounted components) via its multiple mounting holes, enhancing flexibility for maintenance or modifications. This versatility and easy installation reduce labor costs and minimize truck downtime for commercial operators
