Dongfeng Xinjiang truck parts Rear right mudguard bracket assembly 8511085-T5KECG01

Built to securely hold the rear right mudguard (weight: 5-8kg) during truck operation, this bracket assembly features a reinforced Q355B high-strength steel structure. The main support arm (5mm thick) delivers a minimum yield strength of 355MPa and tensile strength of 470-630MPa, enabling it to withstand road vibrations, wind resistance, and minor impacts (e.g., from flying debris) without bending or deformation. Key stress points (e.g., bracket-to-chassis joints, mudguard mounting plates) are reinforced with 4mm-thick triangular gussets, which distribute weight evenly and prevent cracking at high-stress areas. Unlike thin carbon steel brackets, Q355B’s low-temperature toughness (-40℃ impact energy ≥34J) avoids brittle fracture in freezing winter conditions—critical for trucks operating in cold regions. This robust strength ensures the mudguard remains stable even on bumpy roads or during heavy-haul transportation (25+ tons), preventing mudguard sagging or detachment

Engineered to resist corrosion from mud, rain, road salt, and water splashes—major threats to rear chassis parts—the bracket assembly 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 even after prolonged exposure to muddy water. 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, rainy regions, or winter roads with deicing salt. All threaded holes are coated with anti-seize compound, preventing thread rust and enabling easy bolt removal during mudguard replacement or chassis maintenance

Designed for efficient installation, the bracket assembly 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 rear chassis and mudguard. The package includes 6 galvanized M10×35 bolts, lock washers, and rubber gaskets (for vibration damping and water sealing) that match the factory thread specifications. Installation steps are straightforward: align the bracket’s holes with the rear chassis mounting points, secure the bolts to the recommended torque (32N·m) with a standard wrench, then attach the mudguard to the bracket using the factory’s existing fasteners. One technician can complete installation in 25 minutes or less, avoiding time-consuming on-site adjustments. For repair shops or truck operators, this easy installation design reduces labor costs and minimizes rear-end downtime—critical for commercial trucks relying on daily transportation

Beyond fixing the mudguard, the bracket assembly is designed to enhance the mudguard’s functionality and longevity. It features a built-in vibration-damping structure: rubber gaskets between the bracket and mudguard absorb road vibrations, preventing metal-to-metal contact that could cause mudguard cracking or noise. The bracket’s outward tilt angle (12°) is calibrated to position the mudguard optimally—ensuring it effectively blocks mud, water, and stones from splashing onto the rear tires, brake system, or adjacent vehicles. Additionally, the bracket’s edges are rounded and deburred (radius: 2mm), preventing scratches on the mudguard or damage to nearby components (e.g., brake hoses) during installation or operation. The assembly also includes pre-installed cable clips to organize rear light wiring, avoiding wire wear from mudguard vibration. This focus on functional enhancement ensures the mudguard and rear-end components remain protected and operational for longer, reducing maintenance costs for Dongfeng Xinjiang truck owners
