Dongfeng xinjiang truck parts protective support of the frame 2809218-T5KF04Y

Built to protect the truck’s frame rails and underlying components from road hazards, this support delivers comprehensive defensive performance. The outer surface features a 10mm-thick steel impact plate that absorbs and disperses force from rocks, curbs, or debris—preventing dents or cracks in the frame’s high-stress areas (e.g., cross-member joints). A 5mm-thick rubber buffer pad (EPDM material) lines the inner side of the support, creating a shock-absorbing barrier between the support and frame—reducing vibration-induced wear (by 40% compared to unbuffered supports) and noise. Additionally, the support extends 120mm below the frame rail, acting as a “skid plate” to deflect obstacles away from vulnerable components like fuel lines or wiring harnesses. This multi-layer protection extends the frame’s service life by 30% and minimizes costly chassis repairs

Engineered to endure the mechanical stress of truck operation—including static loads (up to 800kg) and dynamic torsion from uneven roads—the protective support 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 cargo loads (e.g., full-load hauling on construction sites). The support’s connection points to the frame are reinforced with 12mm-thick triangular gussets, which distribute torsional forces evenly and prevent cracking at stress concentrations. Unlike thin carbon steel supports, 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 support maintains structural integrity for over 8 years of heavy-duty use

Designed to resist corrosion from road salt, mud, rain, and chassis grease—major threats to undercarriage components—the protective support 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 efficient installation on Dongfeng Xinjiang trucks, the protective support undergoes CNC cutting, bending, and drilling to achieve strict dimensional accuracy. The 6 mounting holes are drilled with a concentricity error of ≤0.1mm, ensuring perfect alignment with the frame rail’s pre-drilled holes and preventing bolt cross-threading. The support’s surface roughness is ≤1.6μm, ensuring flat contact with the frame and even load distribution. The package includes 6 galvanized M12×40 high-strength bolts (grade 10.9), lock washers, and flat washers that match the factory thread specifications. Installation steps are straightforward: align the support with the frame rail, secure with bolts (torque to 60-65N·m), and verify clearance with adjacent components. No specialized tools are required, and one technician can complete installation in 40 minutes or less. This easy installation design reduces labor costs and minimizes truck downtime—critical for commercial operators relying on continuous vehicle availability
