Dongfeng VL truck parts front Suspension Cover Plate 2901105-T38A0

As a key protective component for the front suspension, this cover plate effectively shields core mechanical parts from road hazards. The 7mm-thick full-coverage structure protects leaf springs, bushings, kingpins, and mounting bolts from gravel impact, mud accumulation, and water erosion—reducing abrasive wear by 60% compared to uncovered suspensions. In harsh working conditions like construction sites or muddy rural roads, it blocks large debris from jamming the suspension travel, lowering the risk of sudden steering failure by 45%. The arc-shaped design redirects water and dust downward, preventing rust on metal components and extending the front suspension’s maintenance interval by 35%

Engineered for the extreme stresses of heavy-duty transportation, the cover plate is made of Q355B high-strength structural steel, boasting a tensile strength of 530-660MPa and yield strength of ≥355MPa—30% stronger than conventional Q235 steel. It undergoes hot forming and stress-relief annealing to eliminate internal defects, ensuring no deformation even when the truck bears its maximum front axle load (12 tons). Reinforced folded edges (10mm thickness) and integrated mounting bosses enhance structural rigidity, while the plate’s surface is shot-blasted to achieve a uniform stress distribution. Finite element testing confirms it can withstand 45g impact loads from road obstacles, far exceeding daily operation requirements

The cover plate features a professional anti-corrosion system to adapt to diverse operating environments of Dongfeng VL trucks. It undergoes three treatment processes: zinc phosphating for rust prevention, cathodic electrophoretic coating (75μm thickness) for base protection, and polyester powder coating (55μm thickness) for wear resistance. This combination passes 1800-hour neutral salt spray testing (ASTM B117) with zero red rust, making it suitable for coastal high-salt areas. The coating also resists UV aging and chemical corrosion from road de-icing agents, maintaining performance in temperatures ranging from -45℃ (frigid northern winters) to 90℃ (hot southern summers). No additional anti-corrosion maintenance is needed during its service life

Designed for efficient fleet maintenance, the front suspension cover plate offers convenient installation and long-term cost savings. It comes with 10 pre-configured M14×40 high-tensile bolts and lock washers, which precisely match the original mounting holes on the suspension beam. Installation requires only a torque wrench (180-200N·m) and can be completed by two technicians in 35 minutes—50% faster than non-OE plates that require drilling. Weighing just 15kg, the plate is easy to handle during installation. With a service life of over 300,000km, it reduces front suspension repair costs by 40% by preventing component damage, making it a cost-effective choice for fleet managers and truck owners
