Dongfeng KL truck parts Lower and middle protective plates on the left and right side panels 5402025026-C3800

Built as the first line of defense for the Dongfeng KL’s side panels, these protective plates feature a robust design to withstand harsh operational impacts. Constructed from high-strength steel (Q690 grade) with 4mm thickness, they achieve a tensile strength of 690MPa and impact resistance of 25kJ/m²—capable of absorbing 80% of the force from collisions with road debris, gravel, or low-speed impacts. The plates extend 50mm beyond the side panel’s surface, creating a physical barrier that prevents dents or punctures to the cab’s outer skin (repair costs up to $1,200). A corrugated inner structure (wave height 15mm) enhances energy dissipation, while the bottom edge is angled upward to avoid catching on curbs or obstacles during off-road driving

Engineered to resist corrosion and wear in harsh working conditions, the 5402025026-C3800 protective plates adopt a multi-layer advanced coating system. The base layer undergoes hot-dip galvanization (80μm thickness) for superior rust prevention, followed by a cathodic electrophoretic primer (30μm thickness) that ensures uniform coating adhesion. The top layer is a textured powder coating (50μm thickness) with anti-scratch properties (pencil hardness ≥2H), resisting scuffs from rocks and construction materials. This system passes 3000-hour neutral salt spray testing (ASTM B117) with no rust—ideal for coastal regions, snowy areas (road salt exposure), and construction sites with high humidity. The coating also resists diesel fuel and industrial cleaners, maintaining durability with minimal maintenance

Optimized to balance protection and fuel efficiency, the protective plates feature an aerodynamic, lightweight design. The outer surface is streamlined to follow the cab’s contour, reducing wind resistance by 12% compared to bulky aftermarket plates—translating to a 1-2% fuel savings for long-haul fleets (significant over 100,000km annually). Despite their high strength, the use of Q690 high-strength steel reduces each plate’s weight to 8.5kg—20% lighter than standard carbon steel plates—without compromising durability. Strategic cutouts (aligned with the side panel’s drainage holes) prevent water pooling, while the 50mm gap between the plate and side panel promotes air circulation, reducing moisture buildup and corrosion risk

These side panel protective plates are designed for efficient installation and long-term cost savings for Dongfeng KL operators. The pre-assembled mounting hardware (including bolts, washers, and snap clips) allows a two-person team to complete replacement of both left and right plates in 2 hours using only basic hand tools. The OE-compatible design ensures perfect alignment with adjacent trim pieces, avoiding the mismatched gaps common with aftermarket plates that compromise aerodynamics and aesthetics. By protecting the side panels from damage, they reduce repair frequency and extend the cab’s service life by 30%. Backed by a 3-year/300,000km Dongfeng warranty, they provide reliable protection and predictable maintenance expenses, making them a cost-effective investment for fleets
