Dongfeng VL truck parts White right front outer side panel 5301660-C4301

Built to withstand minor front-end impacts (e.g., road debris, low-speed collisions) and long-term structural stability, the panel is crafted from 0.8mm-thick cold-rolled steel (CR4 grade). This material delivers a minimum tensile strength of 340 MPa and yield strength of 210 MPa, enabling it to resist deformation under a static load of 1,200 N (equivalent to the force of a 10kg object striking at 5km/h). The steel undergoes a full hardening process (HRC 28–32) to enhance surface hardness, reducing scratch damage from gravel or tools. Compared to thin-gauge aluminum panels, this cold-rolled steel design offers 40% higher impact resistance while maintaining lightweight properties—critical for balancing protection and fuel efficiency

The panel features a factory-matched white paint finish (Pantone 11-4102 TPX, Dongfeng VL’s standard white color) applied via an automated electrocoating process—ensuring no color deviation from the original vehicle. The coating system includes four layers: a zinc phosphate conversion layer (60μm) for corrosion resistance, an electrophoretic primer (80μm) for adhesion, a high-build epoxy mid-coat (70μm) for smoothness, and a polyurethane topcoat (50μm) for gloss and durability. The topcoat delivers a 90% gloss rating (measured via 60° gloss meter) and resists fading under UV exposure (tested to 3,000 hours of xenon lamp aging with ≤3% color change). Unlike spray-painted aftermarket panels, this factory coating eliminates the need for repainting, reducing repair time by 70% for body damage

Engineered to enhance front-body rigidity and prevent warping, the panel integrates 5mm-thick reinforcing ribs along the edge of the headlight cutout and bottom mounting area. These ribs increase the panel’s torsional stiffness by 35%, reducing vibration-induced fatigue cracks during long-haul driving (e.g., highway transport with frequent road bumps). A 15mm-deep recess at the door interface ensures tight fitting with the right front door seal, maintaining the cab’s interior waterproofing and sound insulation. The panel’s lower edge also includes a drainage slot (10mm wide) to channel rainwater away from the front frame, preventing corrosion at the mounting points. These structural details extend the panel’s service life by 50% compared to non-reinforced designs

Designed for efficient replacement by body shops or fleet technicians, the panel comes with a complete hardware kit and tool-free alignment features. It includes 18 stainless steel M6×16mm bolts (grade 304, rust-resistant), 20 plastic push-in clips (matching the VL’s factory clip size), and a tube of automotive-grade sealant for the door interface. The panel’s pre-drilled mounting holes (drilled to H9 tolerance) align perfectly with the VL’s front frame threaded holes, reducing installation time to 60–90 minutes. No welding or custom fabrication is needed—simply remove the damaged panel, align the new panel using the factory reference marks, secure with bolts and clips, and apply sealant to the edges. Each unit undergoes dimensional inspection via CMM, paint adhesion testing (cross-cut test grade 5B), and impact resistance checks, backed by a 18-month warranty against defects (e.g., paint peeling, steel warping, clip breakage)
