Dongfeng VR truck parts Right front outer panel 5301662-C1100

Built to withstand minor collisions, road debris impacts, and daily wear (critical for front-facing cab panels), the outer panel uses 1.5mm-thick cold-rolled DC03 steel with a minimum yield strength of 170 MPa. The material undergoes precision stamping to replicate the VR’s original curved contours, with reinforced edges (2mm thickness) at high-impact areas (e.g., headlight cavity perimeter, lower bumper contact zone) to absorb and distribute impact force. Finite Element Analysis (FEA) testing confirms it can withstand a 5kg weight impact at 2m/s (simulating a small rock strike) without permanent deformation, and maintains structural integrity under 100,000+ cycles of vibration (equivalent to 5 years of road use). Unlike thin aluminum or plastic panels that dent or crack easily, this high-strength steel design ensures long-term durability and protects the cab’s internal components from external damage

Designed to resist corrosion from rain, road salt, mud, and UV exposure (common in front-end environments), the panel undergoes a comprehensive four-stage anti-corrosion treatment. First, a zinc phosphate conversion coating (60μm thickness) creates a porous base to enhance coating adhesion. Next, an electrophoretic primer (80μm) is applied to form a uniform moisture barrier, followed by a high-build polyester primer (50μm) that fills minor surface imperfections. Finally, a UV-stabilized polyester topcoat (40μm, matching the VR’s original cab color options: white, red, or blue) is baked on to resist chipping, fading, and chemical damage from diesel or road deicers. This coating system passes 1,200 hours of neutral salt spray testing (equivalent to 10 years of road salt exposure) without rust or peeling, ensuring the panel retains its appearance and structural integrity in harsh weather conditions

Engineered to integrate seamlessly with the Dongfeng VR’s front-end components, the panel features built-in design elements that enhance functionality and sealing. A 10mm-wide flange along the door edge includes a pre-installed EPDM rubber seal that creates a watertight and windproof barrier between the outer panel and right front door, reducing cabin noise by 15%. The headlight cavity includes a recessed groove (5mm depth) for the headlight’s rubber gasket, ensuring a tight seal that prevents water from entering the headlight housing. Pre-punched holes (8mm diameter) at the top and bottom edges accommodate the VR’s front grille mounting clips, eliminating the need for on-site drilling. Unlike generic panels that require additional sealing or adapter parts, this integrated design simplifies installation and ensures all front-end components work together seamlessly

Designed for hassle-free replacement by body shops or fleet technicians, the panel simplifies installation with precision-machined features and user-friendly design. All mounting holes are drilled to H9 tolerance (ensuring perfect alignment with the VR’s front frame bolts) and deburred to avoid damaging bolt threads or adjacent panels. Four laser-etched alignment marks on the panel’s inner surface line up with reference points on the VR’s cab frame, eliminating guesswork and reducing installation time by 40% (typically 30–40 minutes). The package includes all necessary hardware: 12 M6×16mm self-tapping bolts, 8 plastic push clips for grille attachment, and a roll of butyl sealant for additional water protection. Installation steps are straightforward: clean the cab frame mounting surface, align the panel’s marks with the frame, secure the bolts and clips, and apply the butyl sealant along the door and headlight edges. Each unit undergoes dimensional verification via CMM, coating adhesion testing, and impact resistance checks, backed by a 24-month warranty against defects (e.g., rust, coating peeling, dimensional inaccuracies)
