Dongfeng VL truck parts Left front pillar guard assembly 5402009-C0150

Built to withstand frequent impacts from road debris (e.g., stones, gravel) and minor collisions (e.g., loading dock contact), the pillar guard is crafted from a PP+15% glass fiber composite. This material delivers a flexural strength of 78 MPa and impact resistance of 9 kJ/m² (notched Izod at 23°C), resisting cracking or deformation from repeated stress. The composite’s heat resistance (continuous use temperature up to 105°C) prevents warping even when exposed to direct sunlight or engine bay heat. Unlike thin plastic guards that peel or break easily, this reinforced composite maintains structural integrity for over 150,000 km of use—matching the VL’s cab service life. It also resists chemical damage from road salt, diesel fuel, and car wash detergents, retaining its appearance without discoloration

Engineered to shield the left front pillar (a critical structural component) from damage, the guard features a reinforced upper edge (3mm-thick composite) that absorbs impact energy from flying debris—reducing pillar dents by 60% compared to unprotected pillars. The lower edge includes a 15mm-tall rubber buffer strip (EPDM material) that cushions contact with loading equipment or curbs, preventing scratches or cracks on the guard and pillar. A raised rib structure (5mm tall) runs vertically along the guard’s center, enhancing its torsional stiffness by 35% and preventing bending under pressure. Unlike flat guards that offer minimal protection, this design ensures the VL’s left front pillar stays intact in harsh working environments (e.g., construction sites, mining operations)

Designed to endure outdoor elements, the pillar guard undergoes a dual-protection treatment. The outer surface is coated with a UV-stabilized acrylic finish (20μm thickness) that blocks 99% of UVA/UVB rays, preventing fading or brittleness—even after 3,000 hours of direct sunlight exposure. The inner surface features a self-adhesive foam tape (1.5mm thick, acrylic-based) that seals gaps between the guard and pillar, blocking dust, rainwater, and wind noise from entering the cab. Testing confirms the guard resists water intrusion during 500mm/h rain simulations, and the foam tape retains adhesion in temperatures ranging from -40°C to 85°C. This weather resistance ensures the guard remains functional and the cab interior stays clean/dry in all climates

Designed for quick, hassle-free replacement (no professional tools needed), the guard uses a clip-on design with 12 integrated nylon clips (grade PA66 for flexibility) that snap into the VL’s pillar clip holes. Installation takes 15–20 minutes: clean the pillar surface with isopropyl alcohol to remove grease/dust, align the guard’s clips with the pillar holes, press firmly until the clips “click” into place, and verify no movement. The clips’ tensile strength (≥180N) ensures the guard stays secure even during high-speed driving or vibration (e.g., unpaved roads). For added stability, the guard’s top and bottom ends include small screws (included in the kit) that fasten to the windshield frame and door sill, preventing edge lifting. Each unit undergoes clip retention testing, dimensional inspection, and impact checks, backed by a 12-month warranty against defects (e.g., clip breakage, coating peeling, composite cracking)
