Dongfeng VR truck parts Upper right wheel cover 8403432-C1100

Built to shield the right wheel well, brake components, and chassis from road debris (stones, mud, salt) and minor impacts, the wheel cover uses a dual-material structure. The core layer is 3mm-thick glass-fiber reinforced plastic (GFRP) with a tensile strength of 320 MPa, providing rigidity to resist deformation from flying stones. The outer layer is 1mm-thick thermoplastic elastomer (TPE) with high impact resistance—passing -35°C low-temperature impact testing without cracking, even when struck by 500g debris at 60km/h. Reinforced ribs (8mm height) are molded along the inner edge at 150mm intervals, distributing impact force across the chassis and preventing localized damage to the wheel well. Unlike thin plastic covers that crack or break easily, this composite design endures 120,000+ km of rough road use while protecting critical underbody components from premature wear

Designed to resist corrosion from road salt, mud, rain, and UV exposure (common in wheel well environments), the wheel cover undergoes comprehensive protective treatment. The GFRP core is coated with a marine-grade epoxy primer (70μm thickness) that seals fiber pores and blocks moisture intrusion. The TPE outer layer is infused with UV-stabilizers and anti-aging additives, maintaining flexibility and color stability for 8+ years—resisting fading even after 3,000 hours of direct sunlight exposure. All metal mounting hardware (M8 bolts, washers) are made of 304 stainless steel, resisting rust and ensuring long-term attachment strength. The cover’s inner surface features a 2mm-thick foam gasket that creates a moisture barrier between the cover and chassis, preventing water from seeping into the wheel well and causing brake component rust. Unlike unprotected covers that degrade quickly, this design ensures durability in snowy, coastal, or off-road conditions

Engineered to reduce wind resistance and enhance the truck’s visual coherence, the wheel cover features an aerodynamic curved design. The outer surface is shaped to streamline airflow around the wheel well, reducing drag by 8% (per wind tunnel testing) and improving fuel efficiency by approximately 2% for long-haul operations. The cover’s color is pre-matched to Dongfeng VR’s factory cab colors (white, red, blue), with a matte finish that resists scratches and hides minor road grime—maintaining the truck’s professional appearance. A 15mm-wide recessed edge along the top and bottom aligns with the cab’s side panel, creating a seamless transition that eliminates wind noise (reducing cabin noise by 5% at highway speeds). Unlike boxy or ill-fitting covers that increase drag, this optimized design balances functionality with fuel savings and aesthetics

Designed for hassle-free replacement by fleet technicians or DIY owners, the wheel cover simplifies installation with a user-friendly attachment system. It includes 6 pre-installed plastic push clips (that snap into the VR’s wheel well pre-drilled holes) and 4 M8×30mm stainless steel bolts for additional securement at high-stress areas (e.g., near the tire’s top travel path). Two laser-etched alignment marks on the cover’s inner surface line up with reference points on the chassis, ensuring precise positioning in 20–25 minutes—no specialized tools needed, only a socket wrench for the bolts. The cover’s lower edge features a flexible TPE flap that overlaps the tire’s sidewall (without contact) to block debris, while drainage slots (10mm width) at the bottom channel rainwater and mud away from the wheel well. Each unit undergoes fitment testing, impact resistance checks, and aerodynamic verification, backed by a 30-month warranty against defects (e.g., clip breakage, material cracking, color fading)
