Dongfeng GX truck parts Upper mudguard assembly 8511015-H0100

Unlike single-piece mudguards, the 8511015-H0100 is a fully integrated assembly that combines the mudguard shell, internal reinforcing ribs, and pre-attached mounting brackets—eliminating the need for separate part alignment and reducing installation time by 50%. The internal ribs (spaced 60mm apart, 3mm thick) are welded to the mudguard shell via precision robotic welding, creating a rigid framework that resists bending or warping under heavy debris impact (e.g., large rocks or clumps of mud). The pre-attached mounting brackets are also angled to match the GX’s chassis contour, ensuring the assembly sits flush against the truck’s body and avoids vibration-induced noise during driving— a common issue with loosely fitted split mudguards

The assembly features a dual-material design that balances flexibility and strength: the mudguard shell is crafted from high-density polyethylene (HDPE)—a rugged, impact-resistant plastic that absorbs minor impacts without cracking—while the mounting brackets are made from 4mm-thick high-strength steel (Q235 grade) for secure chassis attachment. The HDPE shell resists extreme temperatures, remaining functional at -40°C (cold winter conditions) and 85°C (hot road surfaces), and passes 2000-hour UV aging tests with no brittleness or color fading. The steel brackets undergo a zinc-plating treatment for corrosion resistance, ensuring they remain sturdy even in saltwater or snowy environments. This composite construction makes the assembly 30% lighter than all-steel alternatives while maintaining comparable durability

Exclusively tailored for Dongfeng GX heavy-duty trucks (compatible with 2021+ cargo, dump, and tractor variants), the 8511015-H0100 assembly adheres strictly to original equipment (OE) specifications. Manufactured using 3D laser scanning of the GX’s upper wheel well and chassis, it achieves dimensional accuracy within ±0.3mm—matching every contour of the wheel hub, fender, and chassis brackets. The assembly includes 8 pre-drilled mounting holes that align perfectly with the GX’s factory-installed chassis points, eliminating gaps that could allow debris to seep through. It requires no trimming, bending, or modification to the vehicle’s original structure, ensuring a seamless fit that preserves the truck’s factory integrity and avoids aftermarket-related alignment issues

The 8511015-H0100 assembly is designed for efficient installation and minimal upkeep, ideal for fleet maintenance teams. It comes with a complete OE-spec hardware kit: 8 grade 8.8 stainless steel bolts (M8×30), 8 lock nuts with anti-loosening washers, and 8 rubber gaskets (to prevent metal-to-plastic friction and vibration). Installation requires only standard hand tools (13mm socket wrench) and can be completed by two technicians in 30-35 minutes: align the assembly with the chassis brackets using the pre-drilled holes, secure the bolts to 38±3 N·m (per Dongfeng’s torque specifications), and verify that the mudguard clears the wheel by at least 25mm (to avoid contact during rotation). For maintenance, the HDPE shell wipes clean with a damp cloth or pressure washer—no harsh chemicals needed—and the rubber gaskets can be easily replaced if worn, ensuring long-term vibration resistance
