Dongfeng GX truck parts Upper right bend pipe bracket assembly 8407172-C6100

Unlike basic single-piece brackets, the 8407172-C6100 is an integrated assembly that combines a main support plate, two diagonal reinforcement ribs, and a chassis-mounting base—creating a rigid framework that resists bending or deformation. The main support plate (5mm-thick high-strength steel, Q355B grade) and reinforcement ribs (4mm-thick) are robotically welded at 45° angles, distributing stress evenly across the bracket and eliminating weak points. This structural reinforcement allows the assembly to withstand a static load of 150N (e.g., pipe weight plus fluid pressure) without permanent deformation—far exceeding the 80N load capacity of generic brackets. The chassis-mounting base also features a 60mm-wide contact area, ensuring stable attachment to the truck’s upper right chassis rail and avoiding bracket tilting

The assembly’s core components are crafted from high-strength Q355B steel—chosen for its exceptional tensile strength (≥510 MPa) and impact resistance—ensuring durability in harsh operating conditions. To prevent corrosion (a common issue for under-hood/upper-chassis brackets), all steel parts undergo a three-step anti-corrosion process: first, a zinc phosphate pretreatment (15-17μm thick) creates a porous base for coating adhesion; second, an electrophoretic primer (22-25μm thick) forms a barrier against moisture; finally, a matte-black polyester powder coating (85-95μm thick) adds scratch and chemical resistance. This treatment passes 1200-hour neutral salt spray tests with no red rust formation, making the bracket suitable for trucks operating in coastal (saltwater spray) or snowy (de-icing salts) regions

Exclusively tailored for Dongfeng GX heavy-duty trucks (compatible with 2020+ cargo, long-haul, and dump variants), the 8407172-C6100 adheres strictly to original equipment (OE) specifications. Manufactured using 3D laser scanning of the GX’s upper right chassis rail and bend pipe layout, it achieves dimensional accuracy within ±0.15mm—matching every mounting hole position, pipe cradle contour, and chassis contact point of the factory design. The assembly includes 4 pre-drilled mounting holes (M10 threaded, 18mm depth) that align perfectly with the GX’s chassis reinforcement brackets, eliminating the need for on-site drilling (which weakens chassis integrity). It also features a 10mm offset design that matches the GX’s upper right pipe routing, ensuring the bracket does not interfere with adjacent components (e.g., wiring harnesses, sensor connectors)

The 8407172-C6100 is designed for efficient installation and minimal upkeep, ideal for fleet maintenance teams. It comes with a complete OE-spec hardware kit: 4 grade 10.9 high-strength bolts (with anti-loosening nylon washers), 4 lock nuts, and 4 rubber gaskets (to reduce vibration and prevent metal corrosion). Installation requires only standard hand tools (13mm socket wrench) and can be completed by two technicians in 20-25 minutes: align the bracket’s pipe cradle with the upper right bend pipe, secure the chassis-mounting base to the rail using the bolts, and torque to 45±3 N·m (per Dongfeng’s torque specifications). The rubberized pipe lining and powder-coated steel require no regular maintenance—simply wipe clean with a damp cloth to remove dust or oil buildup—ensuring long-term reliability with minimal effort
