Dongfeng KL trcuk parts front bumper Right bracket 8406162-C3302

Designed to bear the full weight of the front bumper (up to 80kg) and absorb minor impact forces (e.g., from curbs or small debris), the bracket uses high-grade structural steel for exceptional load-bearing capacity. The main body is crafted from 5mm-thick Q345B low-alloy steel (tensile strength 470–630 MPa), which resists bending or deformation even under 150% of the rated load (120kg static weight). The mounting lugs (where the bracket connects to the bumper) are reinforced with 8mm-thick steel plates, welded via robotic MIG welding (fillet weld size 6mm) for maximum joint strength—preventing lug separation during vibration or impact. Unlike thin mild steel or aluminum brackets that crack under stress, this heavy-duty design endures 200,000+ km of driving (including rough roads) without structural failure, ensuring long-term bumper stability

Built to withstand harsh outdoor conditions—including road salt, rain, humidity, and UV radiation—the bracket features a comprehensive anti-corrosion treatment system. First, it undergoes hot-dip galvanization (zinc coating thickness ≥85μm) to create a base barrier against rust. Then, it receives an electrostatic epoxy primer (60μm thickness) for enhanced adhesion, followed by a high-gloss polyester topcoat (70μm thickness) in the factory-matched black color. This three-layer coating passes 1,000 hours of neutral salt spray testing (equivalent to 8 years of road salt exposure) without rust, peeling, or fading. The mounting holes are also coated with anti-seize compound to prevent thread corrosion, ensuring easy bolt removal during future maintenance. Unlike single-layer painted brackets that rust within 1–2 years, this design maintains structural integrity and appearance for 6+ years

Engineered to simplify installation for technicians or DIY owners, the bracket includes precision-machined mounting points and alignment features. All bolt holes (6 total: 4 for frame attachment, 2 for bumper connection) are drilled with H9 tolerance (ensuring perfect bolt fit) and deburred to avoid damaging bolts or threads. The bracket also has two laser-etched alignment marks that line up with reference points on the frame rail and bumper—eliminating guesswork and reducing installation time by 30%. Unlike brackets with misaligned holes that require reaming or filing, this design allows for direct, tool-free positioning (using standard hand tools: socket wrench, torque wrench) and secure tightening to OEM-specified torque (45 N·m for frame bolts, 30 N·m for bumper bolts). Installation takes 25–30 minutes, even for first-time users

The bracket is designed to work seamlessly with the Dongfeng KL’s front bumper system, including fog lights, lower grille, and impact absorbers. Its curved profile (matching the bumper’s contour) ensures no interference with fog light wiring or grille mounting tabs, preserving the functionality of all front-end components. Additionally, the bracket’s structure includes a slight flex zone (near the bumper connection) that absorbs minor impact energy (e.g., low-speed collisions with curbs) without permanent deformation—protecting both the bracket and the frame rail from damage. It is also compatible with aftermarket bumper accessories (e.g., bull bars) that attach to the original mounting points, providing flexibility for customization. Each unit undergoes strict quality checks: dimensional verification via CMM (Coordinate Measuring Machine), load-bearing testing, and impact simulation. Backed by a 24-month warranty against manufacturing defects (e.g., bending, rusting, hole misalignment), it provides Dongfeng KL truck owners with a reliable, long-lasting front bumper support solution
