Dongfeng KL trcuk parts front bumper Left bracket 8406161-C3302

Designed to bear the full weight of the front bumper (up to 75kg) and absorb minor impact forces (e.g., curbs, small debris), the bracket uses premium Q345B low-alloy steel for exceptional structural strength. The main body is crafted from 5mm-thick steel (tensile strength 470–630 MPa), capable of withstanding 140% of the rated load (105kg static weight) without bending. The bumper-mounting lugs are reinforced with 7mm-thick steel plates, joined via robotic MIG welding (fillet weld size 5.5mm) to ensure joint integrity—preventing lug separation during road vibration or low-speed impacts. Unlike thin mild steel or aluminum brackets that deform under stress, this heavy-duty design endures 250,000+ km of driving (including rough terrain) without structural failure, maintaining bumper stability for 6+ years

Built to resist harsh outdoor conditions—road salt, rain, humidity, and UV radiation—the bracket features a three-stage anti-corrosion treatment. First, it undergoes hot-dip galvanization (zinc coating thickness ≥80μm) to create a base rust barrier. Next, an electrostatic epoxy primer (55μm thickness) is applied for enhanced coating adhesion, followed by a high-gloss polyester topcoat (65μm thickness) in the factory-matched black color. This system passes 950 hours of neutral salt spray testing (equivalent to 7.5 years of road salt exposure) without rust, peeling, or fading. The mounting holes are treated with anti-seize compound to prevent thread corrosion, ensuring easy bolt removal during maintenance. Unlike single-layer painted brackets that rust within 1–2 years, this design maintains structural integrity and appearance in extreme weather

Engineered for hassle-free installation by technicians or DIY owners, the bracket includes precision-machined features to simplify setup. All 6 mounting holes (4 for frame attachment, 2 for bumper connection) are drilled with H9 tolerance (ensuring perfect bolt fit) and deburred to avoid damaging fasteners. Two laser-etched alignment marks align with reference points on the frame rail and bumper, eliminating guesswork and cutting installation time by 25%. Unlike brackets with misaligned holes that require reaming, this design allows direct attachment using standard hand tools (socket wrench, torque wrench) to OEM-specified torque: 42 N·m for frame bolts, 28 N·m for bumper bolts. Installation takes 20–25 minutes, even for first-time users

The bracket is optimized to work seamlessly with the Dongfeng KL’s front-end system, including fog lights, lower grille, and impact absorbers. Its curved profile matches the bumper’s contour, ensuring no interference with fog light wiring or grille mounting tabs—preserving component functionality. A slight flex zone near the bumper connection absorbs minor impact energy (e.g., hitting curbs) without permanent deformation, protecting both the bracket and frame rail. It is also compatible with aftermarket accessories (e.g., bull bars) that use original mounting points, offering customization flexibility. Each unit undergoes strict quality checks: dimensional verification via CMM, load-bearing testing, and impact simulation. Backed by a 24-month warranty against defects (bending, rusting, hole misalignment), it provides Dongfeng KL truck owners with a reliable front bumper support solution
