Dongfeng Xinjiang X7 truck parts bumper Secondary step bracket assembly 8406186-TXGG01Y

Built to withstand the weight of drivers and occasional heavy loads, this bracket assembly features a high-strength steel structure with a maximum load-bearing capacity of 150kg—exceeding the average weight of adult users and accounting for tools or gear carried during entry. The main support frame is made of 3mm-thick cold-rolled steel (tensile strength ≥500MPa), which resists bending or deformation even under repeated stepping. Reinforced triangular gussets are welded at key stress points (e.g., bracket-to-bumper joints, step attachment areas) to distribute weight evenly, avoiding localized stress that could lead to cracking. This robust design ensures the secondary step remains stable during daily use, preventing wobble or collapse that could cause driver injuries. For Dongfeng Xinjiang X7 drivers who frequently enter and exit the cab, this safety-focused bracket provides reliable support

Engineered to withstand the tough operating environments of trucks (e.g., rain, snow, road salt), the bracket assembly features a multi-layer anti-corrosion coating system. First, a zinc phosphate pretreatment layer is applied to the steel surface to block rust at the substrate. Then, a high-temperature electrostatic powder coating (thickness: 70-90μm) is baked on, providing a scratch-resistant, waterproof finish that resists peeling or fading. This coating passes 600-hour salt spray testing (per ASTM B117 standards) without rusting, ensuring durability in coastal areas or winter roads with salt. Additionally, all mounting hardware (bolts, washers) included with the assembly are galvanized steel, further enhancing corrosion resistance. These features extend the bracket’s service life to over 6 years, reducing replacement frequency for X7 truck owners

Beyond basic load-bearing, the bracket assembly incorporates ergonomic and protective details to improve functionality for Dongfeng Xinjiang X7 users. The step attachment surface is designed with a non-slip texture (if paired with a step pad) and a 5mm raised edge, preventing the driver’s foot from slipping off during wet or muddy conditions. The bracket’s edges are rounded and deburred, eliminating sharp corners that could cause scratches or injuries. It also acts as a protective buffer for the bumper’s lower section, absorbing minor impacts from road debris (e.g., stones, curbs) to minimize damage to the bumper’s plastic cover. Additionally, the bracket’s compact design avoids interference with the truck’s front tires or steering components, ensuring no impact on driving performance. These thoughtful details make the assembly both safe and practical for daily use

Designed for user-friendly installation, the bracket assembly requires no specialized tools or mechanical expertise—allowing X7 truck operators or repair shops to complete setup quickly. The package includes 6 high-tension M8×25 bolts, lock washers, and nuts that match the X7’s factory bumper thread specifications. Installation steps are straightforward: align the bracket’s mounting holes with the pre-drilled points on the bumper; secure the bracket with the included bolts, tightening them to the recommended torque (28N·m); and attach the secondary step pad (using the factory’s existing fasteners, if applicable). The entire process takes less than 30 minutes. Maintenance is equally simple—occasional cleaning with a damp cloth to remove dirt or salt, and visual checks for loose bolts, ensure long-term performance. This design minimizes truck downtime, critical for commercial drivers relying on their Dongfeng Xinjiang X7 for daily transportation tasks
