Electrical system
The chassis distribution box assembly (Part No.: 3771110-H12B1) serves as the core power distribution hub for Dongfeng GX’s chassis electrical system, integrating 12+ dedicated circuits to supply power to key components (e.g., brake system, suspension control, chassis sensors). It features pre-installed fuses and relays with clear labeling, enabling quick identification of each circuit’s function (e.g., "ABS Power," "Suspension Control")—simplifying fault diagnosis. The centralized design reduces scattered wiring under the chassis, minimizing the risk of wire wear or short circuits caused by road debris
Product Attributes
Warranty: 1 YEARS Part name: Chassis distribution box assembly 3771110-H12B1
PRODUCT DESCRIPTION
IP6K9K High-Level Protection: Resistant to Harsh Chassis Environments
Engineered for the harsh under-chassis environment, the distribution box achieves an IP6K9K protection rating—providing complete dust tightness (IP6X) and resistance to high-pressure, high-temperature water jets (IP9K, 80℃, 80-100 bar). The box body is sealed with a double-layer silicone gasket, and all wire entry points use waterproof cable glands, effectively blocking water, mud, and road salt from entering the interior. This protection ensures stable circuit operation even in heavy rain, off-road driving, or snowy conditions, avoiding short circuits or component corrosion
OE-Spec Fitment: Seamless Integration with Dongfeng GX Chassis
Strictly manufactured to Dongfeng GX’s original equipment (OE) specifications, the assembly features precision-machined mounting brackets and a custom wiring harness interface. The brackets align perfectly with the chassis frame’s mounting points, ensuring no vibration or displacement during driving (tested to withstand 50Hz continuous vibration). The plug-and-play wiring connector matches the vehicle’s factory chassis harness exactly, requiring no cutting or rewiring—maintaining the original electrical system’s integrity and safety
High-Durability Structure: Withstand Extreme Conditions
The distribution box body is made of glass fiber-reinforced PA66 nylon plastic, which offers high tensile strength (≥80MPa) and impact resistance (passes -40℃ low-temperature impact test). The internal fuse/relay slots are made of heat-resistant PBT plastic (operating temperature: -40℃ to 120℃), preventing deformation or melting caused by long-term current heating. All metal components (e.g., terminal pins) are plated with tin-copper alloy, resisting corrosion from road salt or humidity and ensuring stable electrical conductivity (contact resistance ≤10mΩ)
Easy Maintenance & Fault Diagnosis: Reduce Downtime
The assembly features a flip-up, tool-free cover—allowing quick access to fuses and relays without disassembling the entire box. Each fuse/relay slot is marked with a clear identifier (e.g., amperage, function) and color-coded for easy recognition, enabling fast replacement of faulty components. Additionally, the box is equipped with a built-in voltage detection terminal, allowing technicians to test chassis circuit voltage directly (without disconnecting wires) to speed up fault location. This design reduces maintenance time by 40% compared to traditional distributed chassis circuits
TECHNICAL SUPPORT
1. Accessories selection consultation
- Provide ** intelligent selection tools ** (such as parts matching query system), input the vehicle model VIN code or engine model to match the corresponding parts number, reducing the selection error rate.
The technical team is available online 7×12 hours to answer technical questions about accessories (such as material compatibility and installation processes).
2. Customized development support
We offer specialized R&D services for special market demands (such as heat dissipation accessories for high-temperature regions in the Middle East and dedicated suspension components for road conditions in Africa), and complete sample delivery within six weeks.
3. Training and Technical materials
Provide remote/on-site training for the customer's after-sales team (such as diagnosis of electrical control accessories and DPF regeneration operation), along with multilingual versions of the "Accessories Installation Manual" and "Troubleshooting Guide".
4. Quality Traceability and Improvement
Through the QR code traceability system (one product, one code), track the production batch of accessories and the source of raw materials, respond quickly to quality complaints and initiate improvement processes.
AFTER-SALES AND LOGISTICS SUPPORT
After-sales service
Quality Assurance Policy
-The warranty period for original factory parts is 12 months (counting from the date of signature for receipt), covering material defects, process issues, and man-made damage.
- Provide "Localized Express repair Service" : Cooperate with third-party repair networks in markets such as Southeast Asia and the Middle East, and deliver emergency parts to designated repair points within 4 hours.
Return and Exchange Process
-The customer is required to submit the test report (such as a third-party appraisal) within the warranty period. After confirmation by Dongfeng, a reissue or refund will be arranged within 5 working days.
Logistics support
Warehouse Layout
-Five major regional accessory centers have been established globally (Southeast Asia, the Middle East, Africa, South America, and Europe) to achieve "next-day delivery" for mainstream accessories (covering customers within the regions).
Emergency Logistics Plan
-Emergency parts can be directly delivered within 48 hours via the "Dongfeng Exclusive Aviation Special Line" (such as engine ECU, brake valves and other key components).
Packaging Optimization
-Use shockproof and moisture-proof packaging (such as honeycomb cartons + pearl cotton), and reinforce fragile parts (such as glass, sensors), keeping the damage rate within 0.5%.
