Dongfeng GX front cover Left lock assembly 5301609-C6100

The part number 5301609-C6100 is an official, unique identifier from Dongfeng, distinguishing this lock assembly from counterfeits. Inputting it into Dongfeng’s official database reveals key details: production batch, manufacturing date, quality inspection records, and authorized suppliers—enabling full traceability. This is vital for quality control: if issues arise, the number tracks the production chain to resolve problems quickly. For maintenance teams, it simplifies inventory management and procurement, ensuring correct part selection. The number is also clearly engraved on the assembly’s shell with wear-resistant marking, remaining legible long-term for easy authenticity verification

As a core safety component, this assembly features multi-layered protection for stable locking and unlocking. When closed, the main locking tongue engages firmly with the striker plate to resist vibration/wind, while the auxiliary tongue acts as a backup if the main tongue fails—preventing sudden front cover opening while driving. Unlocking requires the internal lever or external emergency device, avoiding misoperation or unauthorized access. It also has an anti-pry structure with non-linear internal components to deter theft. Tested over 10,000 cycles under extreme conditions (-30°C to 80°C, high humidity), it maintains consistent performance, safeguarding the engine compartment and internal parts long-term

Crafted for 8-10 years of service, the assembly uses high-quality materials and advanced processes. The outer shell is glass fiber-reinforced PA66 (tensile strength 85MPa, impact strength 5kJ/m²) to resist aging, UV, and chemicals (oil, coolant). Internal locking tongues/rods are high-carbon steel (S45C) quenched to HRC 45-50, ensuring wear resistance—after 50,000 cycles, wear is <0.1mm. Stainless steel (304) springs prevent rust. Manufacturing includes precision injection molding (±0.05mm tolerance), CNC machining, and automated assembly. Every unit undergoes 100% inspection (appearance, function, durability) to guarantee quality

Designed for ease, this assembly follows OE mounting standards—all holes align with Dongfeng GX’s brackets, and interfaces match the original, no drilling/welding needed. It works with standard tools (Phillips screwdriver, 10mm wrench). A bilingual (English/Chinese) manual provides step-by-step guides, diagrams, and torque specs (8-10 N·m), letting even novice users install it in 20-30 minutes. Clear “UP/FRONT” markers prevent wrong installation. Compared to non-OE parts (1-2 hours to install), it cuts time and labor costs—benefiting workshops (higher efficiency) and owners (no professional fees)
