Dongfeng GX Clock spring assembly 3774150-C6200

The part number 3774150-C6200 is a unique official identifier authorized by Dongfeng, distinguishing this genuine clock spring assembly from counterfeit or low-quality alternatives. By inputting this number into Dongfeng’s official parts database, users can access comprehensive details: production batch, manufacturing date, quality inspection records (e.g., conductivity and durability tests), and authorized supply channels—enabling full lifecycle traceability. This traceability is critical for safety: if the clock spring fails (e.g., broken circuits), the part number helps track production defects to prevent safety risks. For workshops, it simplifies inventory management and procurement, ensuring accurate selection of GX-specific units. The number is clearly laser-etched on the assembly’s housing, remaining legible even after long-term exposure to dust and temperature changes, facilitating easy authenticity checks

As a core electrical transmission component, this clock spring assembly ensures reliable current transfer for the Dongfeng GX’s steering-wheel-mounted functions. It uses high-conductivity copper alloy contacts (tinned to resist oxidation) with low resistance (≤30mΩ), maintaining stable power supply to the airbag, horn, and audio controls—even during maximum steering rotation. The spiral cable inside is made of flexible, high-temperature-resistant material (able to withstand 120°C) that avoids breakage from repeated twisting. It also features a redundant circuit design for the airbag system, providing a backup path to prevent failure in emergency situations. Tested under 100,000+ steering rotation cycles (simulating 5 years of use), the assembly maintains consistent conductivity, ensuring critical functions like airbag deployment and horn operation work flawlessly

To withstand the steering system’s dynamic environment (constant rotation, vibration), this clock spring assembly adopts a robust, anti-failure structure. The outer housing is made of flame-retardant ABS plastic (meeting UL94 V-0 standard) that resists impact and high temperatures, protecting internal components from damage. The spiral cable is reinforced with fiberglass threads to prevent stretching or snapping during rotation, and the contact points are coated with wear-resistant nickel plating to extend service life. It also includes a rotation limit device that prevents over-rotation (exceeding the design angle), avoiding cable breakage. Every unit undergoes 100% quality testing: conductivity checks, rotation cycle tests, and environmental tests (vibration, high/low temperature), ensuring no defects. This durability guarantees a service life of 8-10 years, matching the vehicle’s expected lifespan

Designed for safe and efficient replacement, this clock spring assembly features user-friendly installation with clear safety protocols. It follows the original mounting design: alignment marks on the housing match the steering column, ensuring correct positioning before tightening 2-3 screws (using a standard Phillips screwdriver). A bilingual (English/Chinese) manual is included, providing step-by-step instructions—including critical steps like disconnecting the battery before installation to avoid airbag activation. The assembly also has a pre-installed locking tab that fixes the spiral cable in place during installation, preventing damage from accidental rotation. Even experienced technicians can complete replacement in 30-40 minutes. Unlike non-OE units that lack safety guidance, this assembly ensures proper installation, avoiding safety hazards and ensuring compliance with automotive safety standards
