Original factory Dongfeng DFAC cab assy 5000012-LD4001

Unlike bare cab shells, this cab assembly arrives pre-integrated with critical factory-installed components to streamline maintenance and rebuild processes. Typical pre-fitted parts include the complete dashboard assembly (with instrument cluster mounting brackets, HVAC ducting, and wiring harness connectors), door assemblies (with hinges, locks, and window regulators pre-installed), front windshield frame (with weatherstripping), and interior structural components (such as seat rails, steering column mounts, and floor pans with sound deadening material). This fully assembled design reduces on-site installation time by 50–60% compared to assembling components from scratch, minimizing truck downtime—a critical advantage for commercial fleets dependent on vehicle availability

Constructed with a high-strength steel frame (using Q345 or equivalent automotive structural steel), the cab assembly features a reinforced safety cell design—including thickened A/B/C pillars, cross-braced roof beams, and impact-absorbing front/rear crumple zones. This structure complies with Dongfeng’s commercial vehicle safety standards and international benchmarks (e.g., ECE R29 for cab strength), providing enhanced protection for drivers in frontal or side collisions. Additionally, the floor pan is reinforced with anti-vibration ribs to reduce road-induced vibration transfer to the interior, improving driver comfort during long-haul operations, while the steel frame’s zinc-phosphate pre-treatment and electrophoretic coating ensure superior rust resistance against road salt, moisture, and harsh environmental conditions

The cab assembly features a factory-applied exterior paint finish (matching DFAC’s original color codes, e.g., standard white, silver, or custom fleet colors per configuration) with a multi-layer coating system: corrosion-resistant primer, color base coat, and scratch-resistant clear coat. This finish resists UV fading, chemical damage (from diesel, road cleaners, or oil), and minor abrasions, maintaining a professional appearance for years. Internally, the cab includes pre-installed interior trim panels (with anti-scratch surfaces), sound-insulating headliners, and waterproof floor coverings—all meeting DFAC’s original quality standards for durability and comfort. The interior is also pre-wired with main harnesses (labeled for easy connection to chassis electrical systems) and pre-fitted with HVAC system components (heater, blower, and ducting) for immediate functionality post-installation

This cab assembly (5000012-LD4001) undergoes rigorous OE quality control testing, including dimensional accuracy verification (via 3D laser scanning to ensure fitment precision), structural load testing (to confirm impact resistance and durability), and environmental testing (exposure to extreme temperatures, humidity, and vibration to simulate long-term commercial use). It complies with key standards such as ISO 9001 (manufacturing quality), GB 7258 (Chinese national standards for motor vehicle safety), and relevant regional regulations (e.g., Southeast Asia’s UN R110 for emissions-related component compatibility). Compliance ensures the cab assembly meets roadworthiness requirements in markets where Dongfeng DFAC trucks operate, while avoiding performance or safety risks associated with non-OE aftermarket cabs (e.g., poor component compatibility, substandard structural integrity, or failed inspections)
