DONGFENG KC cab assy 5000012-C4B02 with National VI emissions

Tailored exclusively for Dongfeng KC series heavy-duty trucks (covering 6×4, 8×4, and 4×2 drive configurations), the cab assembly (overall dimensions: 2480mm×2150mm×2080mm) features a frame-mounted structure with 6-point rubber shock absorbers that align perfectly with the original chassis rails. Its mounting hole positions (spaced 1850mm longitudinally and 1920mm transversely) and bolt specifications (M16×50 high-strength bolts) match the KC chassis’s original design, eliminating the need for frame modification. Additionally, the cab’s front-end interface (including radiator support, bumper mounting points, and headlight brackets) is 100% consistent with the original KC cab, ensuring compatibility with all factory-installed front-end components

The cab’s main frame is constructed from high-strength low-alloy steel (Q345) with a 1.5mm-2.0mm thick outer panel and reinforced door pillars (3mm thick steel plates), achieving a static torsional stiffness of 28,000 N·m/rad—providing excellent resistance to deformation under heavy loads or road vibrations. The roof and floor are reinforced with cross beams (spacing: 350mm) to enhance structural integrity, while the cab’s welding joints (processed via robotic arc welding) undergo 100% visual inspection and ultrasonic flaw detection to ensure no cracks or weak points. The exterior is coated with a 3-layer anti-corrosion system (electrophoretic primer + intermediate coat + topcoat), resisting salt spray corrosion for over 800 hours (per GB/T 10125-2021) to withstand harsh working environments like construction sites or coastal areas

Designed to meet Dongfeng’s safety standards for heavy-duty truck cabs (DFM-S-012-2023), the assembly includes multiple safety enhancements:

Passive Safety: Equipped with a reinforced front collision beam (2mm thick high-strength steel) and energy-absorbing steering column mounting bracket, which can absorb up to 30% of impact energy in frontal collisions to protect the driver’s cabin space.Active Safety: Integrates mounting points for a factory-installed airbag system (driver’s side airbag) and anti-lock braking system (ABS) wiring harness, with pre-drilled holes for side impact sensors—supporting the truck’s active safety functions.Occupant Protection: The cab’s floor is lined with a 5mm thick sound-insulating and shock-absorbing rubber mat, reducing road noise by 15-20dB and minimizing vibration transmission to the driver’s seat, enhancing driving comfort and reducing fatigue during long-haul trips

The cab assembly comes with a fully equipped interior tailored for driver comfort and operational efficiency:

Driver’s Seat: A high-back air-suspension seat (with 6-way adjustability: front/rear, height, and lumbar support) that reduces vibration and provides optimal lumbar support for drivers during long shifts.Instrument Panel: A digital-analog integrated instrument cluster (compatible with National VI emissions monitoring) that displays real-time data—including engine speed, fuel consumption, DPF regeneration status, and SCR urea level—ensuring the driver can monitor emissions system performance at a glance.
