The AZ1642210002+AZ1642210001 doors are manufactured from high‑strength, cold‑rolled steel, ensuring they can withstand impacts and daily use without deforming. The inner panels are precision‑stamped to match the original cab contours, guaranteeing a seamless fit with the cab frame, hinges, and latch mechanisms. Each door includes all original mounting points for mirrors, handles, and window regulators, simplifying installation and ensuring proper alignment.
A rigorous multi‑stage finishing process is applied to each door. After forming, they are thoroughly cleaned and treated with a zinc‑phosphate coating for superior corrosion resistance. A cathodic electrocoat (e‑coat) primer is then applied, followed by a durable, UV‑resistant topcoat that matches the gloss and color of the original finish. This meticulous process ensures the doors resist rust, chipping, and fading, maintaining their appearance and structural integrity for the life of the vehicle.
The door shells are designed with integrated reinforcement beams to meet stringent safety standards, protecting occupants in the event of a side impact. Weatherstripping channels are precisely formed to ensure a perfect seal with the cab, preventing water, dust, and noise intrusion. The doors are supplied as complete assemblies, ready for installation of existing hardware.

Installation of the AZ1642210002+AZ1642210001 doors should be performed with care to ensure proper alignment and finish protection. Begin by safely supporting the vehicle and removing the old doors. Transfer all hardware (hinges, latch, window regulator, glass, handles) to the new doors, using new fasteners where recommended. Clean the cab mounting surfaces and apply anti‑seize to hinge bolts.
Position the new door and loosely install the hinge bolts. Align the door gaps with the cab, fender, and rocker panel, then tighten bolts to the specified torque. Reconnect any electrical wiring for power windows or mirrors. Adjust the latch striker on the cab to ensure smooth closing. The AZ1642210002+AZ1642210001 doors are a direct OEM replacement for SINOTRUK HOWO models with wide‑body, single‑row cabs. Compatibility must be verified by matching the part number with your vehicle’s service manual.
Before final tightening, use masking tape on the door edges to prevent scratching the cab paint during alignment. Apply a coat of wax to the new finish after installation for added protection. Check weatherstrip sealing with a sheet of paper; it should hold firmly when the door is closed.
The multi‑layer coating system, including zinc phosphate pretreatment and e‑coat, provides exceptional resistance to rust caused by road salt, moisture, and chemicals, ensuring the doors last for years.
The factory‑applied topcoat matches the gloss and color of your original HOWO, eliminating the need for painting and ensuring a seamless, professional appearance.
Using genuine OEM doors guarantees a bolt‑on fit with no modifications required, significantly reducing installation time and getting your truck back on the road faster.
Built‑in side impact beams and precision‑engineered latch reinforcements provide superior occupant protection, meeting or exceeding safety standards.
Damaged doors not only detract from your truck’s appearance but can also compromise safety and allow water and dust intrusion. Common reasons for replacement include collision damage, severe rust perforation, cracks from vibration fatigue, or failed door seals that cannot be corrected by adjustment. During routine inspections, check for rust spots, dents, misalignment, and difficulty in closing. If the structural integrity is compromised or the damage is beyond cosmetic repair, immediate replacement with genuine AZ1642210002+AZ1642210001 doors is essential to restore safety and maintain the vehicle’s value.
Ignoring a damaged door can lead to accelerated rust in the cab, water damage to interior components, and even door detachment in extreme cases. Replacing it promptly with a genuine set restores your truck’s rugged look and ensures long‑term protection.
To maximize the life of your AZ1642210002+AZ1642210001 doors, wash them regularly to remove road salt and abrasive dirt. Inspect the drain holes at the bottom of the doors and keep them clear to prevent moisture buildup. Lubricate hinges and latches periodically with a suitable grease. Touch up any stone chips promptly with matching paint to prevent rust from starting. Check weatherstrips for tears or compression set and replace if necessary to maintain a good seal.
During winter, pay extra attention to the door seals to prevent them from freezing shut. Avoid slamming the doors, as this can misalign the latch and hinges. Always use genuine SINOTRUK HOWO replacement parts for any repairs. Following these practices will help your truck maintain its professional appearance and structural integrity.
