Product Introduction

• Structure: A complete, pre-painted door assembly made from high-strength steel, featuring a reinforced frame, a large window opening, and a pre-installed door lock mechanism. It includes hinge mounts and a door handle cutout for direct installation.

• Performance: Provides a secure, weather-tight seal to protect the cab from wind, rain, and noise. The robust steel construction resists impact and deformation, ensuring long-term durability in harsh operating environments.

Core Function

1. Access & Security: Serves as the primary entry and exit point for the right side of the cab, with a secure locking mechanism to protect the vehicle’s interior.

2. Weather Protection: Creates a tight seal against the cab frame, preventing water, wind, and dust from entering the passenger compartment.

3. Structural Integrity: The reinforced steel construction contributes to the overall rigidity of the cab, enhancing crash safety and reducing vibration.

Customer Case Study

East African Fleet Operator Cuts Downtime by 40% with Door Assembly 6100016C62GY78 Dongfeng

A logistics company operating 120+ Dongfeng trucks across Kenya and Tanzania faced recurring cabin door issues: warped aftermarket panels, misaligned hinges, and premature seal failure. Their maintenance team was spending 4–6 hours per truck on fitment adjustments alone.

After switching to METTLEAD’s Door Assembly 6100016C62GY78 Dongfeng, their workshop reported:

• Installation time reduced from 6 hours to under 2 hours – bolt-on fitment with no grinding or shimming required
• Zero water leakage complaints after monsoon season across 45 replaced units
• Procurement cost reduced by 28% compared to their previous regional supplier
• Repeat order placed within 90 days for an additional 60 door assemblies

The procurement manager noted: “We tested three suppliers before settling on METTLEAD. The Door Assembly 6100016C62GY78 Dongfeng from their factory matched OEM quality at a price point that made financial sense for our entire fleet renewal program.”
