Dongfeng GX/KX truck parts Shield A - Left Chassis Wiring Harness 3724461-H0100

Serving as a critical protective barrier, this wiring harness shield defends the left chassis’s electrical system against diverse operational hazards. Its robust structure shields the harness from physical damage caused by road debris, gravel and rocks encountered during long-haul trips. It also effectively blocks moisture, dust, mud and corrosive substances like road salt or chemicals, preventing short circuits, insulation degradation and electrical failures. Additionally, it minimizes abrasion between the harness and adjacent chassis components such as metal brackets or moving parts, extending the electrical system’s service life. Whether navigating off-road sites, snowy highways or humid coastal areas, the shield keeps the harness intact, reducing costly breakdowns and ensuring reliable vehicle operation.

Crafted from high-strength, glass fiber-reinforced PP plastic, this wiring harness shield is built to withstand commercial trucking rigors. The reinforced material delivers exceptional tensile strength and rigidity, resisting deformation, cracking or breaking even under extreme mechanical stress—such as collisions with large debris or constant driving vibrations. It handles extreme temperatures from -40°C to 85°C, maintaining structural stability in frigid northern and scorching southern climates. Unlike low-grade plastics prone to UV degradation, the shield’s surface features an anti-UV coating to prevent fading, brittleness and aging from prolonged sunlight exposure. This heavy-duty construction ensures long-term durability, cutting down on frequent replacements and lowering maintenance costs for truck operators.

This left chassis wiring harness shield boasts a user-friendly design that streamlines installation and maintenance. Weighing only 0.8kg, its lightweight yet sturdy build allows easy handling without specialized lifting equipment. It adopts a modular structure with pre-drilled mounting holes that align perfectly with the chassis’s original fastener points, enabling mechanics to finish installation in under 30 minutes with standard tools. The snap-fit and bolt-on combination also allows quick removal and reinstallation, facilitating convenient access to the harness for inspections, repairs or upgrades—no damage to the shield or wiring system. Unlike complex protective covers requiring disassembly of multiple components, this optimized design minimizes downtime, boosting operational efficiency for fleet managers.

As a premium replacement part for Dongfeng GX/KX trucks, this wiring harness shield (part number 3724461-H0100) undergoes comprehensive quality control testing to meet or exceed OEM standards.
