Product Introduction

• Structure: A heavy-duty, one-piece molded plastic assembly with a reinforced ribbed design for impact resistance. It features precision-engineered mounting holes and integrated brackets for secure attachment to the chassis and fender.

• Performance: Effectively blocks mud, stones, and road debris from entering the wheel well and damaging the chassis, brake lines, and wiring. The durable plastic construction resists corrosion and impact, ensuring long service life in harsh conditions.

• Design: Directly interchangeable with original equipment mudguards, engineered to match the truck’s chassis and fender mounting points for a seamless, factory-like fit.

Core Function

1. Debris Protection: Shields the inner wheel well, chassis components, and wiring from mud, stones, and corrosive road salts, extending their service life.

2. Aerodynamic Enhancement: The streamlined design helps direct airflow, reducing turbulence and drag around the wheel area.

3. Durability: The robust plastic construction withstands impact from road debris and resists UV damage, ensuring reliable performance over time.

Upper Right Inner Mudguard Assembly 8403320C6100 Dongfeng — Wholesale Supply with Factory-Direct Pricing

Protecting the inner wheel arch from road debris, mud, and corrosive moisture is a job that never stops — and neither should your mudguard. The Upper Right Inner Mudguard Assembly 8403320C6100 is purpose-engineered for Dongfeng commercial vehicles, delivering the precise fitment, material durability, and structural integrity that fleet operators and repair workshops demand. As a dedicated wholesale supplier, METTLEAD Truck Parts brings you this critical body component at factory-direct prices with strict quality control that mirrors OEM standards.

Key Features and Benefits for Wholesale Buyers

Precision OEM-Equivalent Fitment

This mudguard assembly carries the original part number 8403320C6100, ensuring bolt-on installation without any modification. Every mounting hole, curvature, and bracket aligns perfectly with Dongfeng cab and chassis geometry, reducing workshop labor time and eliminating costly returns.

Heavy-Duty Material Construction

Manufactured from high-density polyethylene (HDPE) and reinforced composite materials, this inner mudguard resists impact, UV degradation, and chemical exposure from road salts and fuel splashes. It remains flexible in sub-zero temperatures yet rigid enough to hold its shape under sustained highway vibration.

Corrosion and Fatigue Resistance

Unlike bare metal alternatives that rust within months in humid or coastal environments, this assembly is inherently corrosion-proof. The material composition absorbs repetitive stone impacts without cracking, extending service life well beyond standard replacement intervals.

Profit-Friendly Wholesale Structure

• Competitive MOQ: Flexible minimum order quantities tailored to distributors and regional agents.
• Factory-direct pricing: No middlemen — you buy directly from our supply chain in China.
• White-label and custom packaging: Build your own brand with private labeling options.

Technical Specifications

Application — Vehicle Fitment Guide

The Upper Right Inner Mudguard Assembly 8403320C6100 is designed to serve a range of Dongfeng medium and heavy-duty truck platforms. Whether your customers operate long-haul logistics fleets or regional construction haulage, this part covers the workhorses they rely on daily:

• Dongfeng Kinland Series (DFL4251 / DFL4181) — Long-haul tractor units common across Africa, Southeast Asia, and the Middle East.
• Dongfeng KR Series — Medium-duty distribution trucks used in urban and inter-city freight.
• Dongfeng Tianlong (Kingland) KX — Flagship heavy-duty platform favored by large fleet operators.
• Dongfeng Tianjin Series — Versatile medium-duty chassis for mixed-use applications.

In real-world operations, the inner mudguard takes a beating on unpaved mining roads, monsoon-season highways, and dusty construction corridors.

Customer Case Study

How a West African Distributor Scaled Dongfeng Mudguard Sales by 3×

A Lagos-based truck parts wholesaler approached METTLEAD after struggling with inconsistent quality from multiple sourcing agents. Their core complaint: inner mudguard assemblies — including the Upper Right Inner Mudguard Assembly 8403320C6100 — frequently arrived with warped mounting tabs and brittle material that cracked during installation in Nigeria’s hot climate.

After receiving a trial order of 200 units from METTLEAD, their workshop partners reported zero fitment failures and no cracking incidents over a six-month evaluation. The distributor tripled their repeat order within the first year, consolidated all Dongfeng body parts sourcing through METTLEAD, and introduced our white-label packaging for their retail network. Today, the 8403320C6100 mudguard assembly is one of their top-five SKUs by volume.

Frequently Asked Questions

What vehicles does the 8403320C6100 Upper Right Inner Mudguard Assembly fit?

This part is designed for Dongfeng heavy and medium-duty trucks that share the 8403320C6100 specification — primarily the Kinland, Tianlong KX, and KR platforms. Always cross-reference the OEM part number with your specific chassis VIN to confirm compatibility.

Is this mudguard assembly made of metal or plastic composite?

It is manufactured from reinforced HDPE composite. This material outperforms sheet metal in corrosion resistance, weight savings, and impact absorption — which is why Dongfeng uses polymer-based inner mudguards as the factory standard.

How does the 8403320C6100 mudguard handle extreme temperatures?

The material formulation is rated for continuous use between -40°C and +80°C. It stays pliable in harsh winters without becoming brittle and holds dimensional stability under intense equatorial sun exposure.

Can I order this upper right inner mudguard assembly with my own branding?

Yes. METTLEAD offers full white-label and custom packaging services. You supply your brand artwork and part numbering system; we deliver cartons ready for your distribution channel.

What is the typical lead time for wholesale orders of the 8403320C6100?

Standard stock orders ship within 3–7 business days. Custom-packaged or large-volume orders (500+ units) typically require 15–20 days, including packaging production and final QC inspection.

How do I verify the quality before placing a bulk order?
