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 frame.

• Performance: Effectively blocks mud, stones, and road debris from damaging the rear wheel, brake system, and chassis components. The durable plastic construction resists corrosion, UV damage, and impact, ensuring long service life in harsh operating conditions.

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

Core Function

1. Debris Protection: Shields the left rear wheel well, brake lines, and chassis from mud, stones, and corrosive road salts, extending their service life.

2. Spray Reduction: Reduces water and debris spray from the rear wheel, improving visibility for following vehicles and enhancing road safety.

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

Rear Left Mudguard 8403059C6210 Dongfeng – OEM-Grade Protection for Your Fleet

Every heavy-duty truck that rolls off the highway carries thousands of miles of road debris, water spray, and gravel impact on its body panels. The Rear Left Mudguard 8403059C6210 Dongfeng stands as the first line of defense for your vehicle’s undercarriage, chassis components, and trailing traffic. Engineered to OEM specifications, this mudguard delivers the exact fit, material resilience, and aerodynamic profile that Dongfeng engineers intended — without the inflated dealer markup.

METTLEAD Truck Parts supplies this genuine-equivalent component directly from certified production lines in China, giving fleet managers and procurement professionals access to factory-direct pricing, verified quality, and rapid global logistics.

Key Features and Buyer Benefits

Precision OEM Fitment

The 8403059C6210 mudguard mirrors the original Dongfeng design tolerances down to every mounting hole, contour radius, and edge profile. It bolts directly onto the rear left wheel arch without modification, trimming, or adapter brackets — saving your workshop hours of labor on every installation.

High-Impact Material Construction

Manufactured from reinforced composite polymer (or stamped steel, depending on the OEM variant), this mudguard resists UV degradation, stone chipping, chemical splash, and temperature cycling from −40 °C to +80 °C. It stays rigid where rigidity matters and flexes where impact absorption is critical.

Corrosion and Weather Resistance

A factory-applied protective coating shields the surface against moisture ingress, road salt, and oxidation — extending the service life well beyond aftermarket alternatives that lack equivalent surface treatment.

Cost Efficiency at Scale

By sourcing directly from METTLEAD’s production network, you eliminate intermediary markups. Bulk orders receive tiered pricing that can reduce your per-unit cost by up to 15–25 % compared to regional distributors.

Reduced Maintenance Downtime

A properly fitted rear left mudguard prevents debris damage to brake lines, air tanks, and suspension components mounted behind the rear axle. One mudguard protects thousands of dollars’ worth of critical parts.

Technical Specifications

Application Vehicle Scenarios

The Rear Left Mudguard 8403059C6210 is designed to serve across multiple Dongfeng heavy and medium-duty truck platforms, including:

• Dongfeng KL Series (Kinland) — Long-haul tractor units operating on highways where high-speed debris impact is constant.
• Dongfeng KR Series — Regional distribution trucks exposed to mixed urban and rural road conditions.
• Dongfeng VL Series — Construction-site logistics vehicles that face extreme gravel and mud exposure daily.
• Dongfeng Tianjin Series — Medium-duty platforms used in municipal and cargo transport fleets.

Whether your trucks haul aggregate across mining roads in Africa, navigate monsoon-soaked highways in Southeast Asia, or endure freeze-thaw cycles in Central Asia, this mudguard is built to protect — kilometer after kilometer.

OEM / ODM Capability

White-Label and Custom Packaging

METTLEAD supports full white-label packaging for distributors who sell under their own brand. Your logo, part numbering system, and barcodes can be printed directly on the box — giving your customers a seamless brand experience without revealing the supply origin.

Custom Material or Finish Options

Need a thicker gauge for extreme off-road environments? Require a specific color-matched finish for fleet uniformity? Our engineering team works with you to adjust specifications within viable production parameters.

Strict Quality Control

Every batch undergoes dimensional inspection, surface quality assessment, and fitment verification against original Dongfeng templates. Defect rates are held below 0.3 % across production runs — a standard many regional suppliers cannot match.

Flexible Order Quantities

From sample orders of 5–10 pieces for testing, to container-load volumes for national distribution, METTLEAD scales production without compromising delivery timelines.

Client Case Study: East African Fleet Operator

A fleet management company operating 120+ Dongfeng KL tractors across Kenya and Tanzania faced recurring damage to rear axle brake assemblies. Root-cause analysis revealed that worn and ill-fitting aftermarket mudguards were allowing road debris to impact vulnerable components behind the rear wheels.

After switching to the Rear Left Mudguard 8403059C6210 Dongfeng sourced through METTLEAD, the operator reported a 40 % reduction in rear-axle component claims within six months. Installation time dropped from 45 minutes (with trimming and drilling) to under 15 minutes per unit thanks to precise OEM-hole alignment. The procurement manager noted that per-unit cost was 22 % lower than their previous regional supplier, while fitment accuracy eliminated rework entirely.

“We stopped gambling on generic mudguards. The 8403059C6210 fits like it came off the Dongfeng line — because it essentially did.” — Fleet Procurement Manager, Nairobi

Frequently Asked Questions

Is the Rear Left Mudguard 8403059C6210 an original Dongfeng part or an aftermarket equivalent?

It is manufactured to OEM specifications using the same tooling standards and material grades as the original Dongfeng component. It delivers identical fitment and performance while being priced at factory-direct levels.

Will this mudguard fit other Dongfeng models beyond the KL series?

Part number 8403059C6210 is specific to certain Dongfeng platforms. Cross-referencing your vehicle’s chassis number with our parts catalog ensures exact compatibility. Contact our team with your VIN or existing part number for confirmation.

What is the expected service life of this rear left mudguard?

Under normal highway and regional transport conditions, the mudguard typically delivers 3–5 years of service before requiring replacement. Severe off-road or mining applications may reduce this to 18–30 months depending on impact exposure.

Can I order just the rear left side, or must I buy a pair?

The 8403059C6210 is sold as an individual rear left unit. You can order single pieces, pairs, or bulk quantities — whichever your maintenance schedule demands.

How does METTLEAD ensure this mudguard matches the original dimensions?

Each production batch is checked against a Dongfeng OEM reference sample using coordinate measuring equipment. Mounting hole positions, curvature profiles, and edge clearances must fall within ±0.5 mm tolerance to pass inspection.

What packaging options are available for resellers?

Neutral packaging (no branding), METTLEAD-branded packaging, or fully custom-printed boxes with your company logo and part number are all available. Minimum quantities apply for custom packaging runs.
