Product Introduction

• Structure: Integrally molded from high-strength PP engineering plastic with a matte black anti-scratch finish, adopting an arc-shaped streamline design adapted to the vehicle chassis and wheel contour. It features integrated snap-fit buckles and bolt mounting holes for double fixation, reinforced rib structures at stress points, and reserved matching grooves for the fender rubber sealing belt.

• Performance: The high-quality PP material has excellent impact resistance, aging resistance and low temperature resistance, can withstand the impact of road stones and flying debris without cracking, and resist UV radiation and rain erosion without fading or deformation. The reinforced rib design enhances the structural rigidity of the cover, avoiding deformation under long-term wind pressure and vehicle vibration; the double fixation structure ensures stable installation without loosening and abnormal noise.

Core Function

1. Fender Top Protection: Covers the top gap of the rear wheel fender, effectively blocking road dust, mud, stones and rainwater from splashing into the fender inner cavity and chassis upper parts, reducing the corrosion and wear of chassis components.

2. Aerodynamic Optimization: The streamline arc design reduces the wind resistance generated by air flow passing through the fender top during vehicle driving, and weakens the wind noise at the wheel position, improving the vehicle’s aerodynamic performance and driving comfort.

Top Cover WG9719950155 Sinotruk Sitrak – OEM-Grade Cab Component for Heavy-Duty Trucks

When your Sitrak truck fleet demands a reliable replacement for the cab top cover, precision fitment and material durability aren’t optional—they’re essential. The Top Cover WG9719950155 is an OEM-specification cab exterior panel engineered specifically for Sinotruk Sitrak heavy-duty vehicles. Manufactured under strict quality control at our China-based facility, this component delivers the exact dimensional accuracy and surface finish your maintenance team expects, while our factory-direct pricing keeps your procurement costs predictable.

At Mettlead, we’ve supplied thousands of Sitrak cab parts to fleet operators and distributors across Africa, the Middle East, Southeast Asia, and Central Asia.

Key Features and Buyer Benefits

Precision OEM Fitment

The Top Cover WG9719950155 is produced to match the original Sinotruk Sitrak factory specifications. Consequently, it installs directly onto the cab roof structure without requiring additional trimming, drilling, or modification. This bolt-on fitment reduces workshop downtime significantly—meaning your trucks return to revenue-generating routes faster.

Durable Material Construction

Crafted from high-strength stamped steel with anti-corrosion surface treatment, this top cover resists road debris impact, UV degradation, and moisture penetration. In other words, it maintains structural integrity and appearance across harsh operating environments, from desert heat to tropical humidity.

Strict Quality Assurance

Every unit undergoes dimensional inspection, surface finish verification, and fitment sampling before shipment. Our defect rate remains below 0.3%, which ensures you receive parts that meet your quality expectations on the first delivery—without the hassle of returns or rework.

Factory-Direct Cost Advantage

By sourcing directly from our manufacturing base in China, you eliminate middleman markups. Most buyers report 20–35% cost savings compared to purchasing through regional distributors. Furthermore, we offer flexible payment terms and secure transaction methods tailored to international B2B trade.

White-Label and Custom Packaging Available

If you’re a distributor building your own aftermarket brand, we support white-label packaging with your logo, part numbers, and branding materials. This capability helps you maintain brand consistency across your product catalog without investing in separate packaging infrastructure.

Customer Case Study – Sitrak Top Cover WG9719950155 Bulk Order

In early 2024, a fleet maintenance company based in Tanzania reached out to Mettlead with an urgent requirement. They managed over 60 Sinotruk Sitrak tractor units operating on the Dar es Salaam–Dodoma corridor, and seasonal hailstorms had damaged the cab roof panels on 14 trucks simultaneously. Their local suppliers quoted 6–8 weeks delivery with inconsistent part quality.

Frequently Asked Questions – Top Cover WG9719950155

Is the Top Cover WG9719950155 an exact OEM replacement for Sitrak trucks?

Yes. This top cover is manufactured to match the original Sinotruk factory dimensions, mounting hole positions, and surface coating specifications. It functions as a direct bolt-on replacement, so no welding or custom fabrication is needed during installation.

What material is the Top Cover WG9719950155 made from, and how does it resist corrosion?

The panel is stamped from cold-rolled steel and then treated with an electrophoretic (cathodic electrocoat) primer. This coating process provides excellent corrosion resistance even in humid or salt-spray environments, extending the service life of the component considerably.

Which Sitrak truck models does this top cover fit?

The WG9719950155 is compatible with the Sitrak C7H, C5H, and G7 series cab platforms. If you’re unsure about compatibility with a specific variant, send us your vehicle VIN or cab model number and our technical team will confirm fitment before you order.

Can I order the Top Cover WG9719950155 with my own brand packaging?

Absolutely. We offer full white-label packaging services including custom carton printing, branded labels, and your own part numbering system. This is particularly popular with aftermarket distributors who want to maintain consistent branding across their Sitrak parts inventory.

What is the typical lead time for this top cover?

When the part is in stock, we ship within 3–5 working days. For larger orders or custom-packaged batches, expect 7–12 working days depending on quantity. We always confirm exact timelines before order confirmation so there are no delivery surprises.

How is the Top Cover WG9719950155 packaged for international shipping?

Each panel is individually wrapped in protective film, then placed in reinforced export cartons with corner guards and foam buffers. This packaging protocol prevents surface scratches and edge dents during transit—a common issue with sheet metal cab parts shipped internationally.
