Product Introduction

• Structure: A set of left and right fairings made of durable, impact-resistant plastic with a high-gloss white painted finish. They feature a contoured, aerodynamic design with integrated mounting points for secure attachment to the cab sides.

• Performance: Reduces aerodynamic drag by smoothing airflow along the cab’s sides, improving fuel efficiency at highway speeds. The robust construction also protects the cab from road debris and minor impacts, while the high-quality paint resists UV fading and scratches.

Core Function

1. Aerodynamic Efficiency: Reduces wind resistance, lowering fuel consumption during long-distance driving.

2. Protection: Shields the cab’s side panels from damage by road debris and minor impacts.

3. Aesthetic Enhancement: Enhances the truck’s exterior appearance with a sleek, finished look.

Side Fairings (Pair) WG1664111051 WG1664111052 for Sinotruk HOWO Heavy-Duty Trucks

When your Sinotruk HOWO truck loses its aerodynamic edge due to cracked or missing side fairings, fuel costs climb and cab integrity suffers. That’s exactly why Mettlead offers this precision-engineered Side Fairings (Pair) WG1664111051 WG1664111052 for Sinotruk HOWO — a direct-fit replacement that restores your truck’s streamlined profile, protects critical underbody components, and keeps your fleet running efficiently. As a China-based factory-direct supplier, we deliver OEM-equivalent quality at wholesale pricing, so procurement managers like you can reduce downtime without stretching budgets.

Why These Sinotruk HOWO Side Fairings Matter for Your Fleet

Side fairings do more than dress up a truck cab. They serve as the first line of defense against road debris, reduce aerodynamic drag, and shield vital wiring harnesses and hydraulic lines routed along the chassis. Without properly fitted fairings, your HOWO trucks face accelerated corrosion, increased fuel consumption, and potential compliance issues during roadside inspections.

Key Functions & Benefits

• Aerodynamic Efficiency: The contoured design of the WG1664111051 (left) and WG1664111052 (right) side fairings smooths airflow between the cab and rear axle, helping reduce fuel consumption by up to 3–5% at highway speeds.
• Underbody Protection: High-impact materials deflect stones, mud, and road debris away from brake lines, electrical harnesses, and fuel tanks.
• Perfect OEM Fit: Manufactured to match original Sinotruk HOWO mounting points — no drilling, cutting, or bracket modification required.
• UV & Weather Resistance: Engineered to withstand harsh sun exposure, heavy rain, and temperature extremes from –40°C to +80°C without cracking or fading.
• Noise Reduction: Fairings dampen wind noise at cruising speed, improving driver comfort during long-haul operations.
• Sold as a Complete Pair: One order covers both the left-side (WG1664111051) and right-side (WG1664111052) fairings, ensuring color and texture consistency.

Customer Case Study — Bulk Side Fairing Order for East African Fleet

In early 2024, a logistics company operating 120 Sinotruk HOWO A7 tractor heads across Kenya and Tanzania reached out to Mettlead. Their challenge? Over 60% of their fleet had cracked or missing side fairings (WG1664111051 and WG1664111052) after just two rainy seasons on unpaved rural routes. Replacement from local markets proved unreliable — poor fitment, brittle materials, and inconsistent color made those aftermarket options a waste of money.

After receiving sample pairs from Mettlead, the client’s maintenance team confirmed perfect bolt-on alignment and noticeably higher material density compared to their previous supplier. They subsequently placed a blanket order for 150 pairs of HOWO side fairings with white-label packaging bearing their company logo. Delivery was completed in three batches over six weeks via Mombasa port, and the client reported zero fitment rejections across the entire shipment.

This is the kind of partnership we build every day — solving real procurement headaches for fleet managers who need Sinotruk HOWO side fairings that actually last.

Frequently Asked Questions — Side Fairings WG1664111051 & WG1664111052

Are these side fairings genuine Sinotruk OEM parts or aftermarket?

These are high-quality aftermarket replacement side fairings manufactured to OEM specifications. They match the original WG1664111051 (left) and WG1664111052 (right) part numbers in dimensions, mounting points, and material grade — ensuring a drop-in fit without modifications.

Will the WG1664111051 and WG1664111052 fairings fit my specific HOWO model year?

These part numbers cover most Sinotruk HOWO cab configurations produced from 2010 onward, including A7, T7H, and N7 variants. However, because Sinotruk has released minor cab revisions over the years, we recommend confirming your chassis number or sending a photo of your current fairing before ordering. Our team will verify compatibility within 24 hours.

What material are these HOWO side fairings made from?

They’re injection-molded from high-density polypropylene (PP) composite — the same class of material used in OEM production. This gives them excellent impact resistance, UV stability, and flexibility in extreme temperatures without cracking.

Can I order just one side fairing instead of the pair?

Yes. While we list them as a pair for better value and color-matched consistency, you can order the left (WG1664111051) or right (WG1664111052) side fairing individually. Simply specify your requirement when requesting a quote.

How are the side fairings packaged for international shipping?

Each pair is individually wrapped in protective foam, then placed inside a reinforced corrugated carton designed to prevent flexing or cracking during transit. For bulk orders, we palletize and strap shipments for container loading. Custom packaging is available for white-label customers.

Do these fairings require painting before installation?

Not necessarily. They arrive in a textured matte black finish that blends well with most HOWO cab configurations. However, if your fleet uses a specific color scheme, the PP surface accepts automotive paint after proper primer application. We also offer factory pre-painting upon request.

What is the typical lead time for a bulk side fairing order?

Standard stock orders ship within 3–5 business days. For large-volume or white-label orders requiring custom packaging, production and delivery typically take 15–25 days depending on quantity. We provide real-time tracking once your shipment departs.
