Product Introduction

This shock absorber is a hydraulic damping component with an integrated coil spring, designed for heavy-duty truck suspension systems. It features a cylindrical steel body with a dark gray anti-corrosion coating, an integrated helical coil spring, and both ends are fitted with metal bushings for pivot connection. The body is marked with specifications and a QR code for easy identification and traceability.

Performance

Manufactured with precision-machined components and high-quality hydraulic fluid, this shock absorber delivers consistent damping performance, vibration isolation, and impact absorption. It operates reliably in temperatures ranging from -40°C to 120°C, resisting degradation from road contaminants and harsh operating conditions. The integrated coil spring provides additional load support and progressive stiffness, effectively controlling suspension movement and improving ride stability.

Core Function

1. Serves as a critical damping and load-supporting component in the suspension system, absorbing and dissipating road impacts and vibrations to ensure a smooth, stable ride.

2. Controls excessive suspension movement, preventing wheel hop and maintaining tire contact with the road surface for improved handling and safety.

3. Reduces stress on chassis and suspension components, extending their service life by minimizing fatigue and wear.

4. Enhances overall vehicle stability and control, especially under heavy loads or during cornering, braking, and acceleration.

Shock Absorber WG1642440088 Sinotruk – Heavy-Duty Truck Suspension Damper

When your heavy-duty truck hits rough terrain day after day, a reliable shock absorber isn’t just a component — it’s the backbone of ride stability and cargo safety. The Shock Absorber WG1642440088 Sinotruk is a precision-engineered hydraulic damping unit built specifically for SINOTRUK HOWO heavy truck suspension systems. Manufactured with strict quality control and supplied directly from our factory in China, this shock absorber delivers consistent damping performance, extended service life, and seamless fitment — all at a competitive wholesale price that keeps your procurement budget in check.

At Mettlead, we understand that procurement managers need more than just a part number — you need confidence in quality, accuracy in specifications, and reliability in delivery. That’s exactly what we deliver with every order. Whether you’re sourcing for fleet maintenance, aftermarket distribution, or workshop repair, this Sinotruk shock absorber is ready to perform.

Key Features and Benefits of Shock Absorber WG1642440088

Superior Hydraulic Damping Performance

This shock absorber utilizes a twin-tube hydraulic damping mechanism that effectively absorbs road vibrations and impacts. As a result, it minimizes vertical oscillation and ensures stable handling even under heavy payloads, which ultimately protects both the driver and the cargo.

Integrated Helical Coil Spring Design

Unlike standalone dampers, the WG1642440088 features an integrated coil spring that works in harmony with the hydraulic cylinder. This combined design simplifies installation, reduces the number of separate components needed, and provides a balanced suspension response across varying load conditions.

Heavy-Duty Anti-Corrosion Coating

The cylindrical steel body is treated with a dark gray anti-corrosion coating that resists rust, road salt, and chemical exposure. Consequently, this protective layer significantly extends the component’s lifespan — even in harsh operating environments such as mining sites, construction zones, and tropical climates.

Precision Metal Bushings for Secure Mounting

Both ends of the shock absorber are fitted with high-strength metal bushings designed for pivot connection. These bushings ensure a tight, rattle-free fit to the chassis mounting points, which eliminates play and reduces premature wear on adjacent suspension components.

QR Code Traceability

Each unit is marked with specifications and a scannable QR code directly on the body. This feature allows you to quickly verify authenticity, trace the production batch, and access technical data — giving you full transparency and peace of mind in your supply chain.

Factory-Direct Pricing Advantage

By sourcing directly from Mettlead, you eliminate middlemen and enjoy genuine factory pricing. Moreover, our flexible and secure payment methods, combined with fast global shipping, mean your parts arrive on time without unnecessary cost markups.

Frequently Asked Questions – Shock Absorber WG1642440088 Sinotruk

What trucks does the Shock Absorber WG1642440088 fit?

This shock absorber is specifically designed for SINOTRUK HOWO heavy-duty truck models that use the WG1642440088 part number in their chassis suspension system. Before ordering, we recommend verifying the OEM part number against your truck’s maintenance manual or VIN-based parts catalog to ensure exact compatibility.

How can I tell if my truck’s shock absorber needs replacement?

Several signs indicate a failing shock absorber: excessive bouncing after hitting bumps, visible oil leakage on the damper body, uneven tire wear patterns, increased braking distance, or a noticeable nose-dive when stopping. Additionally, if the coil spring shows cracks or deformation, the entire assembly should be replaced immediately for safety reasons.

Is this an OEM original part or an aftermarket replacement?

The WG1642440088 shock absorber supplied by Mettlead is a high-quality aftermarket replacement manufactured to OEM specifications. It matches the original part in dimensions, damping characteristics, and mounting configuration — ensuring direct bolt-on fitment without modifications.

What is the expected service life of this shock absorber?

Under normal operating conditions, this shock absorber typically delivers reliable performance for 80,000–120,000 kilometers. However, actual lifespan depends on factors such as road conditions, payload frequency, driving habits, and environmental exposure. Regular inspection during scheduled maintenance helps identify early signs of wear.

Can I order this shock absorber with custom branding or packaging?

Absolutely. Mettlead offers white-label and custom packaging services for the WG1642440088 and all other parts in our catalog. Simply provide your branding requirements — including logos, color schemes, and packaging dimensions — and our team will prepare samples for your approval before bulk production.

How should I store this shock absorber before installation?

Store the shock absorber in its original packaging in a dry, cool environment away from direct sunlight and moisture. Keep it in a vertical or horizontal position without heavy objects stacked on top. Avoid exposing the unit to corrosive chemicals or extreme temperatures, as these can degrade the hydraulic seals and coating over time.
