Product Introduction

Structure

This front suspension shock absorber upper left bracket adopts an integrated precision casting process with high-strength alloy cast steel as the base material. It features an asymmetric structural design, integrating a flat mounting plate with multiple precision-drilled bolt holes and a reinforced shock absorber pivot seat. The surface is coated with a high-temperature resistant black anti-corrosion finish, and the key mounting surfaces and pivot holes are precision-machined to ensure zero clearance matching.

Performance

Crafted from premium alloy cast steel and treated with quenching and tempering, the bracket achieves high structural rigidity and impact toughness, capable of withstanding the continuous alternating loads generated by the shock absorber during heavy-duty vehicle operation. The anti-corrosion coating has excellent resistance to gravel impact, salt spray erosion and high temperature aging, maintaining stable mechanical properties in the temperature range of -40°C to 150°C.

Core Function

1. Serves as the exclusive upper mounting carrier for the left front suspension shock absorber, providing a fixed and pivotable connection point for the shock absorber to realize the normal telescopic damping movement.

2. Transmits the damping reaction force generated by the shock absorber to the vehicle frame/cab suspension crossbeam, and disperses the concentrated load to avoid local structural fatigue damage.

3. Ensures the precise spatial angle of the shock absorber, maintains the optimal matching state between the shock absorber and the suspension system, and guarantees the stability of the vehicle’s front suspension damping performance.

Front Suspension Shock Absorber Upper Left Bracket 810W41720-0147 – Sinotruk Sitrak Genuine Replacement Part

When your Sitrak truck’s front suspension starts showing signs of wear, a failing shock absorber bracket is often the hidden culprit. The Front Suspension Shock Absorber Upper Left Bracket (OEM: 810W41720-0147) plays a critical role in securing the shock absorber to the chassis, ensuring stable damping performance and driver comfort. Designed specifically for Sinotruk Sitrak heavy-duty trucks, this bracket withstands continuous road vibrations and heavy payloads without compromise. At Mettlead, we supply this part directly from the factory floor — giving you access to competitive pricing, reliable quality, and fast global shipping that keeps your fleet moving.

Key Features and Benefits of the 810W41720-0147 Upper Left Bracket

Choosing the right suspension bracket isn’t just about fitment — it’s about long-term reliability and reduced maintenance costs. Here’s why this particular component stands out:

• Precision OEM Fitment: Engineered to match original Sinotruk Sitrak specifications, this bracket drops right into position without any modifications, saving your workshop valuable time.
• High-Strength Construction: Manufactured from premium-grade steel with reinforced stress points, it resists fatigue cracking even under continuous heavy-load conditions.
• Corrosion-Resistant Surface Treatment: A protective coating shields the bracket against road salt, moisture, and chemical exposure — extending its service life significantly.
• Optimal Shock Absorber Anchoring: The bracket provides a stable, vibration-dampening mounting point for the front shock absorber, directly contributing to improved ride quality and tire longevity.
• Factory-Direct Pricing: Because Mettlead sources directly from certified production lines in China, you receive genuine-quality parts at wholesale pricing without middleman markups.

In other words, this bracket doesn’t just hold your shock absorber in place — it actively protects your entire front suspension system from premature wear.

Application Scenario: Where Does the 810W41720-0147 Bracket Fit?

Understanding exactly where and how this part functions helps you make a confident purchasing decision. So let’s break it down:

Compatible Vehicle Models

This upper left bracket is specifically designed to fit Sinotruk Sitrak series heavy-duty trucks, including the C7H and G7 models equipped with standard front suspension configurations. If your Sitrak truck uses the original 810W41720-0147 part number, this is your direct replacement.

Mounting Position and Function

Located on the upper left side of the front axle suspension assembly, this bracket serves as the primary anchor point for the front shock absorber. It securely fastens the top of the shock absorber to the truck’s frame rail, ensuring that damping forces are transferred efficiently into the chassis structure. Without a properly functioning upper bracket, the shock absorber cannot maintain consistent contact pressure — leading to excessive bouncing, uneven tire wear, and compromised steering stability.

Frequently Asked Questions About the 810W41720-0147 Upper Left Bracket

What symptoms indicate that this bracket needs replacement?

Over time, you may notice clunking or metallic rattling noises coming from the front suspension — particularly when driving over bumps or rough terrain. Visible cracks, elongated bolt holes, or heavy rust on the bracket are also clear signs that replacement is overdue. If your shock absorber appears loose or tilted, the bracket is almost certainly compromised.

Can I install this bracket without replacing the shock absorber itself?

Yes, absolutely. If your shock absorber is still in good working condition and only the bracket shows damage or fatigue, you can replace the bracket independently. However, it’s wise to inspect the shock absorber’s bushings and mounting hardware at the same time, since worn bushings can accelerate bracket wear.

Is the 810W41720-0147 bracket interchangeable with the right-side bracket?

No, it is not. The upper left bracket (810W41720-0147) is designed specifically for the left-hand mounting position. The geometry, bolt hole orientation, and clearance angles differ from the right-side counterpart. Always order based on the correct OEM part number to ensure proper fitment.

What torque specifications should be used when installing this bracket?

We recommend following the Sinotruk Sitrak workshop manual torque values for front suspension components. Generally, upper shock absorber bracket bolts require a torque between 80–120 Nm depending on the specific model variant. Always use calibrated tools and verify against the official service documentation for your truck.

How does road salt or harsh weather affect this bracket’s lifespan?

While the anti-corrosion coating provides substantial protection, prolonged exposure to road salt, coastal humidity, or chemical de-icing agents will gradually degrade any surface treatment. For trucks operating in harsh climates, periodic inspection every 30,000–50,000 km is recommended. Applying additional rust-preventive spray during routine maintenance can further extend service life.
