Product Introduction

This heavy-duty steering arm is a critical component of the truck’s steering system, designed to efficiently transfer the rotational force from the steering gearbox to the right front wheel knuckle. Its robust construction ensures reliable performance under heavy loads and rough road conditions.

Structure & Material

• Material: High-strength forged steel, heat-treated for exceptional tensile strength, impact resistance, and fatigue durability.

Performance

• Precise Force Transfer: The optimized leverage and geometry ensure that steering input is translated accurately to the wheel, providing responsive and predictable control.

• Load Handling: The forged steel construction can withstand the high mechanical stresses generated during heavy-duty operation and off-road use.

• Smooth Articulation: Precision-machined bushings reduce friction and wear, ensuring smooth movement of the steering linkage.

Core Function

1. Force Transfer: Transmits steering force from the steering gearbox to the right front wheel knuckle.

2. Steering Control: Determines the steering geometry and leverage, ensuring precise and responsive wheel control.

3. Load Bearing: Supports the mechanical loads generated during steering maneuvers.

Steering Arm R AZ4071415052 – Sinotruk Sitrak Genuine Replacement Part

When your Sinotruk Sitrak heavy-duty truck needs a reliable right steering arm, the Steering Arm R AZ4071415052 delivers the precise steering force transmission your front axle demands. Engineered to OEM specifications, this critical steering component ensures your wheels respond accurately to every driver input — keeping your fleet safe, efficient, and on the road. At Mettlead, we supply this part directly from the factory, which means you get genuine quality at a competitive price without the middleman markup.

Application Scenario: Where This Steering Arm Performs

The Steering Arm R AZ4071415052 is specifically designed for the Sinotruk Sitrak series of heavy-duty trucks. Installed on the right side of the front axle assembly, this steering arm plays a vital role in your truck’s steering system. It receives rotational force from the steering gear and transmits that power to the steering knuckle, ultimately controlling the directional movement of the right front wheel.

In other words, every time the driver turns the steering wheel, this component translates that intention into precise wheel movement. Without a properly functioning right steering arm, steering response becomes sluggish, uneven tire wear accelerates, and — in worst-case scenarios — vehicle control is compromised. That’s why replacing a worn or damaged steering arm promptly is not just a maintenance decision; it’s a safety imperative.

This part is ideal for fleet operators, repair workshops, and distributors who service Sitrak trucks across long-haul logistics, construction haulage, and heavy transport applications. You can explore more compatible components on our Sitrak Heavy-Duty Parts brand page.

Frequently Asked Questions (FAQ)

What is the function of Steering Arm R AZ4071415052 in a Sitrak truck?

The right steering arm acts as the mechanical link between the steering drag link and the right steering knuckle. When the driver turns the wheel, steering force travels through the gear box, into the drag link, and then into this arm — which pivots the knuckle and turns the right front wheel. Essentially, it’s the final lever that makes your wheel obey the steering wheel.

How do I know if my right steering arm needs replacement?

Common signs include uneven or excessive tire wear on the right front wheel, a noticeable pull to one side during driving, loose or vague steering feel, and visible cracks or deformation on the arm itself. If you notice clunking noises from the front axle during turns, the steering arm’s mounting points may be worn. A qualified technician should inspect the component during routine front axle maintenance.

Is this steering arm an exact OEM replacement for Sinotruk Sitrak trucks?

Yes. The AZ4071415052 part number corresponds directly to the original Sinotruk specification. It matches the OEM dimensions, mounting hole pattern, and material grade, so it bolts on without any modification or adapter required.

What material is the Steering Arm R AZ4071415052 made from?

This steering arm is manufactured from high-strength forged steel that undergoes heat treatment for optimal hardness and fatigue resistance. The forging process aligns the steel’s grain structure along the arm’s load path, which significantly improves durability compared to cast alternatives.
