Product Introduction

Structure

This leaf spring single plate is a precision-formed, curved component made of high-strength spring steel with a black anti-corrosion finish. It features a precision-drilled mounting hole for integration with adjacent leaf plates and suspension hardware, and is precision-machined to maintain uniform thickness and curvature.

Performance

It withstands repeated flexing and heavy vertical loads, delivering consistent spring rate and fatigue resistance. The spring steel ensures reliable performance from -40°C to 120°C, with a service life tailored for heavy-duty truck operation.

Core Function

1. Provides secondary vertical load support within the leaf spring stack, working with the main leaf to absorb road shocks and distribute loads evenly across the suspension.

2. Contributes to the overall flexibility of the leaf spring assembly, allowing controlled wheel travel over uneven terrain while maintaining the vehicle’s ride height.

3. Transmits lateral and longitudinal forces from the axle to the chassis, enhancing vehicle stability during acceleration, braking, and cornering.

4. Serves as a key component in the leaf spring system, complementing shock absorbers and stabilizer bars to improve ride comfort and handling performance.

Leaf Spring Single Plate DZ9114520240-1 SHACMAN – Heavy-Duty Suspension Component for Reliable Load Support

When your SHACMAN truck faces punishing road conditions day after day, every suspension component needs to pull its weight. The Leaf Spring Single Plate DZ9114520240-1 is engineered to do exactly that — absorbing harsh vibrations, supporting heavy payloads, and keeping your chassis stable mile after mile. Sourced directly from our China-based factory, this single-plate leaf spring delivers OEM-grade performance at a price point that makes your procurement budget work harder. Whether you are managing a fleet or sourcing replacement parts for aftermarket distribution, Mettlead puts reliable quality and competitive pricing in your hands.

Key Features and Benefits of the DZ9114520240-1 Leaf Spring Single Plate

This isn’t just a piece of spring steel — it’s a precision-manufactured suspension element designed to meet the demanding operating conditions of SHACMAN heavy-duty trucks. Here’s what sets it apart:

• Superior Load-Bearing Capacity: Crafted from high-strength alloy spring steel, the DZ9114520240-1 leaf spring confidently handles heavy axle loads without premature fatigue or permanent deformation.
• Effective Vibration Dampening: The single-plate design provides progressive cushioning, smoothing out road shocks and reducing stress transferred to the chassis frame and cargo.
• Extended Service Life: Shot-peened surfaces and heat-treated construction resist cracking and corrosion, ensuring consistent performance across hundreds of thousands of kilometers.
• Precise OEM Fitment: Manufactured to match original SHACMAN specifications, so installation is straightforward with no modifications required.
• Factory-Direct Cost Advantage: By eliminating middlemen, Mettlead delivers this leaf spring at a price that strengthens your margin without compromising quality.

Application Scenarios

The Leaf Spring Single Plate DZ9114520240-1 is specifically designed for the SHACMAN truck suspension system. In real-world operation, it plays two critical roles simultaneously:

1. Chassis Load Support: Acting as a structural bridge between the axle and the frame, this leaf spring bears the static and dynamic weight of the vehicle body and payload. It distributes forces evenly across the mounting points, protecting the chassis from concentrated stress.
2. Ride Vibration Buffering: As the truck travels over uneven terrain, potholes, or rough construction sites, the leaf spring flexes to absorb vertical shocks. This protects both the driver and the cargo from excessive vibration, while also reducing wear on adjacent suspension and frame components.

Compatible Vehicle Models: SHACMAN (Shaanxi Automobile) heavy-duty truck series including F2000, F3000, X3000, and related models utilizing the DZ9114520240-1 part number in their rear or front suspension assemblies. For exact cross-reference confirmation, feel free to contact us with your VIN or chassis number.

Frequently Asked Questions

What causes a leaf spring single plate to fail prematurely?

Several factors can shorten the life of your DZ9114520240-1 leaf spring. Persistent overloading beyond rated capacity creates excessive stress that leads to micro-cracks over time. Additionally, corrosion from road salts or moisture can weaken the steel surface, while misaligned U-bolts or worn bushings allow abnormal movement that accelerates fatigue. Regular inspection of the spring surface for cracks and checking torque on mounting hardware helps catch problems early.

How can I tell if the DZ9114520240-1 leaf spring needs replacement?

Watch for visible signs such as cracks, fractures, or noticeable flattening of the spring arc. If the truck leans to one side under load, or you observe uneven tire wear on the affected axle, the leaf spring may have lost its designed camber. A sagging chassis height on one side compared to the other is another reliable indicator that the spring can no longer support its rated load.

Is this leaf spring an exact replacement for the original SHACMAN part?

Yes. The DZ9114520240-1 is manufactured to OEM dimensional and material specifications, meaning it fits directly into the existing suspension mounting points without any modification. The bolt pattern, eye dimensions, and arc geometry match the factory-installed component.

What material grade is used, and how does it handle fatigue?

This single plate leaf spring is manufactured from high-strength alloy spring steel — typically 60Si2Mn or an equivalent grade — then quenched and tempered to achieve optimal hardness and elasticity. The shot peening process introduces compressive residual stress on the surface, which significantly delays crack initiation under cyclic loading conditions.

Can I order a small trial quantity before committing to bulk?

Absolutely. We encourage new customers to start with a sample or small trial order to verify fitment and quality in their specific application before scaling up. Simply reach out through our inquiry form to discuss sample terms.
