Front Suspension Spring Shock Absorber (Part No. H4502A01030A0)

Product Introduction

Structure

This front leaf spring single plate is a precision-formed flat component made of high-strength spring steel with a black anti-corrosion finish. It has rolled eyelets at both ends for chassis and shackle connection, and is precision-machined for uniform thickness and flatness.

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 primary vertical load support for the front axle, absorbing road shocks and maintaining the designed ride height of the vehicle’s front end.

2. Works with other leaf spring plates to form a flexible suspension system, allowing controlled wheel travel over uneven terrain.

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

4. Serves as a key front suspension component, complementing shock absorbers and stabilizer bars to enhance ride comfort and handling performance.

Key Features and Benefits of the 2902201-71A Front Leaf Spring Single Plate

This front leaf spring single plate doesn’t just sit under the axle — it actively works to protect the truck’s frame, cargo, and driver comfort. Here’s why distributors and fleet managers choose this part with confidence:

• Precise OEM Fitment: Manufactured to match FAW original part number 2902201-71A dimensions and tolerances, ensuring hassle-free installation without modifications.
• High-Strength Spring Steel: Forged from premium alloy spring steel that resists fatigue cracking, sagging, and permanent deformation even under sustained heavy loads.
• Superior Shock Absorption: The single-plate design effectively cushions road surface impacts, protecting the front axle assembly and extending the service life of surrounding suspension components.
• Corrosion-Resistant Finish: Surface-treated to withstand harsh weather, salt spray, and mud exposure — particularly important for trucks operating in tropical or coastal regions.
• Wholesale-Friendly Pricing: Factory-direct supply from China eliminates middlemen, giving you more room to compete in your local market.
• Flexible MOQ: We accommodate both trial orders and large container shipments, adapting to your business cycle.

In other words, this leaf spring single plate works hard so your customers’ trucks don’t have to work harder than necessary. And for you as a reseller, that translates into fewer warranty claims and more repeat orders.

Application Scenarios – Where Does This Front Leaf Spring Fit?

The Front Leaf Spring Single Plate 2902201-71A is specifically designed for FAW heavy-duty and medium-duty truck models equipped with front leaf spring suspension systems. Its primary roles include:

• Bearing Front Axle Load: It supports the weight distributed to the front axle, maintaining proper ride height and steering geometry under loaded conditions.
• Buffering Road Impact: On rough terrain, unpaved roads, or pothole-ridden highways, this plate absorbs vertical shocks before they reach the chassis frame.
• Maintaining Axle Alignment: By resisting lateral and longitudinal forces, it keeps the front axle properly located, preserving tire wear patterns and handling stability.

Typical vehicle applications include FAW J6, J7, and Jiefang series trucks used in long-haul logistics, construction material transport, and mining operations. If you serve markets in Africa, Southeast Asia, the Middle East, or Central Asia where FAW trucks are widely deployed, this part belongs in your inventory.

Frequently Asked Questions About Front Leaf Spring Single Plate 2902201-71A

What causes a front leaf spring single plate to fail?

Over time, constant load cycling and road impacts cause metal fatigue in the spring steel. Additionally, corrosion from road salt, moisture, and chemical exposure weakens the material structure. You’ll typically notice sagging ride height, uneven tire wear, or visible cracks on the plate surface before complete failure occurs.

How can I tell if the front leaf spring single plate needs replacement?

Look for these warning signs: the truck nose sits lower than normal, the steering pulls to one side under load, you hear metallic clunking over bumps, or you can visually spot fractures or permanent bending in the plate. Replacing early prevents costly damage to the front axle, king pins, and steering linkage.

Is the 2902201-71A front leaf spring plate a direct bolt-on replacement?

Yes. This part is manufactured to OEM dimensions, so it bolts directly onto the original spring pack mounting points without any drilling, welding, or adapter brackets. However, we always recommend confirming your exact truck model and year before ordering to guarantee perfect fitment.

Should I replace only one plate or the entire leaf spring assembly?

If only the single plate is cracked or sagged and the remaining leaves in the pack are in good condition, replacing just this plate is cost-effective and practical. However, if multiple plates show wear, replacing the complete assembly ensures balanced performance and avoids premature re-failure.

What material is used, and how does it affect durability?

This front leaf spring single plate is typically made from 60Si2Mn or equivalent high-strength alloy spring steel. This material offers excellent elastic recovery, high fatigue resistance, and good hardness — meaning the plate flexes repeatedly without taking a permanent set, even under heavy payloads.

Can this leaf spring plate handle overloaded conditions?

While the plate is engineered to support rated front axle loads, consistent overloading accelerates fatigue and shortens service life. For markets where trucks routinely carry above-rated weight, we recommend discussing reinforced or thicker plate options with our team.
