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 rolled eyelet at one end for chassis connection and a tapered profile at the other, designed to integrate with adjacent leaf plates in the suspension stack.

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 2902202-80A FAW – OEM Quality Suspension Component

When your FAW truck hits the road, every bump and pothole tests the limits of your suspension system.

Key Features and Benefits of the 2902202-80A Leaf Spring

Choosing the right leaf spring isn’t just about fit — it’s about long-term reliability, safety, and total cost of ownership. Here’s what makes this single plate stand out:

• Precise OEM Compatibility: Manufactured to match the original FAW part number 2902202-80A, ensuring a direct bolt-on fitment without modifications.
• High-Strength Spring Steel: Crafted from heat-treated alloy spring steel that resists fatigue cracking, sagging, and premature failure under heavy cyclic loads.
• Superior Load Distribution: The single-plate design efficiently distributes weight across the front axle, maintaining ride height and steering geometry even under full payload.
• Vibration Dampening: Engineered curvature and temper characteristics absorb road shocks and vibrations, protecting the chassis frame, cab, and cargo from excessive stress.
• Corrosion-Resistant Finish: Shot-peened surface and protective coating extend service life in humid, dusty, or salt-laden operating environments.
• Factory-Direct Pricing: By sourcing directly from Mettlead, you eliminate intermediary markups while still receiving strict quality-controlled components.

Below you’ll find the critical parameters for this FAW leaf spring single plate. These specifications help ensure you’re ordering the correct part for your specific truck model and application:

Application Scenarios and Compatible Models

This Leaf Spring Single Plate 2902202-80A is specifically designed for FAW front axle suspension systems. It serves as the primary load-carrying and shock-absorbing element in the front leaf spring assembly, and you’ll typically find it at work in these scenarios:

• Long-Haul Freight Transport: Maintains consistent front axle ride height and steering precision over thousands of kilometers, even when the truck navigates poorly maintained highways.
• Construction and Mining Haulage: Withstands repeated high-amplitude impacts from unpaved roads and job-site terrain without cracking or deforming.
• Urban Distribution Fleets: Absorbs constant stop-and-go vibrations in city driving, reducing driver fatigue and protecting sensitive cargo.
• Mixed-Fleet Maintenance Programs: A direct replacement part that procurement teams can stock in bulk to minimize vehicle downtime across multiple FAW trucks.

If you’re managing a fleet of FAW heavy-duty or medium-duty trucks, this leaf spring keeps your front suspension performing as the factory intended — no guesswork, no adaptation, just reliable function.

Frequently Asked Questions

What is the function of a single leaf spring plate in a truck suspension?

A single leaf spring plate acts as both a structural load-bearing element and a shock absorber. In the front axle assembly, it supports the weight of the cab and engine while flexing to absorb road irregularities. This keeps the truck’s ride stable, protects the frame from stress fractures, and maintains proper wheel alignment under varying loads.

How do I confirm that part number 2902202-80A fits my FAW truck?

The most reliable method is to cross-reference the OEM part number stamped on your existing leaf spring or listed in your truck’s parts manual. Part number 2902202-80A corresponds to the front single leaf spring plate for specific FAW models. If you’re unsure, send us your vehicle identification number (VIN) or chassis number, and our technical team will verify compatibility for you.

What causes a leaf spring to fail, and how can I extend its service life?

Most leaf spring failures stem from metal fatigue caused by repeated overloading, corrosion from road salt or moisture, or stress fractures initiated by surface imperfections. To maximize lifespan, avoid consistently exceeding rated payload, inspect spring eyes and center bolts during routine maintenance, and replace corroded U-bolts or worn rubber bushings promptly. Catching small issues early prevents cascading damage to the entire suspension assembly.

Can I order this leaf spring with custom specifications or modified dimensions?

Yes. If your application requires a non-standard thickness, camber, or eye diameter, our engineering team can evaluate the feasibility of producing a modified version. Simply provide your desired specifications along with the intended application, and we’ll respond with a technical proposal and quotation.

What quality assurance measures does Mettlead apply to leaf spring production?

Each leaf spring plate undergoes a multi-stage inspection process: raw material certification, hardness testing after heat treatment, dimensional verification against OEM drawings, surface defect inspection post-shot-peening, and final packaging audit. These layered checks ensure that every piece leaving our facility meets the fatigue resistance and load capacity standards your trucks require.
