Product Introduction

Structure

This rear leaf spring single plate is a precision-formed flat component made of high-strength spring steel with a black anti-corrosion finish. It features a uniform 25x90mm cross-section and precision-machined edges, designed to integrate seamlessly into the rear leaf spring 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 primary vertical load support for the rear axle, absorbing road shocks and maintaining the designed ride height of the vehicle’s rear end under heavy loads.

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

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

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

Key Features and Benefits of the 2912201-483 Rear Leaf Spring

This FAW rear leaf spring single plate is more than just a strip of steel — it’s the backbone of your truck’s rear suspension system. Here’s what sets it apart:

• OEM-Matched Specification: Manufactured to match FAW original part number 2912201-483, ensuring a precise fit without modification.
• High-Strength Spring Steel: Crafted from premium alloy spring steel that resists fatigue, sagging, and premature cracking — even under continuous heavy loading.
• Optimized Load Distribution: The single-plate design efficiently distributes rear axle loads across the suspension, protecting the chassis and extending component life.
• Superior Shock Absorption: Engineered curvature and temper effectively cushion road impacts, reducing vibration transferred to the frame and cargo.
• Corrosion-Resistant Finish: Surface treatment guards against rust and environmental degradation, prolonging service life in harsh operating conditions.
• Drop-In Installation: Bolt-on replacement design means faster turnaround in the workshop, minimizing vehicle downtime.

In other words, this component works quietly behind the scenes — absorbing punishment so the rest of your truck doesn’t have to.

Application Scenario: Where This Rear Leaf Spring Single Plate Performs

The 2912201-483 FAW Rear Leaf Spring Single Plate is specifically designed for FAW heavy-duty and medium-duty truck models equipped with a single-plate rear leaf spring suspension configuration. Its primary role is to:

• Bear the rear axle load — supporting the full weight of cargo transmitted through the rear axle to the chassis frame.
• Buffer road surface impacts — absorbing vibrations from uneven terrain, potholes, and sudden bumps before they reach the truck body and freight.
• Maintain axle alignment — keeping the rear axle properly positioned relative to the chassis during acceleration, braking, and cornering.

Consequently, this part is ideal for long-haul logistics trucks, construction-site dump trucks, and regional delivery vehicles that operate under heavy payloads and demanding road conditions. Fleet operators who replace worn or cracked leaf springs promptly prevent cascading damage to U-bolts, shackles, spring hangers, and even the frame rails themselves.

Frequently Asked Questions (FAQ)

What does the part number 2912201-483 correspond to?

Part number 2912201-483 is the OEM reference for the rear leaf spring single plate used in certain FAW truck models. It identifies the specific spring dimensions, curvature, and load rating designed by the original manufacturer for the rear suspension system.

How do I know if this rear leaf spring fits my FAW truck?

First, confirm your vehicle’s original part number on the existing spring or in the FAW parts manual. If it matches 2912201-483, this is a direct replacement. If you’re unsure, send us your truck model, year, and VIN — our team will cross-reference compatibility for you.

What are the signs that my rear leaf spring needs replacement?

Watch for visible cracks or fractures in the spring plate, excessive rear sag (the truck sits lower than normal at the rear), uneven tire wear on the rear axle, or clunking noises over bumps. Additionally, if your loaded truck bottoms out more easily than before, the spring has likely lost its designed camber and load capacity.

Is this a single leaf or part of a multi-leaf spring pack?

This listing is for a single plate — one individual leaf. Depending on your truck’s suspension configuration, it may function as a standalone parabolic spring or serve as a replacement leaf within a multi-leaf assembly. Confirm your specific setup before ordering.

What material is used, and how long will it last?

The spring is manufactured from high-strength alloy spring steel (typically 60Si2Mn grade), then shot-peened and coated for corrosion resistance. Under normal operating conditions and proper load management, you can expect service life comparable to OEM original parts — often exceeding 200,000 km before inspection is recommended.

Can I order just one piece, or is there a minimum order quantity?

We cater primarily to B2B buyers, so MOQ may apply. However, we understand that sometimes you need a single piece urgently. Contact us with your quantity needs, and we’ll do our best to accommodate.
