Product Introduction

Structure

This spring pin is a precision-machined alloy steel component, featuring a stepped cylindrical design with a smooth main body, a threaded end for nut retention, and a hexagonal nut for secure clamping. It is equipped with a high-durometer rubber seal to prevent corrosion and wear at the interface with the leaf spring assembly. The surface is precision-ground to ensure a tight fit and optimal load distribution.

Performance

Forged from high-strength alloy steel and heat-treated for maximum toughness, it withstands extreme shear forces and repeated impact loads inherent in heavy-duty suspension systems. The rubber seal provides reliable protection against rust, salt spray, and chemical corrosion, ensuring consistent performance in temperatures ranging from -40°C to 120°C.

Core Function

1. Serves as the primary pivot and clamping component for the leaf spring assembly, securing the spring stack to the hanger or shackle while allowing controlled articulation.

2. Transmits shear and impact loads from the leaf spring to the chassis, distributing forces evenly to prevent structural damage and premature wear.

3. Maintains precise alignment of the leaf spring assembly, ensuring consistent spring rate and performance during operation.

4. Resists loosening under sustained vibration and heavy impacts, preventing premature failure of the leaf spring system and ensuring safe and reliable operation of heavy-duty trucks.

Spring Pin DZ9114520005 SHACMAN – Premium Chassis Fastener for Heavy-Duty Trucks

When your SHACMAN truck’s suspension system demands reliable fastening, every component matters. The Spring Pin DZ9114520005 is a critical chassis connector that keeps your leaf spring assembly secure, stable, and road-ready. Engineered to meet OEM specifications, this genuine-equivalent spring pin delivers the durability and precision that fleet operators and maintenance teams depend on daily. At Mettlead, we supply this part directly from our factory network in China, which means you get authentic quality at a competitive price — without the middleman markup.

Why This SHACMAN Spring Pin DZ9114520005 Stands Out

A spring pin might seem like a small detail, but it plays a big role in your truck’s ride quality and structural integrity. Here’s what makes this particular part a smart investment for your fleet:

• OEM-Grade Precision: Manufactured to match the exact dimensions and tolerances of the original DZ9114520005 specification, ensuring a perfect fit every time.
• High-Strength Material: Forged from premium alloy steel with appropriate heat treatment, this pin resists shearing forces, fatigue cracking, and corrosion — even under heavy payloads.
• Extended Service Life: Thanks to its hardened surface finish, the pin withstands repetitive stress cycles far longer than generic aftermarket alternatives.
• Reduced Downtime: A direct-fit replacement means your mechanics spend less time on installation and more time getting trucks back on the road.
• Cost-Effective Maintenance: Factory-direct pricing from Mettlead keeps your per-unit cost low, especially on bulk orders for fleet-wide maintenance schedules.

Application & Compatible Vehicles

The Spring Pin DZ9114520005 is specifically designed for the leaf spring suspension system found in SHACMAN (陕汽) heavy-duty trucks. It serves as the pivot connection between the leaf spring eye and the spring bracket on the chassis frame, absorbing road shock and maintaining axle alignment under load.

Fitment Guide

• SHACMAN F2000 series trucks
• SHACMAN F3000 series trucks
• SHACMAN Delong (德龙) series
• Other SHACMAN models using the DZ9114520005 spring pin specification

This spring pin is commonly replaced during routine suspension overhauls, leaf spring replacements, or when play is detected in the spring eye bushing area. If you’re sourcing parts for other SHACMAN truck components, we carry a comprehensive catalog to match your needs.

Frequently Asked Questions

What exactly does the Spring Pin DZ9114520005 do in the suspension system?

This spring pin acts as the pivot shaft that connects the leaf spring eye to the fixed bracket on the truck’s chassis frame. In other words, it’s the hinge point that allows the leaf spring to flex and absorb road impacts while keeping the axle properly aligned. Without a properly functioning spring pin, you’ll notice excessive play, uneven tire wear, and compromised ride stability.

How do I know when this spring pin needs replacement?

Common signs include clunking or knocking noises from the suspension area, visible wear or scoring on the pin surface, looseness in the leaf spring eye, or uneven gaps between the spring and bracket. During routine inspections, mechanics should check for lateral play — if the pin moves more than the specified tolerance, it’s time for a swap.

Is this an original SHACMAN part or an aftermarket replacement?

This is an OEM-equivalent aftermarket part manufactured to the same dimensional and material specifications as the original DZ9114520005. It fits and performs identically to the factory-installed pin, and it passes the same hardness and dimensional standards required by the OEM drawing.

Can I order this spring pin in bulk for fleet maintenance?

Absolutely. Mettlead specializes in bulk supply for fleet operators and distributors. We offer volume-based pricing, and our stock levels are maintained to support large orders with short lead times. Simply let us know your quantity requirements and preferred delivery schedule.

What’s the typical lead time for shipping?

For in-stock items, we typically ship within 3–5 business days. Larger custom orders or white-label packaging requests may require 7–15 days for preparation. We ship globally via sea freight, air freight, or express courier depending on urgency and order size.

Does the surface treatment affect longevity in humid or coastal climates?

Yes, positively. The zinc-plated or blackened finish provides a protective barrier against moisture, salt spray, and road chemicals. For trucks operating in particularly harsh environments — coastal regions, mining sites, or tropical climates — this corrosion resistance significantly extends the pin’s usable life compared to untreated alternatives.
