Product Introduction

This precision-machined synchronizer ring is a key friction element of the transmission’s gear shift system, designed to match the rotational speeds of the target gear and main shaft before engagement, ensuring smooth and precise gear changes.

• Structure & Material:

• Material: High-friction bronze alloy, precision-machined for optimal heat dissipation and friction performance.

• Design: A split-ring construction with external serrated teeth that mesh with the synchronizer sleeve, and an inner conical friction surface that interfaces with the target gear’s cone.

  • Performance:

• The high-friction bronze material generates controlled friction to equalize the rotational speed of the gear and shaft, eliminating gear clash during shifts.The serrated edge ensures positive engagement with the synchronizer sleeve, providing precise feedback during gear selection.

  • Durability: The bronze alloy construction withstands the high friction and heat of frequent gear changes, ensuring long service life under heavy-duty operating conditions.

Core Function

1. Speed Synchronization: Uses friction to match the rotational speed of the target gear and main shaft, preventing gear clash.

2. Clash Prevention: Ensures smooth, quiet gear changes by equalizing speeds before the dog teeth engage.

3. Positive Engagement: The serrated teeth lock into the synchronizer sleeve, providing precise feedback and secure gear holding.

Synchronizer Ring 1268304594 for ZF Gearbox – Premium Quality, Factory-Direct Pricing

When your fleet depends on smooth, reliable gear shifting, every component matters. The Synchronizer Ring 1268304594 is a precision-engineered transmission component designed specifically for ZF 9S1110 and 9S1310 gearboxes. At Mettlead, we supply this critical part directly from our factory in China, which means you get OEM-equivalent quality at a price that protects your profit margins. Whether you’re a wholesale distributor or a regional parts agent, this synchronizer ring delivers the performance and durability your customers expect.

Why This Synchronizer Ring 1268304594 Stands Out

A synchronizer ring might seem like a small component, but it plays a vital role in ensuring seamless gear engagement. Here’s what makes our ZF gearbox synchronizer ring a smart choice for your inventory:

• Precise Dimensional Accuracy – Manufactured to match OEM specifications, ensuring a perfect fit within ZF transmission assemblies without modification.
• High-Grade Material Composition – Crafted from wear-resistant alloy with optimized friction surfaces, this ring maintains consistent synchronization performance over extended service intervals.
• Smooth Gear Engagement – The engineered friction coating and cone geometry reduce shifting effort, minimize noise, and protect adjacent gearbox components from premature wear.
• Extended Service Life – Rigorous heat treatment and surface finishing processes ensure long-lasting durability even under heavy-duty commercial vehicle operating conditions.
• Wholesale-Friendly Pricing – As a factory-direct supplier, we eliminate middlemen, giving you competitive unit costs that enhance your resale margins.

Application Scenarios – Where This Synchronizer Ring Fits

The Synchronizer Ring 1268304594 is purpose-built for ZF manual transmissions commonly found in medium and heavy-duty commercial vehicles. Specifically, it is compatible with:

• ZF 9S1110 Gearbox – Widely used in SINOTRUK HOWO, Shacman, and other Chinese-brand heavy trucks.
• ZF 9S1310 Gearbox – Found in FAW, Dongfeng, and Foton trucks configured for long-haul and construction applications.
• ZF 9S-Series Variants – Compatible across multiple 9-speed synchronized transmission configurations using the 1268304594 reference number.

In daily operation, this synchronizer ring ensures that drivers experience effortless gear changes, whether navigating steep inclines with a loaded trailer or downshifting on congested highways. For fleet operators, that translates into fewer transmission complaints, reduced maintenance downtime, and longer intervals between overhauls.

Customer Case Study – Synchronizer Ring 1268304594 in Action

A truck parts distributor based in East Africa approached Mettlead seeking a reliable supply of ZF gearbox synchronizer rings for their growing HOWO aftermarket business. Their previous supplier delivered inconsistent quality, leading to frequent returns and damaged customer trust.

After switching to our Synchronizer Ring 1268304594, the results spoke for themselves. Over a 12-month period, the distributor reported a 95% reduction in warranty claims related to ZF transmission shifting issues. Furthermore, our factory-direct pricing allowed them to improve their per-unit margin by approximately 18%, while our white-label packaging helped them strengthen their own regional brand identity.

Today, they order regularly in bulk and have expanded their catalogue to include additional ZF gearbox components from our range.

Frequently Asked Questions – Synchronizer Ring 1268304594

What is the function of a synchronizer ring in a ZF gearbox?

A synchronizer ring equalizes the rotational speed between the gear and the transmission shaft during shifting. In simple terms, it acts as a friction brake that brings both components to the same speed so the gear can engage smoothly and quietly. Without a properly functioning synchronizer ring like the 1268304594, gear grinding, difficult shifting, and accelerated transmission wear occur.

How do I verify that the 1268304594 synchronizer ring fits my gearbox?

Cross-reference the OEM part number 1268304594 with your ZF gearbox model. This ring is designed for ZF 9S1110 and 9S1310 transmissions. If you’re unsure about compatibility, send us your gearbox nameplate photo or serial number and our technical team will confirm the match.

What causes a synchronizer ring to wear out?

Over time, the friction surface on the synchronizer ring gradually wears down due to repeated gear engagement. Contributing factors include aggressive shifting habits, insufficient gearbox oil, contaminated lubricant, or operating under extreme load conditions. When the friction material becomes too thin, the ring can no longer synchronize speeds effectively, resulting in notchy or grinding shifts.

How can I tell if the synchronizer ring 1268304594 needs replacement?

Common symptoms include difficulty engaging specific gears, a grinding or crunching noise during shifts, or the gear lever popping out of position. If a ZF 9S1110 or 9S1310 gearbox exhibits these signs, inspecting the synchronizer rings should be a first step during diagnosis.

Is this synchronizer ring an OEM original or aftermarket part?

This is a high-quality aftermarket replacement manufactured to OEM specifications. It is dimensionally identical to the original ZF part, uses equivalent-grade materials, and undergoes strict quality control testing to ensure performance parity with the factory component.

What is the minimum order quantity for wholesale buyers?

MOQ varies based on packaging requirements and order customization. For standard orders, we maintain flexible quantities suitable for both trial purchases and bulk restocking. Contact us with your required volume and we’ll provide a tailored quotation.
