Introduction

The 1707146-1 Synchronizer Assembly is an essential core transmission component exclusively designed for FAW series heavy-duty trucks. Installed inside the gearbox system, it is responsible for balancing the speed difference between gears during shifting, realizing smooth gear meshing and seamless gear switching. This synchronizer assembly effectively solves harsh shifting, gear impact and shifting jitter problems caused by speed mismatch. Manufactured with high-strength alloy materials and precision grinding technology, it features high wear resistance, strong impact resistance and stable transmission performance. It adapts to frequent shifting and heavy-load driving conditions of heavy trucks, ensuring stable and efficient operation of the vehicle transmission system, and is a perfect OEM replacement part for gearbox maintenance and overhaul.

Key Features

✅️Exact OEM Matching & Plug-and-Play Installation 

Produced strictly in accordance with FAW factory original technical standards with standard part number 1707146-1. It fully matches the installation size, tooth parameters and assembly interface of FAW heavy truck gearboxes. No modification or adjustment is required for direct installation, perfectly restoring original gearbox shifting performance.

✅️High-Strength Alloy Material & Impact Resistance 

Adopts high-grade alloy steel and integral forging molding process, with strict heat treatment and hardness strengthening. The overall assembly features high hardness, strong compression resistance and excellent fatigue resistance, capable of resisting instantaneous impact force during frequent gear shifting, not easy to wear, deform or crack.

✅️Smooth Shifting & No Gear Impact 

Precision friction ring and tooth sleeve structure design realizes accurate speed synchronization. It eliminates gear collision, shifting noise and stalling during upshifting and downshifting, making gear shifting smoother and more flexible, greatly improving driving experience and transmission stability.

✅️Excellent Wear Resistance & Long Service Life 

Adopts advanced surface polishing and anti-wear treatment technology, with uniform internal friction coefficient and stable working performance. It can adapt to long-term high-intensity shifting operations and complex road condition driving, effectively delaying component aging and extending the overall service life of the gearbox.

✅️Stable Transmission & Low Failure Rate 

Strict factory dynamic balance test and precision assembly ensure sensitive synchronization response and stable operation. It effectively avoids common gearbox faults such as difficult shifting, gear jumping, transmission power loss and abnormal noise, reducing vehicle downtime and maintenance frequency.

✅️Cost-Effective & Widely Applicable 

Factory direct supply with complete quality inspection, reaching OEM original quality level with competitive price. It is widely applicable to various FAW series heavy-duty trucks, ideal for fleet maintenance, repair shops and global spare parts wholesale, and enjoys high recognition in Middle East, Africa and Central Asia aftermarket.
