Introduction

The 16118 Sliding Sleeve is a critical precision shifting component specially designed for FAST heavy-duty truck gearbox systems. As the core moving part of the gearbox synchronizer and shifting mechanism, it slides axially on the main shaft to engage and disengage gears, realizing accurate gear switching and stable power transmission. Manufactured with high-strength alloy steel and precision integral forming technology, this sliding sleeve features smooth surface finish, high hardness and excellent wear resistance. It effectively solves common gearbox problems such as difficult shifting, gear jumping, shifting jitter, gear collision noise and unsmooth gear engagement caused by worn, deformed or stuck sliding sleeves. It ensures flexible and reliable shifting operation under frequent gear change and heavy-load driving conditions, serving as a premium OEM replacement part for FAST gearbox maintenance and overhaul.

Key Features

✅️Exact OEM Standard Fit 

Produced strictly according to FAST gearbox original factory specifications with part number 16118. The inner spline precision, outer tooth size, overall thickness and sliding tolerance fully match original gearbox parameters. No modification required for direct installation, perfectly compatible with matching FAST heavy-duty gearbox models.

✅️High-Hardness Alloy Steel Material 

Adopts high-quality alloy steel with integral forging and heat treatment. The sliding sleeve body features high surface hardness and strong structural toughness, effectively resisting friction, impact and extrusion during frequent shifting. It is not easy to deform, wear or crack under long-term high-intensity working conditions.

✅️Precision Machining & Ultra-Smooth Sliding 

Adopts advanced CNC fine grinding and precision finishing process. The inner spline and outer tooth surface are extremely smooth with precise tolerance control. It ensures flexible axial sliding, no jamming or stagnation during gear shifting, greatly improving shifting smoothness and driving experience.

✅️Excellent Wear Resistance & Long Service Life 

Professional surface strengthening treatment enhances anti-wear and anti-fatigue performance. It adapts to long-term frequent shifting, high-speed operation and chassis vibration, effectively reducing component wear and avoiding early failure, extending the overall service life of the gearbox shifting mechanism.

✅️Eliminate Common Gearbox Faults 

Standard tooth position and accurate meshing performance thoroughly solve typical faults including gear jumping, loose gear engagement, shifting noise and power transmission instability. It restores sensitive and accurate gearbox shifting performance and improves driving safety.

✅️High Cost-Effectiveness & Wide Applicability 

Factory direct supply with strict quality inspection and dimensional testing, reaching OEM quality standard at competitive price. Widely used for heavy-duty trucks equipped with FAST gearboxes, it is a hot-selling aftermarket part for fleet maintenance, repair workshops and global spare parts wholesale in Middle East, Africa and Central Asia markets.
