Introduction

The 1707030 Fast Drive Gear is an essential high-precision transmission gearbox component for heavy-duty trucks. As the core high-speed driving gear inside the transmission system, it cooperates with the input shaft and driven gears to undertake high-speed power transmission and gear matching, directly supporting the vehicle’s high-speed cruising performance. Manufactured with high-strength alloy steel and professional integral forging and precision tooth grinding technology, this drive gear features high surface hardness, strong wear resistance and stable high-speed meshing performance. It effectively solves common gearbox faults such as gear meshing noise, tooth surface wear, power jitter and speed transmission failure caused by aging or damaged original gears. It ensures smooth gear shifting, stable power output and reliable high-speed driving safety, serving as a standard OEM replacement part for heavy truck gearbox repair and overhaul.

Key Features

✅️Exact OEM Standard Fit 

Strictly produced according to original gearbox factory specifications with standard part number 1707030. The gear tooth modulus, tooth count, outer diameter, thickness and spline parameters fully match original equipment. No modification is required for direct installation, perfectly compatible with heavy-duty truck gearbox assembly requirements.

✅️High-Strength Forged Alloy Material 

Adopts premium alloy steel raw materials with integral forging and multiple strict heat treatment processes. The gear body achieves ultra-high overall hardness and strong structural toughness, effectively resisting high-speed meshing impact, torque pressure and friction wear, not easy to crack, deform or peel off.

✅️Precision Tooth Grinding & Smooth Meshing 

Adopts advanced CNC fine grinding and finishing technology. The tooth surface is smooth with precise tooth pitch and uniform meshing clearance. It realizes tight and stable gear meshing, effectively reduces transmission resistance, eliminates abnormal gear noise, and avoids gear jumping and power loss during high-speed operation.

✅️Superior Wear & Fatigue Resistance 

Professional surface carburizing and quenching treatment greatly enhances tooth surface wear resistance and high-temperature fatigue resistance. It adapts to long-term high-speed rotation and frequent gear shifting working conditions, effectively delaying aging and extending the service life of the gearbox transmission system.

✅️Stable High-Speed Transmission Performance 

Optimized gear structure design ensures uniform force distribution and stable power transmission. It effectively improves vehicle high-speed driving stability, solves problems such as weak acceleration and fluctuating speed, and restores the gearbox’s original efficient transmission performance.

✅️High Cost-Effectiveness & Wide Applicability 

Factory direct supply with strict quality inspection and performance testing, reaching OEM quality standards with competitive pricing. Widely applied to various heavy-duty truck gearbox models, it is a popular aftermarket replacement part for fleet maintenance, repair workshops and global spare parts wholesale across Middle East, Africa and Central Asia markets.
