WG2211040107 5th Gear for Main Shaft | Heavy Duty Truck Direct Drive Gear

WG2211040107 Spindle 5th Gear

The WG2211040107 main shaft five-speed gear is compatible with heavy-duty truck gearboxes. Made of high-quality alloy steel, it undergoes carburizing, quenching, and precision grinding, resulting in high tooth surface hardness, fatigue resistance, and impact resistance. It is less prone to tooth breakage and wear under heavy loads, ensuring a long service life. The fifth gear is a direct drive (1:1 ratio), providing direct power transmission, low loss, and low noise, resulting in smoother and more fuel-efficient high-speed cruising. The gear design and meshing precision are high, and the dynamic balance is optimized, resulting in low vibration and low noise, enhancing driving comfort. With ample stock and strong compatibility, it is the preferred accessory for heavy-duty truck gearboxes.

The WG2211040107 Main Shaft 5th Gear, also known as the direct drive gear, is a key transmission component designed for heavy-duty truck gearboxes.

It is responsible for stable power transmission in the direct gear position, ensuring smooth driving performance and reliable operation under high-load conditions. This gear is widely used in heavy-duty truck transmission assembly and aftermarket replacement.

Key Function

Provides stable direct-drive power transmission
Ensures smooth engagement in 5th gear position
Reduces shock during gear shifting
Protects transmission shaft system and bearings

Product Advantages

● High Strength & Heavy Load Resistance

Manufactured from high-quality alloy carburized steel and processed with deep carburizing and quenching technology, the gear features:

Excellent hardness and toughness balance
