Construction & Design

Yukon’s ring and pinion gears are crafted from premium-grade alloy steel, selected for its strength and fatigue resistance. The gears undergo a state-of-the-art heat treatment process that hardens the surface while maintaining a tough core, resulting in exceptional durability and long service life. Precision machining ensures that the gear teeth mesh perfectly, reducing noise and vibration while maximizing power transfer efficiency.
