Differential Side Gear
Mack

The differential side gear is a crucial component within the axle assembly, responsible for transmitting torque from the drive shaft to the wheels while allowing them to rotate at different speeds. This function is vital during turns, where wheel speed discrepancies occur, ensuring smooth handling and reduced tire wear. Made from high-strength materials, the side gear must withstand significant forces and resist wear over prolonged use. Proper maintenance and timely replacement of this part are essential to prevent differential failure, which could lead to costly repairs and vehicle downtime. Source One Parts Center provides high-quality differential side gears designed for durability and optimal performance, supporting the drivetrain's reliability in demanding conditions. Ensuring the integrity of this gear is fundamental to maintaining vehicle traction and overall operational safety.
