Differential Pinion Shaft
Mack

The differential pinion shaft is a critical element in the vehicle’s drivetrain, supporting the pinion gear and enabling smooth power transfer from the driveshaft to the axles. Its precise manufacturing ensures proper gear meshing and reduces wear, which is essential for maintaining differential performance. Made from high-strength materials, it resists deformation under torque loads and harsh conditions. Proper maintenance and replacement of this shaft are vital for preventing differential failure and ensuring consistent power delivery. This component is fundamental for the durability and efficiency of the drivetrain system. Source One Parts Center provides this essential part to support your vehicle’s drivetrain integrity.
