Versatile Construction

Choose between durable cast ductile iron axle housings built with thicker walls to handle the most extreme jobs or our lighter weight fabricated steel axle housings for improved efficiency.

Mack Trucks Granite

The Heavy-Duty Heavyweight

With the new 85,000 lbs. weight rating. Mack axles are the clear choice for heavy-duty auling without the worry.

Mack Trucks Driveline

Top-Mounted Design

Top mounting our carriers delivers a straight-through driveline that cuts down on vibration and reduces lifetime maintenance costs while delivering a quieter, smoother drive.

Mack Axle housings

Uptime By Design

Our axle housings have tighter tolerances and fewer joints for greater reliability and longer life. The top-mounted carrier features a bowl cover on the top of the housing making it less prone to leaks.

Mack Axle Ground Clearance

Greater Ground Clearance

Mack axles have up to nearly 2” of greater ground clearance over our competitors which means greater maneuverability while reducing the potential for high rock damage.
