Innovative. Integrated. Efficient.
Load up on the wide range of features and capabilities inside every Mack axle.
Complete Integration
Fully integrated with Mack’s MP® engines, transmissions and suspensions, this complete powertrain is designed to work seamlessly together for maximum efficiency and minimum maintenance.
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.
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.
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.
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.
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.
