Load up on the wide range of features and capabilities inside every Mack axle.
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.
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.
With the new 85,000 lbs. weight rating. Mack axles are the clear choice for heavy-duty auling without the worry.
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.
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 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.
