The Hendrickson Roadmaax Z line of rear air suspension systems feature capacities of 23,000 pounds; 46,000 pounds; and 69,000 pounds and are approved for use with lift axles.
The Roadmaax 230, 460, and 690 are approved for 25% off-highway operation and feature Traxx Rod torque rods that maintain axle position and lateral stability. The rods are made with retained rubber bushings for increased service life and resistance to walkout, according to the company.
Roadmaax Z includes Zero Maintenance Damping (ZMD) ride technology, eliminating conventional shock absorbers and integrating the damping function into the air springs to help reduce downtime and maintenance costs over the life of the vehicle, according to the company.
