PRIMAAX® EX Vocational Air Suspension Available at Kenworth


WOODRIDGE, Ill. - Kenworth Truck Company recently launched Hendrickson's PRIMAAX® EX heavy-duty vocational rear air suspension. In addition to 46,000 lb. tandem and 69,000 lb. tridem configurations, the next-generation version of PRIMAAX will also be available in new 52,000 lb. tandem capacity. Availability of the PRIMAAX EX system began November 2009, announced officials at Hendrickson Truck Suspension Systems.

PRIMAAX EX will be available at Kenworth Truck Company on a variety of chassis including the C500, T800 and W900 models.

The EX platform is a robust, yet lightweight vocational system that delivers the same benefits as prior PRIMAAX configurations with additional features designed to enhance durability, improve handling, and increase air spring capacity.

The PRIMAAX EX system features structural beams that integrate the cross beam attachment points for greater reliability, resulting in a solid connection to form a rigid torsion system for improved stability and control.

Featuring a new frame hanger and torque rod configuration, the PRIMAAX EX optimized suspension geometry contributes to enhanced roll stability, helps improve handling and roll stiffness for expanded applications and significantly reduces suspension induced driveline vibration.

Expanded offerings of the longitudinal torque rods help provide extended bushing life and ease of serviceability.

The new PRIMAAX EX air springs fill faster and lift and support the load with less air pressure. Furthermore, packaging improvements contribute to enhanced air spring durability.

PRIMAAX EX features superior ride, durability, stability and suspension articulation, proving ideal for versatile on- and off-highway applications.
