Hendrickson's Primaax EX system is an enhanced version of the Primaax heavy-duty, vocational truck air suspension, for expanded applications.
The new system improves durability and performance while delivering a substantial weight savings alternative to competitive systems.

Refinements include enhanced joint integrity and durability, improved handling, increased air spring capacity, greater disc brake compatibility and improved resistance to torque rod bushing walk-out.

The system features cast austempered and shot-peened ductile iron support beams that integrate the attachment points for greater reliability. Hendrickson manufactures the beams and supplies them as an engineered sub-assembly to ensure control of product specifications for optimal performance and durability.

Primaax EX geometry features a new frame hanger and torque rod configuration. This provides increased roll stiffness and reduced roll steer for improved handling. Suspension-induced driveline vibration is also reduced with this system.

The new air springs lift and support the load with less air pressure. The packaging improvements help reduce potential damage to the sir spring.

Primaax EX will be available at most major truck manufacturers in capacities ranging from 23,000 to 26,000 pounds for single-axle, 46,000 to 52,000 pounds for tandem-axle and 69,000 to 78,000 pounds for tridem-axle applications.
