For expanded application capabilities, Hendrickson recently launched the PRIMAAX EX system, an enhanced version of the PRIMAAX heavy-duty, vocational truck air suspension.

PRIMAAX EX improves durability and performance while delivering substantial weight savings. 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.

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

PRIMAAX EX geometry features a new frame hanger and torque rod configuration. This provides increased roll stiffness and reduced roll steer for improved handling. In addition, suspension-induced driveline vibration is reduced.

Expanded offerings of the longitudinal torque rods help provide extended bushing life, ease of serviceability, and improved compatibility to package with disc brakes.

Featuring improvements to the air spring piston shape and beam interface, the PRIMAAX EX air springs lift and support the load with less air pressure. Furthermore, packaging improvements help reduce potential damage to the air spring.

This suspension 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.
