"Primaax EX has grown tremendously in popularity over the years and has become widely accepted by fleets throughout the industry as their preferred 100% off-highway approved vocational air suspension for multiple severe-duty applications," says Sean Whitfield, director of marketing at Hendrickson Truck Vehicle Systems. "We are excited to launch the new 12-in., ride height as well as the 52,000-lb., air disc brake compatible variants offered at International to expand the availability of Primaax EX across the full breadth of their vocational model lineup to bring the tremendous advantages of Primaax Ex to more International customers."
The new variant of the Primaax EX suspension is designed specifically for the rigorous demands of vocational and severe-service such as construction, refuse, mixer, logging and heavy-haul applications. The new 12-in., ride height system variant contributes to better weight distribution, improving stability and control under heavy loads.

Primaax EX aims to minimize suspension induced driveline vibration and controls suspension windup and corresponding frame rise. Premium heavy-duty rubber bushings require no lubrication and are performance-tested for longer service life. The taller Primaax EX ride height option will help fleets comply with Canadian regulations related to vehicle dimensions and load capacity as well as applications that require a slightly taller than standard ride height.
Primaax EX offers a full range of suspension scalability from 23,000-lb., single axle configurations up to 78,000-lb., tridem setup configurations.
