kscarbel2 Posted February 10, 2020 Share Posted February 10, 2020 Hendrickson Press Release / February 7, 2020 With its rugged, weight efficient design, PRIMAAX® EX is a severe-duty vocational air suspension that delivers advanced suspension technology for the rigorous demands of vocational, severe-service, and heavy-haul applications. The system features a robust structural design with optimized suspension geometry for exceptional stability, handling and ride. Suspension-induced driveline vibration is significantly reduced with PRIMAAX EX compared to competitive trailing-arm air suspensions, resulting in higher driver comfort and less premature wear on expensive truck and body equipment. .

Bullheaded Posted February 10, 2020 Share Posted February 10, 2020 Anyone know why the leveling valves repeatedly fall off new Mack Granite's with this suspension? The big local construction company here bought a bunch of new Granites, both dump trucks and Granite HOS sleeper float tractors, and the leveling valves continuously fall off them? I haven't looked at one up close to know what is going on. Their new Stars have the same suspension and don't seen to suffer. Quote Link to comment Share on other sites More sharing options...

fjh Posted February 10, 2020 Share Posted February 10, 2020 We have sold a fare few units of this in version One ! This here appears to be a much better version over the first version of this unit ,the torque arms on version one, were always coming loose at the axle end! The dog bone at both ends of the torque arm appears to be a an much needed upgrade! See how it goes ! Quote Link to comment Share on other sites More sharing options...
