Hendrickson has made Haulmaax, a lightweight, heavy-duty rear suspension, available on International Truck and Engine Corp 5000i and 7000 series vocational trucks.
This new variable- rate spring system helps cushion more than just the driver. It also helps protect the cab, chassis, and body equipment from vibration and harshness.
By eliminating the center bushings and providing easy access to all components, Haulmaax helps reduce maintenance costs for truck owners. The spring system helps promote long service life and easy accessibility, while the bar pin axle connection extends bushing life and provides alignment capability for better tire wear.
