Kenworth is rolling out updates to their Class 8 heavy-duty trucks line, including Hendrickson’s new Haulmaxx EX suspensions. This axle mounting system replaces leaf springs with a rubber spring system, and it uses a series of links to control axle movement. These suspension systems are an option on Kenworth’s T480, T680, T880, and W990 models.

Hendrickson EX Next Generation suspensions replaces the Haulmaxx family of 40,000 and 46,000-pound capacity suspensions. The EX also includes a new 52,000 lb. capacity model. These are approved for a GCW of 160,000, 190,000, and 245,000 lbs, respectively. These units use a unique rubber spring design built to improve ride quality when the truck is unloaded and improve stability when the truck’s rear is under load. Extra-wide spring centers angled bolster springs and a progressive load spring work to smooth out the ride while delivering the loaded stability needed for concrete mixers, refuse trucks and dump trucks. The ride isn’t just easier on the driver; it also saves wear and tears on components, leading to longer service lives. Shock absorbers can be added to improve driver comfort.

Unlike other walking-beam suspension systems, the Haulmaxx doesn’t have fixed center bushing pivot points. This helps eliminate wheel hop. It also means there’s one less thing to worry about when it comes to truck maintenance. The EX has up to 17 inches of diagonal wheel articulation, which helps heavy-duty trucks maintain traction when driving off-road. Torque rods resist wind up during acceleration and braking, saving wear and tear on drivetrain components. All three versions of this suspension can be used with lift axles.

Ride height for the Haulmaxx is between 9.5 and 13.25 inches. 40,000 lb. suspensions are available with 52 and 54-inch axle spacing, while 46,000 lb. breaks support 52 to 72.5-inch spacing. The new 52,000 lb. unit is available with 52, 54, and 60-inch spacing.
