Hendrickson Truck Suspension Systems is supplying Paccar’s sister OEMs, Peterbilt and Kenworth, with a new lightweight suspension designed specifically for their heavy-duty vocational truck and tractor models. Dubbed the Haulmaax, the suspension will be available exclusively on new trucks ordered through dealerships of the two OEMs. According to Sean Coleman, marketing manager for Hendrickson Truck Suspension Systems, the key advantage of the Haulmaax is that it weighs less to allow higher payloads but is manufactured with high-strength materials and advanced techniques to ensure durability. The suspension is also engineered for ride quality. “Haulmaax uses an innovative spring geometry that couples natural rubber with a high-density thermoset material for the preferred ride and handling characteristics desired in construction, refuse, logging and other heavy-duty applications,” said Coleman. “This premium system adjusts to the load, providing excellent ride quality and loaded stability.” As for weight savings, according to Coleman, Haulmaax provides “over 500 lbs. of additional payload in comparison to competitive steel-spring suspensions.”
