Peterbilt to offer Haulmaax suspension

Truck maker Peterbilt Motos Co. of Denton, TX, plans to make the Haulmaax suspension line from Hendrickson International available on its vehicles. Both Peterbilt and its parent company, Paccar Inc., worked with Hendrickson to develop this new suspension, optimizing its design and that of the associated crossmembers for Peterbilt's tractors and vocational line of trucks. The Haulmaax is now available in 40,000- and 46,000 pound ratings for Peterbilt Models 379, 378, 385, 357, 362 and 320. It is also available for the Peterbilt Model 330 in a Class 8 configuration. Optional shock absorbers are available to further improve ride and handling in most applications."The Haulmaax suspension can help decrease vehicle weight by hundreds of pounds, translating into increased payloads," said Dan Sobic, Peterbilt assistant general manager. He added that it also features a "spring geometry" design that couples natural rubber with a high-density thermoset material for superior strength while enhancing ride and handling characteristics for vocational applications.
