Kenworth announced that it now offers the Hendrickson Haulmaax EX as an option for the Kenworth T880, W990, T680 and T480 models. According to Hendrickson, this next generation heavy-duty, lightweight rubber suspension is designed for vocational applications such as dump, concrete mixer, refuse, logging, crane/boom, platform, and fire/rescue.. The new suspension replaces the Hendrickson Haulmaax family of 40,000- and 46,000-lb. capacity suspensions and also adds a new 52,000-lb. capacity.

In addition to the increased capacity range, the Hendrickson Haulmaax EX provides a higher site rating and maintains the same weight and durability compared to its predecessor. The suspension utilizes a unique rubber spring design that balances empty-ride quality and loaded stability. Angled bolster springs and a unique progressive load spring provide extra stability for demanding applications such as refuse, concrete mixers and dumps.
