Hendrickson Truck Commercial Vehicle Systems announced a partnership with Freightliner Trucks to offer Haulmaax EX — Hendrickson’s next generation heavy-duty rear rubber suspension system as a part of the chassis enhancements for all Freightliner Vocational M2, SD, and Plus models.

The Haulmaax EX suspension is designed for trucks that operate both on-and off-highway. Equalizing beams on the suspension distribute the load equally between both axles to maintain traction in off-road and uneven terrain conditions. An integrated jounce stop protects the spring system from over compressing, helping to extend component life, and when paired with Hendrickson Traxx Rod torque rods, stability is enhanced.  

“Haulmaax EX expands on the capabilities of the original Haulmaax design, with up to a 70,000-pound job site rating for the 46,000-pound capacity suspension," said Ashley Dudding, director of engineering at Hendrickson in a statement. “Haulmaax EX is extremely rugged, supporting demanding vocational applications, and offering capacities of 40,000 pounds, 46,000 pounds, and now 52,000 pounds. Hendrickson utilized our industry-leading analysis and validation techniques to ensure Haulmaax EX would meet these rigorous demands, minimize maintenance requirements, and deliver an advanced, lightweight vocational suspension to the market.”
