Hendrickson Truck Commercial Vehicle Systems announced that it has partnered 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, according to the company, provides the versatility needed 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 reduce maintenance costs, the company notes. When paired with Hendrickson Traax Rod torque rods, the company says that stability is enhanced, and articulation is increased for improved on/off-highway operation.  

“Customers today expect more out of their vocational suspensions. Haulmaax EX exceeds expectations by expanding 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, Hendrickson. “Haulmaax EX is extremely rugged, supporting demanding vocational applications and offering capacities of 40,000 pounds, 46,000 pounds, and now 52,000 pounds.”
