Freightliner has partnered with Hendrickson Truck Commercial Vehicle Systems to offer the company’s Haulmaax EX rear rubber suspension system as a part of the chassis enhancements for all Freightliner Vocational M2, SD and Plus models.

“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 Hendrickson Director of Engineering Ashley Dudding. “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.”

The Haulmaax EX is designed for both on- and off-highway trucks, according to a Hendrickson press release. Equalizing beams on the suspension are made to distribute the load equally between both axles to maintain traction in off-road and uneven terrain conditions. An integrated jounce stop is designed to protect the spring system from over compressing in an aim to extend component life and reduce maintenance costs.
