Hendrickson Truck Commercial Vehicle Systems has partnered with Freightliner Trucks to offer the company’s Haulmaxx EX heavy-duty rear rubber suspension system as part of the chassis enhancements for all Freightliner Vocational M2, SD and Plus models.
Hendrickson says the suspension system is designed to provide 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. When paired with the company’s Traax Rod torque rods, the manufacturer says stability is enhanced and articulation increased for improved on/off-highway operation.
“Customers today expect more out of their vocational suspensions. Haulmaxx EX exceeds expectations by expanding on the capabilities of the original Haulmaxx design, with up to a 70,000-pound jobsite rating for the 46,000-pound capacity suspension,” stated Ashley Dudding, director of engineering at Hendrickson. “Haulmaxx EX is extremely rugged, supporting demanding vocational applications and offering capacities of 40,000 pounds, 46,000 pounds, and now 52,000 pounds.”
