Hendrickson partners with Freightliner on new rear suspension

Hendrickson Haulmaax-Ex

Hendrickson Truck Commercial Vehicle Systems have 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 provides versatility for trucks that operate both on-and off-highway. Equalizing beams on the suspension are designed to 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 Hendrickson TRAAX ROD torque rods, 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 at Hendrickson.

“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,” Dudding continued.
