Hendrickson Launches Rubber Suspension for International HX

Hendrickson has partnered with Navistar to offer the Haulmaxx EX heavy-duty rubber suspension as a part of the chassis enhancements of the International HX.

“Just like the newly redesigned International HX Series, Hendrickson took a great suspension and made it better,” said Mark Stasell, VP, vocational https://www.aga-parts.com/bobcat/ truck business, Navistar. “The Haulmaxx EX delivers improved performance and durability, which helped our team design the new HX Series for productivity, durability, and comfort.”

With the updated vehicle’s release, Hendrickson will be launching its next-generation, heavy-duty rubber suspension Haulmaxx EX as the standard rubber suspension offering, addressing the growing demand for rubber suspensions across all vocational applications. The Haulmaxx EX suspension is optimized to provide increased site rating, expanded capacity ranges, and improved durability.

The suspension allows the ability to increase the payload of the vehicle, among other attributes. Its equalizing beam distributes the load equally between both axles in off-road and uneven terrain conditions, Hendrickson says. The design eliminates fixed center bushing pivot points to reduce wheel hop.

“Customers today expect more out of their vocational suspensions. Haulmaxx EX exceeds expectations by expanding on the capabilities of the current Haulmaxx design,” says Ashley Dudding, director of engineering for Hendrickson. “With up to a 70,000-pound site rating for the 46,000-pound capacity suspension, Haulmaxx EX is extremely rugged, supporting the most 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 Haulmaxx EX would meet these rigorous demands, minimize maintenance requirements, and deliver the lightest weight vocational suspension on the market,” Dudding says.
