Hendrickson is now offering its Next Generation Haulmaax EX suspension as a part of the chassis enhancements for Autocar's ACX and DC-64TM models.

The Haulmaax EX supports demanding vocational applications and offers capacities of 40,000 lbs., 46,000 lbs., and  52,000 lbs., according to Ashley Dudding, director of engineering for Hendrickson, with up to a 70,000-pound site rating for the 46,000-pound-capacity suspension.

The Haulmaax EX provides the versatility needed for trucks and tractors that operate both on-and off-highway, according to the company. The suspension’s equalizing beam distributes the load equally between both axles in off-road and uneven terrain conditions. The design eliminates fixed center bushing pivot points to reduce wheel hop. When paired with Hendrickson Traax Rods, stability is enhanced, and articulation increased for improved on/off-highway operation.

First announced in 2019, the Haulmaax EX has since been made available for a number of vocational models, including ones from Western Star, International, Freightliner, and Kenworth.
