Hendrickson has partnered with Navistar to offer HAULMAAX EX as a part of the chassis enhancements of the International HX. HAULMAAX EX is designed to address the growing demand for rubber suspensions across all vocational applications. The HAULMAAX EX suspension is optimized to provide increased site rating, expanded capacity ranges, and improved durability. The suspension offers a balance of unloaded ride quality and loaded stability, as well as the versatility needed for trucks and tractors that operate both on-and off-highway. 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. HAULMAAX EX offers capacities of 40,000, 46,000, and 52,000 lbs.
