HAULMAAX®

Heavy-duty Rubber Suspension

HMX

Hendrickson Defense’s HAULMAAX® is a premium rubber suspension designed for vocational applications where durability, lightweight and driver comfort are essential. HAULMAAX's innovative low-maintenance design utilizes rubber bolster springs coupled with progressive load springs that provide a superior combination of empty ride quality and loaded stability. The lightweight design offers up to 690 lbs. of weight savings versus competitive vocational rear tandem suspension. In addition, up to 17 inches of diagonal articulation help keep the axle in traction for superb off-road mobility.
