For on- and off-highway applications, Primaax heavy-duty air suspension reduces suspension-induced driveline vibration. Forged support beams, outboard-mounted torque rods and a crossbeam deliver optimal roll stiffness—a benefit to applications such as redi-mix, dump, refuse and logging. With a 46,000-pound rating, Primaax can be used with multiple lift axles.
