Kenworth’s Neway ADZ rear air suspension from SAF-Holland for heavy duty and severe duty applications is for typical heavy duty applications, such as construction trucks, loggers, and fire apparatus and emergency vehicles. The suspension also is for severe-duty applications where heavy vertical loads, high gross combination weights, high torque drive trains, high center of gravity loads, and significant off-road travel are expected. Available in 23,000- and 26,000-lb. capacities per axle, the Neway ADZ is engineered for independent single suspension mounting that allows for single, tandem or tridem axle truck or tractor applications. The ADZ series, which replaces the AD series suspension for over-the-road applications, incorporates a simplified light weight V-rod construction that replaces the traditional track and torque rods.
