SX4 Four-Axle Side Dump

SmithCo’s SX4 series works in states that allow extended weights and is usually used in a line-haul application. The SX4-4936 is the more popular length. Some states allow extended weight but cap the number of axles you can use, sometimes a shorter trailer with more axles will fit your application better. Because the load dumps to the side, axle locations are not restricted like other dump trailers. Lift axles and steerable axles are common options on this series.
