2024 SmithCo Side Dump Trailers SX3 SX3 4436

SmithCo’s SX3 Three Axle side dump is a popular choice in states allowing extended gross weights for truck/trailer combinations with more than five axles. The SX3-4234 and SX3-4636 are the most common three axle trailer sizes but lengths run from SX3-3734 to SX3-5036.

Shorter to mid-length trailers tend to be used for everyday construction jobs, while the longer three axle trailers are frequently used for line-haul applications.
