What makes our dump trailers SUPERIOR?

Superior’s patented U-shaped body and exclusive Koester fifth wheel makes our trailers strong, versatile, and durable. Our innovative design of straight sides and curved bottom forces material into the center of the trailer, making loading, hauling, and unloading easier. This control of the load means no bent or broken cross members and no washboarding. Our exposed cylinder has a tremendous advantage that eliminates areas of the load from sticking or freezing. The patent-pending Koester fifth-wheel plate makes it possible to pull a frame or frameless trailer without any modifications after the initial adjustment.
