2025 Load King 503/554 SS SF Lowboy Trailer

Owning the Load King 503/554 SS SF gives you a serious, no-nonsense hauling platform built for heavy, real-world work: a 55-ton rating with a hydraulic removable gooseneck lets you load low, fast, and safely without fighting ramps, while the air-activated self-locking pin and adjustable ride height make hook-ups and break-downs efficient on uneven ground. The full-depth cambered deck, air-ride suspension, and Hendrickson axles keep heavy equipment stable and predictable in transit, and features like the excavator trough, reinforced outriggers, and wide load package mean it’s ready for oversized machines without aftermarket compromises. Add in durable urethane paint, LED lighting, and a proven Honda pony motor, and you get a trailer that minimizes downtime, protects your equipment investment, and holds its value over years of hard use.
