The Trail King TKSA Sliding Axle cycles from transport to loading position and back in 61 seconds, which is the number that matters on a trailer whose job is uptime. It is engineered for speed, increased swing clearance and a low 7-degree load angle, with a tilting main deck that forms a ramp to the upper deck. Two models cover 80,000 and 110,000 lb uniform capacity on a perimeter frame gooseneck design.
