Abstract
A trailer slider system includes a body rail that slides longitudinally relative to a suspension frame side rail. One of the rails includes holes that provide multiple suspension positions. The trailer slider system also includes a pin connection assembly having a pin that is arranged to extend into one of the holes in a locked position and retract out of the hole in an unlocked position. A cam is coupled for movement with the pin connection assembly. A tube is coupled with the cam to rotate as the pin moves between the locked and unlocked positions. A pneumatic actuator is coupled with the tube for selectively rotating the tube to move the cam which in turn moves the pin, between the locked and unlocked positions.
