The Fifth Wheel Height is the distance from the ground to the bottom of gooseneck at the fifth wheel plate. This height is designed to match the tractor's Fifth Wheel Height. When the Fifth Wheel Height is not the same as the tractor, the lowbed trailer will not ride level and the weight may not be properly distributed across the axles.

Flag Holders are a steel tube sized to hold safety flags could be added to the front or rear corners of the trailer deck.

The Flip Axle is a complete axle assembly frame attached to the rear frame by hinge plates and pins. The Flip Axle is used when the trailer's axle loading exceeds the gross weight that a given state will allow on each axle. Otherwise, the Flip Axle can be flipped up onto the rear frame, or removed, to reduce the number of axles. All ROGERS removable axles are on air ride suspensions. The Flip Axle connects to the trailer's leveling valve if the flip axle is to be used with an air ride trailer; or comes with a hand control valve if the flip axle is used on a trailer with a mechanical suspension.

Flush Hinges describes the option where the top hinges for a removable axle assembly are mounted below the top surface of the rear frame of the trailer and removable axle. Ordinarily the hinge plates are welded to the top of the trailer rear frame and removable axle frame.
