## Abstract

A system and method for adjusting the arms of an over-sized trailer is described herein. In one embodiment, the system can comprise a center support, a plurality of swing arms, and a plurality of stabilizer rods. The swing arms can be mounted to the left side and the right side of the center support. The swing arms can each comprise an arm and an arm hinge. The swing arms can be capable of rotating about the arm hinge. Furthermore, a dolly can be capable of being mounted to each swing arms. Each of the stabilizer rods can comprise a first rod portion and a second rod portion. The first rod portion can be connected to the center support and the second rod portion connected to one of the swing arms.
