A vehicle-towed trailer includes a trailer frame, at least two wheels, and an independent suspension system securing each wheel to the frame. The independent suspension system includes a rotatable suspension rod supported by the frame and a trailing arm secured to the suspension rod. The trailing arm is adapted to pivot relative to the vehicle frame as the suspension rod rotates and includes a hub adapted to support one of the wheels. A bellcrank is secured to the suspension rod and is adapted to pivot relative to the vehicle frame as the suspension rod rotates. The bellcrank is spaced angularly relative to the trailing arm about the axis of the suspension rod. A spring member is pivotably secured on one end to the frame and on the other end to the bellcrank. The spring member is compressed and extended as the bellcrank pivots relative to the vehicle frame.
