Abstract
A vehicle suspension assembly includes a trailing axle carried by a frame of the assembly. The frame can retract to a retracted state from an extended state and extend from the retracted state to the extended state. The retraction and extension can occur along a longitudinal axis of the frame. An operator can pivotally raise and lower a free end of frame in the retracted or extended state along an arcuate path when the vehicle suspension assembly connects to a vehicle.
