Embodiments of the present disclosure provide a method and apparatus for reducing drag. An exemplary apparatus includes a semitrailer having a main frame extending along a longitudinal axis and a subframe movably connected to the main frame between a first position along the longitudinal axis and a second position along the longitudinal axis. The apparatus further includes an axle assembly attached to the subframe, the axle assembly including an axle, a left wheel set, a right wheel set, and a suspension, and a first recapture device located under the main frame behind and separated from the left wheel set along the longitudinal axis by a given spacing. The apparatus still further includes a second recapture device located under the main frame behind and separated from the right wheel set along the longitudinal axis by a second spacing.
