Abstract: The present invention relates to a mud flap lifting system for raising and lowering a pair of mud flaps connected to a rear portion of a vehicle and suspended behind corresponding rear wheels of the vehicle. A shaft extends between the mud flaps. First and second sheaves are disposed on the shaft, wherein each of the sheaves is aligned with one of the mud flaps. A pair of cables is provided, each of the cables having a first end connected to one of the sheaves and a second end connected to the correspondingly aligned mud flap. A motor is coupled to the shaft, wherein the shaft is axially rotated upon actuation of the motor. Each of the cables is coiled around the corresponding sheave upon rotation of the shaft in a first direction, thereby raising the mud flaps.
