A mud flap is attachable to a selected group of through-holes of a vehicle running board. Plugs clamp to inclined surfaces of the through-holes, thereby firmly affixing a bracket portion of the integrally molded mud flap body to the running board. A flap portion of the mud flap body is connected to the bracket portion of the mud flap body only by a hinge portion. The hinge portion has a straight front surface, a straight rear surface and a thickness that is less than the overall thickness of the mud flap body. The flap portion has at least one wall portion that does not conform to any yz plane, stiffening the flap portion and inducing it to rotate around the hinge portion as a unit when a front-to-rear shear force impinges on the flap portion. A notch may be formed to interrupt an otherwise convexly curved rear flap portion surface so to receive a downwardly depending running board reinforcing member when the flap portion flexes out of its rest position.

A mudflap for a vehicle, configured to be installed on the vehicle, comprising a base layer, configured to be attached to the vehicle; and an exposed layer, configured to be attached to the base layer and movable between an operation position, in which the exposed layer is attached to the base layer, and a cleaning position, in which the exposed layer is detached from the base layer; the base layer comprising a plurality of protrusions and the exposed layer comprising a plurality of orifices, the protrusions of the base layer being engaged in the orifices of the exposed layer when the exposed layer is in its operation position.

Embodiments provide an aerodynamic fairing system that may comprise a base configured to mount to a vehicle, an arm coupled to the base at a proximate end and extending laterally, and a fairing mounted to the arm having an inboard and an outboard surface. The fairing outboard surface may provide an aerodynamic outer surface to direct flow to an angle to the rear. The arm may a fixed or adjustable length arm. The arm may provide a mounting area for a mud flap such that aerodynamic system may act as a mud flap hanger. Embodiments also provide an adjustable mud flap hanger.

An apparatus for providing a vehicular fender extension comprise a wheel-well casing having a top surface, a bottom surface, an inside edge and an outside edge, the wheel-well casing being adapted to fit within a vehicular wheel-well, a guiderail located at the outside edge of the wheel-well casing, and an extending member slideably supported by the guiderail, the extending member having a top surface, a bottom surface, an inside edge and an outside edge, extending between first and second ends. The apparatus further comprises at least one actuator operable to move the extending member between a first position wherein the extending member is contained within the wheel-well casing, and a second position wherein the outside edge of the extending member is distal from the outside edge of the wheel-well casing.

Mud flap assemblies including a frame, a securing assembly and mud flap panels; the securing assembly enabling the frame to be secured to a hitch assembly having a shaft, for further attachment to a hitch receiver secured to a vehicle; the frame having two side portions secured to a center portion to which the securing assembly is attached. The center portion of the frame is preferably configured to rest on a portion of a bumper of the vehicle to minimize vibration of the frame during use. The frame includes two side portions having channels within which reside at least a portion of fasteners that attach mud flap panels to each of the respective side portions. Methods of installing mud flap assemblies and attaching the flap panels are also disclosed.

A spray protection device (1) for a wheeled vehicle (20) having at least one wheel (21) standing on the ground, said device (1) comprising a spray shield (2), suitable for being arranged at least in part behind the wheel (21), and connection means (3) for connecting the shield (1) to said vehicle (20), the spray shield (2) presenting a face suitable for facing towards the wheel (21) to be protected and an opposite face, referred to as the back of the shield (2), the connection means (3) for connecting the shield (2) to the vehicle (20) being configured, when the shield (2) is coupled to the vehicle (20), to enable the shield (2) to move between a high position, at a distance from the ground, and a low position, close to the ground.

The device (1) comprises resilient shield (2) return means in the high position and a surface carried by the shield (2) and suitable for being exposed to the airflow generated when the wheeled vehicle (20) is moving forwards, said surface being configured, under the action of said airflow, to enable the shield (2) to move in a direction that is opposite to the direction of the return force.

An apparatus for providing a vehicular fender extension comprise a wheel-well casing having a top surface, a bottom surface, an inside edge and an outside edge, the wheel-well casing being adapted to fit within a vehicular wheel-well, a guiderail located at the outside edge of the wheel-well casing, and an extending member slideably supported by the guiderail, the extending member having a top surface, a bottom surface, an inside edge and an outside edge, extending between first and second ends. The apparatus further comprises at least one actuator operable to move the extending member between a first position wherein the extending member is contained within the wheel-well casing, and a second position wherein the outside edge of the extending member is distal from the outside edge of the wheel-well casing.

A weight is provided for a mud flap with the mud flap having an upper end, a lower end, a first side, a second side, a front side and a rear side. The weight of this invention is comprised of a first support member and a second support member. The first support member is positioned at the rearward side of the lower end of the mud flap and the second support member is positioned at the front side of the mud flap at the lower end thereof. Bolts extend through the first support member, the mud flap and the second support member to secure the weight to the lower end of the mud flap.

In some embodiments, a tire tread collection device is provided which may be coupled to any vehicle preferably having one or more tires. The device may include one or more vertical supports which may be coupled to a debris screen. The debris screen may have a first end, with a collection aperture, and a second end. The first end and collection aperture may be positioned behind and proximate to one or more tires of a vehicle. Preferably, the device may include a first vertical support and a second vertical support which may each be coupled to opposite sides of the collection aperture and which may also be coupled to an opposing side of the vehicle so that one or more tires are positioned approximately between the vertical supports. Tire debris thrown from the tires may enter the debris screen through the collection aperture of the first end and be retained therein between the first end and the second end.

Mud flap assemblies including a frame, a securing assembly and mud flap panels; the securing assembly enabling the frame to be secured to a hitch assembly having a shaft, for further attachment to a hitch receiver secured to a vehicle; the frame having two side portions secured to a center portion to which the securing assembly is attached. The center portion of the frame is preferably configured to rest on a portion of a bumper of the vehicle to minimize vibration of the frame during use. The frame includes two side portions having channels within which reside at least a portion of fasteners that attach mud flap panels to each of the respective side portions. Methods of installing mud flap assemblies and attaching the flap panels are also disclosed.
