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, an 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.

A mud flap system for a tractor is described. The mud flap system includes brackets that clamp or secure to a frame of the tractor. Lateral extensions engage to the brackets to support covers over a top surface of rear wheels of the tractor.

An arm for mounting a fender to a vehicle includes a shell defining an internal channel. The shell features a proximal end portion and a distal end portion. A mounting plate is secured within the internal channel in the proximal end portion of the shell. The mounting plate includes a fastener opening, which receives a fastener to secure the arm to a vehicle. The distal end portion of the shell is adapted to be fastened to the fender.

The mudflap system with universal adapter is centered on a bracket. The bracket includes optional inserts that can be added or removed to change the size of the bracket recess. By changing the size of the bracket recess, a single bracket may be used on multiple sizes of ball mountthe ball mount being portion of the vehicle's hitch system that generally protrudes from the receiver, accepting trailer coupler to connect to the trailer. The bracket includes tab recesses interface with tabs present on the inserts. The tabs and associated recesses act to align the inserts with the bracket and prevent over-insertion, thereby preventing the inserts from falling out during assembly. After placement of an insert within the bracket, threaded fasteners are used to clamp the bracket to the ball mount and to hold the inserts in position.

A number of variations may include a method comprising fixing a wheel cover on a wheel so that the wheel cover remains static as the wheel rotates on a horizontal axis and turns with the wheel as the wheel turns on a vertical axis comprising attaching a bearing system to a knuckle of a wheel; and attaching the wheel cover to the bearing system and the knuckle.

Universal brackets comprising universal yokes that are compatible with a variety of yoke caps are disclosed. Selection of a particular yoke cap determines the size of an opening formed when the yoke and yoke cap are joined to form the bracket, which can be used, for example, in mudflap mounting systems that optionally include additional safety features, such as cylindrical clamps, bent support arms, flared rods, and reinforced mudflaps.
