A mounting bracket system for mounting rear fenders to a semi-truck includes a front mounting bracket, a rear mounting bracket, and a fender support member. The mounting brackets include a combination of planar sections, sloped bridge sections interconnecting the planar sections, and interconnecting gussets for support and durability.

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 optically and aerodynamically improved body for a motor vehicle has a wheel well cover with at least one wheel well for receiving a wheel. The wheel well cover is designed in such a way as to be adjustable by an adjusting mechanism in accordance with the wheel angle, and includes at least two ring portions which surround part of the wheel and which are arranged in such a way as to be movable at least partially into each other and at least partially relative to one another.

A fender assembly for an agricultural tractor including a carrier bracket which supports a wheel fender adjacent to a vehicle wheel. A steering mechanism is provided as part of the fender assembly, such that the wheel fender can be rotated relative to the carrier bracket. Accordingly, the rotation of the wheel fender can be controlled based on a steering signal generated by the vehicle steering system, to ensure that the wheel fender accurately follows the movement of the adjacent tractor wheel.

A fender assembly for a tractor, as well as a tractor having such a fender assembly. The fender assembly is constructed as first and second fender parts, connected via a rail. The rail has a partial spiral or helical shape. As a result, the second fender part is moveable on the rail along a path substantially parallel to a portion of the circumference of a wheel of the tractor, in a direction downwardly and outwardly relative to the first fender part. This provides a fender assembly allowing for improved access to tractor components located inboard of the fender assembly, as well as allowing for ease of access to the second fender part for an operator standing on the ground adjacent the tractor.

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.

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.
