Abstract: A preload collar for a vehicle spring is described. The preload collar is coupled to the shock absorber of a vehicle so that the lower end of the vehicle spring is pressing against the preload collar. The preload collar does not allow the lower end of the vehicle spring to extend toward the ground, or toward the lower end of the shock absorber, as much as it normally would. This pre-loading of the vehicle spring provides suspension lift to the vehicle.

Abstract: A multipurpose swing arm assembly for a vehicle accessory rack is described. The accessory rack includes a base rack that holds the multipurpose swing arm assembly, and a coupling assembly that couples the base rack and the multipurpose swing arm assembly to a hitch coupler of the vehicle. The multipurpose swing arm assembly is used to hold accessories for transported and use with the vehicle. The multipurpose swing arm assembly includes a multipurpose swing rod hingedly coupled to the base rack, and two cooler tray support rods. A cooler tray is coupled to the cooler tray support rods. A cooler is set on the cooler tray and coupled to the multipurpose swing arm assembly to be transported and used with the vehicle. A work top bar and a work top can also be coupled to the multipurpose swing rod to be used as a table top.

Abstract: A hitch coupling assembly that is used to couple an accessory to a vehicle is described. The hitch coupling assembly includes a receiver tube and a receiver wedge assembly. The receiver tube and the receiver wedge assembly are coupled to each other using a tightening bolt. The receiver tube, receiver wedge assembly, and tightening bolt are then inserted into a hitch receiver of a vehicle, and the tightening bolt is tightened to couple the hitch coupling assembly to the hitch receiver. A receiver lock can be used to lock the hitch coupling assembly into the hitch receiver. An accessory rack or other accessory that is coupled to the hitch coupling assembly is coupled to the hitch receiver and the vehicle by coupling the hitch coupling assembly to the hitch receiver.

Abstract: An accessory rack for a vehicle couples to the hitch receiver of a vehicle to carry accessories on the vehicle. The accessory rack includes a base rack, a hitch coupling assembly, a first swing arm assembly and a second swing arm assembly. The first and second swing arm assemblies are hingedly and removably coupled to the base rack. The first and second swing arm assemblies swing out from the center of the base rack using hinges at the outer ends of the base rack. The first and the second swing arm assemblies carry accessory racks for different types of accessories. The base rack is coupled to the hitch coupling assembly. The hitch coupling assembly couples the base rack and the first and second swing arm assemblies to the hitch receiver of the vehicle.
