Receiver Hitch Adaptor - 4 Inch Extension

Vehicles with unique trunks, including truck tailgates and rear mounted spare tires, can improve rear access with a hitch adapter. By extending VelociRAX hitch racks back 4 inches and down 3.5 inches, most tailgates can fully open and spare tires can live freely on your vehicle while the rack is in the load position. Enjoy added space to the back of your vehicle while your hitch car rack is installed! Hitch adapters have a built-in anti-rattle system, also used with VelociRAX hitch racks, to eliminate rack movement. Installing a VelociRAX bike rack on other hitch adapters is not recommended due to our unique anti-rattle ability. Hitch Adaptors Include: Built-in proprietary anti-rattle system (use 17mm wrench to tighten and loosen) Double-layered, double-welded  Fully powder coated 2-inch size comes included with a 1/2-inch locking hitch pin, the 2.5-inch and 3-inch sizes can utilize standard 5/8-inch hitch pins Important - sizes refer to your hitch receiver (2-inch, 2.5-inch or 3-in
