2 Inch Hitch Riser - CLICK THIS LINK

A hitch riser may be necessary if your rack is too high or too low. They are easy to install and can be purchased in varying heights. Often a 2 inch rise is all that is necessary to give you the clearance you need. However, if for instance you drive a very tall vehicle, you may find that you need to lower the rack. You can do this by simply turning the hitch riser upside down. Depending on your needs, you may need a hitch riser that offers a bigger drop.
