Does your heavy-duty truck have a 2.5" or 3" hitch receiver? At 1UP USA, we can help with that. Sleeve adapters included with these receivers don't work with our racks because of the added play and the expander ball design.

We offer adapters — made from steel angle with a black powder-coat finish — designed to sit on the bottom right-hand corner of the receiver. It allows the expander ball to function properly in the top left. A threaded hole on the right side of the adapter acts as a stop when installing a rack on a vehicle.

It can be removed for the 2.5" Hitch Adapter, allowing the locking security pin — included with each rack — to be used. For the 3" Hitch Adapter, the set screw is left in and acts as a stop because the included lock is not compatible. Hitch adapters are available on the Hitch Accessories page of our website.
