Rock Slide Engineering's EZ Rack is a ultimate solution to store additional fuel or accessories. This is a single plate add on for the EZ Rack made of 11-gauge steel. We use a state-of-the-art automated powder coating system to acid etch the raw base material in preparation for the textured black topcoat. It will fit any size tire and the weight capacity is determined by what your tire carrier is rated. Our team recommends using the ROTOPAX fuel system and DLX fuel mount (RX-DLX-PM). The ROTOPAX base plate is included, but not to be used for EZ Rack installation. We recommend up to a 2.5-gallon pack.
