This adapter kit is used to convert your Front Runner Foot Rail Mounted Slimline II Roof Rack into a Load Bar solution.
If you'd like to take the Slimline II Roof Rack Tray off of the Front Runner Foot Rails fitted to your vehicle and install Load Bars onto it instead, these adapters bolt onto the two fitment points that would alternatively fit onto the Roof Rack Tray and creates a slot for Load Bars to bolt onto it in the center.
Front Runner Load Bars are sold separately and are available in different widths to suit a wide variety of vehicles.
This set comes with four adapters, two for the right hand side's foot rails and another two for the left hand side's foot rails. This kit includes all installation hardware needed to make the conversion.
