XTR Bottom Cross Bar Kit | Bed Rack Mounting Bars
Add more mounting bars to the bottom of your bed rack. The XTR Bottom Cross Bar Kit gives you additional crossbars down low, so you can carry more equipment and mount more plates. Each bar is solid 1530 Xtrusion in black powder-coat, adding T-slot mounting surface right where you need extra capacity. A practical structural addition to your bed rack accessories for anyone building out a bigger, more capable setup.
More crossbars mean more places to mount MOLLE plates, tools, slide-outs, and gear — whether you’re packing for an overland trip or loading up for the jobsite.
