The BackRack siderails for 1999–2016 Super Duty trucks with a 6.5 ft bed provide heavy-duty side protection and mounting for a 21-inch cross-bed toolbox. Built from heavy-gauge HRPO tube welded to an angular base that spans the bed, these rails pair with or without BackRack cab guards and accept cross-bed toolboxes. They install via stake-pocket bolts for a simple no-drill fit.
