A set of Pickup Bed Load Bars used to transport gear over the bed of your Chevrolet Silverado/GMC Sierra 1500/2500/3500 w/ReTrax XR rails. This low profile solution includes 3 x 1575mm Load Bars and 6 Pickup Roll Top Leg Mounts that fit into the existing ReTrax XR rails. The Load Bars are mounted via Pickup Roll Top Load Mounts that bolt directly into the existing ReTrax XR rails. Allows for gear to be mounted above the pickup’s load bed. The load bed retains its load-carrying ability, while the drop down door functions as usual. Uses the same strong, corrosion-free aluminum slats found in Front Runner Racks. The sliding nut t-slots allow for quick fitting and removal of accessories and equipment on both the top and bottom of the slats. Made from steel and a durable, weather-resistant black powder coated aluminum. Includes all hardware, components and the installation guide needed to fit Load Bars on a vehicle. Note: If your Roll Top extrusion has a 6mm (0.24'') to 7mm (0.28'') slot opening, you may need RRAC962 for installation.
