This BackRack low-profile tonneau hardware kit is made to replace standard railmount hardware and allows a toolbox to be installed flush against the BackRack without drilling. Specified for 2019 and newer Silverado and Sierra HD trucks only, the kit uses a standard 21-inch layout to eliminate the gap between toolbox and rack, enabling a cleaner, low-profile bed setup for heavy-duty pickups.
