This BackRack low-profile tonneau hardware kit replaces standard railmount hardware and lets a toolbox sit flush against the BackRack, eliminating the gap without drilling. Designed for 2019 and newer Silverado and Sierra models, the kit ships in a standard 21-inch format to support straightforward, low-profile toolbox installations and a cleaner bed layout.
