The BackRack wide-top tonneau hardware kit for 2019+ Silverado and Sierra models replaces standard railmount hardware to allow toolbox installation flush against the BackRack, eliminating the gap between toolbox and rack. It permits toolbox mounting without drilling into the truck bed and is sized for the standard 21-inch toolbox footprint to deliver a clean, low-profile installation.
