This BackRack low-profile tonneau hardware kit replaces standard railmount hardware so a toolbox can be mounted flush against the BackRack, eliminating the gap without drilling into the bed. Specified for 2014–2018 Silverado and Sierra models, the kit comes in a standard 21-inch configuration with an optional 31-inch arrangement to suit different toolbox sizes and installation preferences.
