      Customize Your Truck. Give your Sierra's bed a custom look with these exclusive Diamond Donut adapters. The black finish of the adapters accents your truck's trim, while simultaneously providing excellent functionality by simplifying attachment of the bed's 1-3/4 in. diameter side rails to a crossover kind of toolbox in the bed.

      Robust Adapters. The pair of adapters is made of anti-rust, stable CNC billet aluminum. Manufacturer backs the Diamond Donuts with a lifetime warranty, giving you confidence they will function seamlessly and look great for a long time to come. The two foam gaskets in the kit help to prevent water from seeping into the toolbox at the points of attachment.

      Simpler to Install. These Diamond Donuts enable the side trails to slide into them in front of the toolbox, without the hassle of trying to mount front stake pockets like you would have to with other systems. Just drill into the toolbox, attach the donuts, and cut the side rails to slip into the unique adapters. The Diamond Donuts fit securely in place using the included 5/32 in. set screws. The kit also has the flat washers and bolts necessary for quick installation.

      Application. These Black Diamond Donuts fit 1-3/4 in. diameter side rails and are a superb choice for all 2007 to 2021 GMC Sierras.
