Description
Custom Look. Customize your truck’s bed with these distinct Diamond Donut adapters. With a chrome finish, the pair matches the trim on your Sierra and has an attractive sheen, all while providing functionality by helping you install the bed’s side rails to a crossover type of toolbox in the truck bed.
Quality Construction. The two adapters are crafted from CNC billet aluminum to provide high stability and resist rust. The Diamond Donuts come with two foam gaskets to help keep water from leaking into the toolbox at the attachment points, as well as a Lifetime Warranty.
Ease of Installation. The donut adapters allow the 1-3/4-in. side rails to slide into them in front of the toolbox, rather than requiring more complex mounting in front stake pockets like other adapters. These Diamond Donuts are a cinch to install by drilling into the toolbox to attach the donuts and cutting the side rails to slip into the donuts. Secure the adapters in place with the included 5/32-in. set screws. The kit also comes with two 9/16-in. bolts and two flat washers necessary for fast installation.
Application. These Chrome Diamond Donuts are a great choice for all 2007 to 2026 GMC Sierras.
