RealTruck also makes the FlushFit retractable tonneau covers, which share the same T-slot rail mounting, so a rack and a low-profile cover can run on the same truck.

The Elevate range runs from the lower-cost Base Truck Rack up to the full Elevate Truck Rack, both built on Elevate TS Rails, with bolt-on accessories like side bars, cargo baskets, and bike and kayak carriers. Top picks: Elevate Truck Rack for the full over-bed rack, Elevate Base Truck Rack for a lower-cost setup, and Elevate TS Rails as the rail foundation that also lets a FlushFit cover share the bed.

Because the Elevate rack and RealTruck's FlushFit retractable covers share the same T-slot rails, you can run the rack and a low-profile cover on the GMC Sierra 3500 at the same time. Every piece ships with the manufacturer warranty, and a fitment check is free before you buy.
