Collection: 2015-2019 GMC Sierra 3500HD Roof Racks

Every roof rack in this collection is fitment-verified for the 2014-2018 GMC Sierra 3500HD in regular, double, and crew cab. Stocked systems include Rhino-Rack Pioneer Platforms, Front Runner Slimline II, and Yakima LockNLoad, with ditch-mount towers, full-length platforms, and crossbars for tents, light bars, and Rotopax.

Do I need to drill the roof to install these racks? No -- the ditch-mount and factory-point systems we stock bolt to existing locations with zero drilling, preserving factory paint and sheet metal.

If it is listed here, it fits your Sierra 3500HD -- guaranteed.
