GMC Sierra 3500 Bed Rails & Caps

Along the bed sides, GMC Sierra 3500 Bed Rails & Caps add a finished look while helping frame the truck bed with a clean, rugged edge. They can also cover exposed rails and give the rear of the truck a more complete appearance.

Different styles can change the look a lot, from simple polished rails to low-profile caps that blend in smoothly. Material, finish, and overall shape matter most when matching the truck’s trim and the rest of the exterior.

More exterior pieces can round out the look, including GMC Sierra 3500 Exterior and GMC Sierra 3500 Grilles. Model-specific options are also available through 2020-2026 GMC Sierra 3500 Bed Rails & Caps.
