GMC Sierra 3500 HD Nerf Step – N-Fab – Wheel-to-Wheel with Bed Access – Textured Black – 2020–2025. Sturdy, purpose-built nerf bars that add confident footing and practical bed access.
Built from heavy-gauge .084-wall steel and welded into a rigid one-piece assembly, this N-Fab system runs wheel-to-wheel with a dedicated bed-access step on each side. The 3 in. main tube tucks high to help hide the frame and deflect road debris while preserving clearance. Each bar is zinc-coated inside and out, then finished in a durable textured black powder coat for long-term corrosion resistance. Fully welded step pads deliver a solid, non-slip platform you can trust.
