Aggressive Style Meets Everyday Functionality: Upgrade your truck's look and performance with Rough Country's AC2 Running Boards. These premium cab-length steps combine rugged durability, modern styling, and practical convenience in one sleek package. Built for Strength and Style: Crafted from heavy-duty, one-piece steel, the AC2 Running Boards deliver maximum strength and rigidity for long-lasting performance. A black powder-coated finish offers superior corrosion resistance, shielding against rust, wear, and harsh weather. Maximum Accessibility: Easily enter and exit your truck thanks to the wide step surface and lowered profile, perfect for lifted vehicles or daily drivers alike. The cab-length design offers full coverage and enhances your truck's side profile with clean, aggressive lines. Integrated Illumination: Stay visible and stand out with built-in LED lighting. Customizable LED Output lets you choose between amber or white via an internal switch, while Automatic Activation engages the lights when your door opens, thanks to a built-in magnetic sensor. Enhanced Protection and Clean Looks: The AC2 boards also provide a barrier against road debris, rock chips, and mud while covering up exposed frame components for a seamless, finished appearance. Body Lift Compatible: No need to worry about aftermarket modifications, these boards are fully compatible with or without a body lift, ensuring a perfect fit across various setups.
