Lund's TrailRunner Running Boards offer maximum durability, performing under the most rugged conditions. The wide step provides sure footing in any weather, and four available lengths mean a sure fit for trucks and SUVs. Available in an industrial diamond-plate aluminum design with brite finish, and in heavy-duty extruded designs with brite or black finishes. Constructed from heavy duty, yet lightweight aluminum, these boards feature molded, adjustable end caps for a custom fit appearance. These running boards come pre-assembled and install easily using the Multi-Fit EZ Bracket Mounting Kit (sold separately). The mounting brackets are made to custom fit your specific truck or SUV's make and model, providing added safety and convenience.
