Tuxtreme is a new generation of running boards designed to look and feel different. Most running boards in the market are round or oval. Tuxtreme's flat profile design is clean and modern - giving your truck a truly distinct look. The Tuxtreme's low profile design is so unique even your dealer will be asking you where you got them from. The Tuxtreme's aircraft grade aluminum and heavy duty brackets can support up to 500 lbs without bending. Sturdy, comfortable, and durable. Its ridged high grip tread top provides a solid, non slip and continuous footing along the entire length of the bar. Which means these running boards will give you unparalleled access to your truck's windshield, roof top and truck bed.
