The result of a three-way partnership between our friends at RealWheels, IMI, and Eco Flaps, this kit contains everything a professional driver needs to improve their gas mileage while keeping their truck’s profile sleek and aerodynamic. Eco Flaps’ patented high-impact nylon mud flaps have been recognized as an industry-leading advancement in the move toward improved fuel efficiency, reduced truck maintenance, and safer traveling conditions on the highway. The only splash guards certified by the EPA’s SmartWay standards— their molded, wing-shaped channels move air and water through their surface, reducing road spray and drag as they pay for themselves! Just as vital, Equal Flexx provides a wheel-balancing medium that increases fuel economy and reduces tire-related operating costs by absorbing damaging vibrations. The unique Flexx material is specially designed to absorb this energy, meaning less wear-and-tear on your wheels and frame, more even tread wear, longer tire lifespan, and a noticeably smoother ride for the person in the driver's seat. Of course, we can't forget RealWheels' twist-and-lock aerodynamic hubcaps, keeping all these cooperating systems in check and your rig looking great while they do!
