You will receive 4 brake rotors to replace the front and rear brakes on the following: 2015 Arctic Cat Prowler 700 HDX XT. The MudRat Rotor is a solid rotor design, keeping mud and other abrasive materials from filling in vent holes and prematurely wearing your brake pads. This rotor is designed to be used in 90% mud grade or higher. This new rotor design has been tested over several years to extend the life of brake pads in extreme mud, and other intense conditions. Race-Driven has observed that many models, especially the Can-Am Gen 2 model, factory stock pads do not hold up while riding in mud, regardless of the type of vented rotor. If you are an aggressive mud rider this is the rotor for you. Race-Driven is committed to bringing the highest quality products to all riders at an affordable price.
