Rev Boxes are designed to enhance the rev limiter from 750-1000 rpm. By allowing the rpm of the machine to go over its normal low setting allowing the engines to build the actual horsepower that they were designed for. By moving the rev limit up we have been able to pick up 1-3 hp depending on the model. These are the same ATV Rev Box as Big Gun, White Brothers and Advantage use. Just a diffrent sticker
