This stick on bumper from ProWatercraft Racing has been race tested and proven. Our bumper shape offers improved grip in the turns and trust worthy adhesion for longevity. The Half-round shape gives the sharp edge bond flange a smoother shape, which allows water to roll around the corner. Believe it or not, when you can control the water you can improve handling. High quality, self adhesive, rubber bumpers. Comes as one piece, 18′ long.
