The R&D 1 Degree Reduction Nozzle Wedge Kit for the new KAWASAKI ULTRA 300 will add quicker acceleration and top speed performance as well as allow the ULTRA 300sâ€™ bow to ride slightly higher which will significantly reduce bow spray promoting a much dryer ride. Extensive testing has led our development team to wedge the reduction nozzle up 1 full degree which will inexpensively give the ULTRA 300 better handling everywhere and provide a boost of up to 1 mph in top speed performance. The billet aluminum CNC machined 1 degree reduction nozzle wedge kit was specifically designed to work without compromising or removing the O.E.M. reverse gate or nozzle trim. The R&D Pump Wedge Kit comes complete with all the necessary hardware and instructions for easy installation. A smoother, more enjoyable, dryer, faster ride! Only from R&D!
