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 300s 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!
