U.M.I. Racing

UMI Racing started in 1987 in Scottsdale, Arizona primarily as a CNC machine shop. Our first products were watercraft billet machined steering systems along with other aftermarket handling components. These parts are still used by the top watercraft racers and freestyle riders in the world, as well as a number of OEM's. UMI has dominated the personal watercraft market for the last ten years with our unsurpassed quality and service. UMI also manufactures a complete line of Harley-Davidson aftermarket foot controls and billet accessories which are used by the top Harley aftermarket builders. UMI also manufactures a line of aftermarket sport ATV parts for most major brands. Over the last two years UMI has been developing an off-road motor package utilizing the General Motors Vortec LS-1, LS-6, and 6.0 liter Generation 3 motors. These motors have taken Mark Miller racing to two consecutive Baja 500 victories in the trophy truck class, a 2003 Baja 1000 first place trophy truck and a second place overall. UMI exclusively uses the Delphi System 4 engine management systems. These motors are an excellent choice for all V-8 off-road vehicles ranging from 365 to 500 horse power.
