Our 33 years of "Quality & Performance" continues with more belt drive and clutch choices than ever before. From the massive 3-1/2" wide Brute Force™ with carbon fiber guards and outer bearing supports, to the 3" wide Brute IV Extreme™ which retails as low as $1295, dependable power transmission continues to be the exclusive domain of Primo Belt Drives, and we continue to 'smoke the competition'! Primo's latest innovation is the all new Direct Drive™ 3 1/2 inch wide open primary belt system which relocates the starter to the area between the front and rear pulleys and the ring gear to the area behind the front pulley, giving a builder the latitude to further drop seat height as well as turn over a high compression motor with little effort.
