A balanced engine is an efficient unit that delivers more power and better mileage. It will run smoother and lasts longer due to less stress on the internal components. The Winona Van Norman XLX Balancer uses sophisticated electronics but remains easy to operate. The XLX is designed to be able to balance work pieces inboard and outboard. Because the XLX includes 5 potentiometers it can be used to balance more than just crankshafts.
