The 500 amp Curtis controller packs quite a bit of performance for your EZGO in a tiny package. Who knew something this little could give you a torque increase of over 50-percent? Buggies Unlimited did, heck, their techs map these things personally to make sure your EZGO gets the most response when you press the pedal. What if you are looking for something a little more personal? Call in to place the order and ask to have it programmed for your needs, free of charge. Just another reason we are the best vendor of quality aftermarket golf cart products.This golf cart 500 amp beast cannot stand alone; you want to consider replacing the motor, but an absolute requirement when increasing the drive system's amperage is a new EZGO solenoid, forward and reverse, and cables at the very least. Without these, you are not only endangering all of the stock components of the drive system, but that brand new controller is also going to run hot and fail. Don't let any of that happen; call us first.
