The Curtis Controller for Club Car and EZGO at Buggies Unlimited is what you need to get your caddie on the level you want. From the factory, we cannot expect much. The OEM design is to go from hole to hole and stop for a snack halfway through. They are not prepared to handle the punishment we sign them up for. Hell, some of the hills on your local course may give them too much trouble. If that is the case, upgrading a few of the base components may be just the answer you are looking for.We program this golf cart 500 amp controller for 0-5k throttle; the industry used these on vintage Club Car models and EZGO Marathons. You will need four gauge cables or thicker throughout the car for maximum performance, safety, and durability. You will also need a heavy-duty solenoid and forward and reverse switch. If you do not upgrade these things, they will fail in the long run. If you are looking for more control, you can adjust it with a handheld Curtis programmer, part number 1311-3301. This will allow you to use it for eight other throttle inputs.The installation of this EZGO and Club Car controller is not a problem. It is slightly different from the one that came on your stock golf cart from the factory, but it will wire up almost the same way. As a matter of fact, it will come with a diagram and a set of instructions. We leave nothing up to guesswork. Even if you still get stuck, we have a tech team ready with plungers in hand.You may have had some trouble finding a good vendor for EZGO parts in the past, but ok, no further. As a matter of fact, Buggies Unlimited has a vast selection of Club Car parts. However, we do not sacrifice quality in the process.
