Aftermarket parts are fantastic, trust us, we would know. But have you ever heard of an OEM upgrade? That means the stock producer of an item released a better version. The golf cart industry is no exception to this rule. When the Precedent model was released, it came with a 250-amp controller, which you can still get from your local dealer. However, Club Car quickly realized anything sub 300 amps would not cut it even on the golf course, and so was born the IQ 350-Amp Curtis Controller. One hundred additional amps in the same small package.Customers complained about the throttle not hitting hard enough. So, Club Car gave them a hammer of a controller as a response. If you are going to do something, you better do it right; that's why choosing Curtis as the producer was a no-brainer. From stock performance to high output units, no other manufacturer comes close to their level of quality.
