You are here for a reason, and we want to help no matter what. What was it? Your neighbor beat you to the punch and got a controller for his cart, and now he beats you off the line? Put him in his place with the 36-Volt E-Z-GO TXT AMD Series Speed Motor. He will get whiplash with the speed you are going to pass him. You better get a rearview mirror as well so you can savor his face as you steadily pull away.This Speed Motor fits all 36-Volt Models that have series drive systems. It sports 4 HP @ 4,400 RPM, which is way more than the OEM unit. This is why it pays to shop aftermarket. Finally, we are looking at a 19 spline coupler, which can be used on EZGO or Yamaha. You know you want to call Buggies Unlimited and get one ordered today. Make it the last time you have to lose ground to anyone in your golf cart.
