Jordon and Extreme Kartz were outstanding Jordon was your sale rep with whom I worked. Jordon was quick to respond to a number of questions that I presented him. I not only conversed with him via email but also via telephone. He was also very pleasant when talking on the phone. If he didn't have answers immediately he always got back to me in a timely manner. In my view you have an excellent employee in Jordon who represents Extreme Kartz extremely well. My order was promptly shipped and received in a very timely manner. Fully recommend Extreme Kartz.

Bought the Navitas 600 amp Bought the Navitas 600 amp, and 5k engine swap kit my 2010 Club Car Precedent. Prior to kit installation my cart had a max speed of 17mph. After installation of kit, my top speed is 33 mph, nearly a 100% improvement. Support from Ryan Hart was excellent. Instructions are weak. But with a video on Navitas’s website, I was able to complete the install with a minimal amount of wasted time. Extreme Karts - I would buy from them again. Worthy of 5 star rating.

The price was very competitive … The price was very competitive with other companies. The conversion kit for my cart was top of the line. I had zero problems swapping the lead batteries out. The staff was very helpful in answering all my questions about the install kit that I was looking at buying. After install the cart performance is amazing and it is everything I have hoped it would be. Now will have to wait and see what the long term uses will be.
