I appreciate the recommendations made to help me select the best lithium conversion for my cart. Provided insights for pros and cons of each vendors offering. Delivery was quick and technical support got me to the finish line! Cart runs great now!

I was looking to convert my 2010 Club Cart Precedent over to Lithium Ion. My main concern was to pick a supplier that could help guide me through this process. Number one on my wants was a high quality package that would not be a head ache down the road. I also wanted a supplier that could provide help if I had questions. I picked Extreme Kartz and was very pleased with their recommended ECO Bundle. My install went very well.

Extreme Kartz knows nothing about golf carts. They are just a storefront with no inventory or golf cart knowledge. There are a number of very knowledgeable golf cart part sources so save yourself wasted time and order from one of the reputable sources.

We’re sorry to hear you feel this way and appreciate the opportunity to respond. Extreme Kartz is not simply a “storefront.” We have a dedicated team of golf cart specialists working across multiple states whose full-time focus is golf carts and performance upgrades. We also operate a large warehouse in Tyrone, Georgia. Like every major online golf cart retailer, we cannot physically stock every single part available on the market — which is why we partner with industry-leading distributors such as Nivel and Red Hawk to ensure fast delivery and broad product availability for our customers. Our team continuously trains to stay current on all makes, models, and upgrades, which has earned us recognition as one of America’s leading destinations for golf cart upgrades — not just for our product selection, but for the technical support we provide before and after purchase. Regarding your specific order, our records show that you worked closely with one of our technicians for over a week. During that time, he clearly explained that the dash you ordered required minor modifications — specifically removing small plastic nubs under the factory dash for proper fitment. This information was verified directly with the manufacturer’s technical team to ensure accuracy. When you decided you did not want to make those modifications, we immediately provided you with a prepaid return label and waived both return shipping and any restocking fees — despite the fact that the product was not defective. Customer satisfaction and technical expertise are core values for us, which is why we went above and beyond to assist you throughout the process. We’re genuinely disappointed to hear that your experience did not reflect the level of service we strive to provide. We wish you the best moving forward and remain here if you ever need assistance in the future.

No tracking number. I tried SHOP, too difficult. Should be ASAP like most sellers. $1500+ order, feeling uncomfortable with no follow up.

Thanks for the positive review! You are always able to email us, call us, text us, or check on our website on your order to access your tracking number! We can't wait to help you in the future!

Ryan was very knowledgeable and helped me order the right equipment that was best for my Yamaha D2 I went with Bolt Energy kit All was for the most part plug and play. The only thing i had to do is upsize ring terminals so they will fit the much larger studs on solenoid

Extreme Kartz was extremely helpful and great to work with. Their responses were very timely and they took the time to investigate my battery conversion questions.
