I have now installed 4 conversion kits and have zero issues. The staff has been incredible and go about and beyond. I was having an issue after installing one and the staff was very helpful and i was able to trace the issue down to the Modular.

Thanks for the kind words Kelle! It is always a pleasure working with you and we can't wait to help you with future builds!
I ordered a Bolt 48v lithium battery from Extreme Kartz after many hours of reading through their Lithium battery comparisons which were a huge help and ultimately the reason I ordered through them, because it goes above and beyond what other online retailers are doing and the lithium battery rabbit hole can be a big one to fall into. Shipping was quick, communication was great and the product arrived just as advertised. I will definitely use Extreme Kartz again!!

Excellent products. Just finished upgrading my Club Car batteries to the Bedrock 105AH Lithium Battery. The products came packaged very neat and organized. The battery was shipped in a very nice wooden crate. Installation directions were spot on. Looking forward to some summer cruising.

I initially was having a rough experience with my purchases but after contacting the customer support team, I’m more than satisfied with my experience. I enrolled in the dealer program and can’t wait to do future business with them. Definitely recommend to others.

The upgrade installed on my 2014 Club Cart provided by Extreme Kartz was exceptional! One of the easiest installs I’ve ever performed ( minus the awkward position in lifting a 52lb motor)! All cables clearly identified a labeled and that with online instructions any novelist can complete this install in a day.
