Their prices are really good Their prices are really good, and they only seem to carry quality stuff. I placed an order one evening and included a request to verify I'd ordered the correct part. First thing the next morning Ryan called me, and the correct parts were on the way same day.

Allied 105a Lithium Battery- Great Service!! Jordan and Ryan were extremely helpful, polite and knowledgeable. They accommodated my warehouse pickup which I greatly appreciated.

Rear seat upgrade rear seat kit, grab rail, and seat covers all arrived as advertised. Decal had peeled off of the drivers side rear seat frame, but wasn't that big of a deal to me. Might want to order the seat belt kit, but I'm gonna wait and see how I like it with out for a season.

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.

Knowledge, trust and very reputable There are so many choices when purchasing accessories for golf carts. In my case, I purchased an old DS cart with the intention of rebuilding it from the ground up. It's my first cart and in many ways, I didn't know what I was getting into. I am very detailed and I needed someone who knew their products and golf carts vs someone who just sells parts. I called Jordan and Ryan at least a dozen times, asking questions and asking their opinion about what specific parts to buy. They knew the filament of each part and they were able to give me exactly the information I needed before pulling the trigger. The shipping was also right on point with what they promised. With all the options out there, Extreme Kartz is my trusted source for all my cart needs. Trust me, I have tried other vendors and have had very bad experiences. These guys can guide you to ensure you purchase the right parts.
