STONE MASTER KART PRODUCTS are a result of quality workmanship and innovation.  Made in the USA with a strong emphasis on ease of installation and unparalleled performance, STONE MASTER KART PRODUCTS is a division of STONE MASTER KART PRODUCTS, LLC of Grand Junction, Colorado .  Bill and Garrick Stone are founders and administrators of the company.  Both were inspired by their personal interest and involvement in karting to design and fabricate Kart components for their own use.  Karters and local race events were interested and impressed with the quality and functionality of the components.  This interest motivated them to design and manufacture their seat struts and throttle cable grippers for the Kart and Kart racing markets.  All Karters can benefit from these products – from shifters to TAG to Juniors and comers.
