The Stock Quarab (also known as 'Foundation Quarab') is a subtype of the Quarab breed. It usually carries more Quarter or Paint blood than Arabian blood.

Stock Quarabs are defined by their conformation, which has more stock-horse characteristics than Arabian ones. Their bodies are well-muscled, though they are still lighter compared to purebred Quarter and Paint horses.

Stock Quarabs come in all colors and patterns except for leopard. They stand between 14hh and 16.2hh.
