The Stainless Steel Stallions are a biker gang of mutant horses appearing in Road Hogs. They control the northeastern town of Whinnie Mucca (formerly Winnemucca, Nevada) and are one last remaining, free biker gangs. They are opposed by the Road Hogs Gang and the two gangs have fought at least six times in the last five years. Rumor has it that they are somehow affiliated with a group called The Free Cattle who live far to the east. They have an estimated population of 6,000.
