You demand the best and we're here to give it to you. Every piece of the Big Boy was strategically designed and built with the most premier parts, from being precision laser-cut steel to the black wrinkle powder coated for protection.

SUPPORT SMALL BUSINESS
Vyper was founded by the Rusch Brothers back in 2020 with a determination to manufacture the highest quality products and create the most American jobs they could.
Growing up in the garage industry, the Rusch Brother's saw an increasing number of products being brought in from overseas. Being proud American's, they were determined to change this.
