FSD Supply Co., developed by Kevin Kubinak, is a free lifestyle application available on the iPhone platform. Full Send Diesel, the company behind the app, prides itself on offering high-quality performance parts at competitive prices with swift shipping. Founded in 2018 by a former United States Marine, FSD Supply Co. originated from the founder's dissatisfaction with existing truck modification products, leading to the creation of their own parts for public consumption.

Full Send Diesel's operations have expanded significantly from a modest barracks room setup to a substantial 44’x88’ facility in Lewisburg, Pennsylvania. Specializing in diesel aftermarket parts for Cummins, Duramax, and Powerstroke vehicles, FSD Supply Co. has rapidly gained popularity, boasting a wide network of dealers across the USA and Canada, including well-known platforms like Xdp.com and Puredieselpower.com.
