Amsoil Shock Therapy (also known simply as Shock Therapy) was a custom off-road monster truck owned by Sudden Impact Racing out of Jefferson, Louisiana. It was sponsored by Amsoil, which served as a major sponsor for the team. Since its debut in 2008, the truck has been driven by various drivers, most notably Jon Zimmer, who drove from the start until his departure after the first quarter of 2012. The truck has also made two Monster Jam World Finals appearances under Zimmer.
