After losing to the 405 during the last Mega Race, Richard Rawlings wants a rematch and this time, he's going after current #1, Ryan Martin. The guys at Misfit Garage also callout Farmtruck and AZN for a race of their own, where they each build a new car.
The Gas Monkeys work to make sure their chassis will let the car drive straight, but weather prevents them from making any good test passes. Ryan and his team head to Tucson to test the car in Arizona's warmer climate, but must work through some trials.
The Misfits start their build but tempers flare when an argument breaks out, threatening to stall the build completely. Farmtruck and AZN work on transforming the Gonorail into a functioning vehicle, but learn that this build will take extra work.
Farmtruck and AZN and the Misfits complete their builds and make some test hits, but teams struggle with technical issues that must be corrected. Ryan arrives in Phoenix along with some fellow 405 racers while the Gas Monkey crew heads to Arizona to race.
It's finally time for Mega Race 2, and that means that the racers from Street Outlaws, Fast N Loud, and Misfit Garage are all in Arizona for the big race. It's Oklahoma vs. Texas, and these guys will do anything to win.
