Richard buys a ’78 Cutlass so Aaron can build Gas Monkey’s first ever lowrider, he only to discover that Aaron’s plan to create custom hydraulics is something he’s never attempted before.

As Richard heads to Houston to check out Gas Monkey’s top fuel NHRA dragster do some racing, the Monkeys need to do some racing of their own to finish a custom lowrider paint job on the ’78 Cutlass in time for the car’s debut.
