We build and modify cars and trucks with a point of view—from 70s and 80s icons to late-model performance and one-off machines. Every project begins with the owner, the purpose and the right plan.

Custom car builders in Scottsdale
Roadrunner Customs is an invite-only custom car and truck shop in Scottsdale, Arizona. We build and modify hot rods, muscle cars, restomods, race cars, vintage classics and late-model performance vehicles for owners who want a direct relationship with the people doing the work.
Our Scottsdale shop handles performance and drivetrain work, suspension and brakes, electrical systems, race preparation and one-off custom fabrication in partnership with RTC Fabrication. We intentionally take on a small number of projects so every build gets a clear plan, careful workmanship and the attention it deserves.

The Roadrunner standard
Clean lines. Correct stance. Smart engineering. We sweat the details that turn a collection of parts into one complete vehicle.
