Who We Are

Three Generations of Craftsmanship

The Duncan Brothers have been building cars privately for 70 years, beginning with brothers Leonard & Barnett Lee Duncan in 1949, followed by Leonard’s sons Rick & Randy Duncan. Now, the 3rd generation of brothers, Aaron & Joey Duncan, are taking it to the next level by offering their custom builds to the public.

Wanna See Myself Get Through Tonight

The long nights, the long road, and the mistakes along the way are a part of this life that isn't exactly spoken of too much. You see the shiny cars, the posed for pictures, and see the people thinking how nice it all must be. The grind is taxing, but the people you work with make the grind worth it. The laughs are the fuel that get you through the long nights.

The most addictive feeling on the planet is the person you do a build for being speechless and overcome with joy when you finish their dream. We've been lucky to have so many friends and memories on this journey.

This video is dedicated to our crew, our headaches, our colleagues, our family, our friends, our customers, and all the people that have made this dream a reality for us.

Thank you all!

PS - There will be more blood and sweat in the future. We're not even tired yet.
