This custom Corvette is a head-turner wherever it goes.
It recently rolled into US 12 Speed & Custom for a clutch replacement and some general maintenance to keep it driving as flawlessly as it looks.
Whether you need routine maintenance, repairs, or a complete custom build, we've got you covered.

🏁 Custom fabrication in progress on this Fab-Friday!
These custom fabricated "heat shield bubbles" are just for the twin turbos, one of the many custom touches going into this 52 Chevy Drag Week truck.
That's how we do it at US 12 Speed & Custom👊
More to come on this project...

🇺🇸 Happy 250th Birthday, America! 🇺🇸
For 250 years, America has been full throttle, burning rubber, pushing limits, and proving that bigger really is better.
Here's to freedom, horsepower, and celebrating the greatest country on earth.
Have a safe and happy Fourth of July and keep the fireworks in the sky... not under the hood. 💥

Happy Father’s Day to all the dads who taught us the value of hard work, horsepower, and family.

You know you're deep into a project when the fuel tank is also a fabrication project.
🔥
Custom methanol fuel cell built specifically for this chassis and application. It's not the flashy part everyone notices, but it's one of the pieces that helps get this beast down the track.
And yes, it holds more than hopes and dreams.😜

Some people see a pile of parts.
We see the beginning of a really bad decision for rear tires. 🔥
We're building a custom set of stainless headers for this Ford 427 SOHC, and let's just say it's going to make all the right noises when it's finished.
Stay tuned...

We spend our days building, fabricating, adding horsepower, and pushing limits…
but today, we take a step back.
Memorial Day is about remembering the men and women who gave their lives for this country and the freedom we get to live every day.
This Memorial Day, we honor those who made it all possible.🇺🇸
