About the shop
Small shop attention with serious performance knowledge.
This is not a drop-your-keys-and-hope-for-the-best shop. Foulks Performance is built around direct communication, hands-on work, and engines that have to prove themselves under load.
Whether you are piecing together a drag car, bringing a diesel back to life, or trying to make a daily driver dependable again, the goal is the same: fix the real problem, build it correctly, and keep you informed the whole way through.
- Clear owner communication instead of front-desk guesswork
- Options and pricing discussed before the work moves forward
- Real range across gas, diesel, street, strip, and swap jobs

How it works
A better process lowers anxiety before the first phone call.
Tell the shop what you have
Share the vehicle, symptoms, current setup, and what you are trying to fix or build.
Get options and expectations
Discuss likely paths, parts or repair direction, and what makes sense for your budget and goals.
Approve the work
Once the direction is clear, the job moves forward with fewer surprises and better communication.
Stay updated through the build
Customers are kept in the loop instead of wondering what is happening to the vehicle.
