In-House CNC Machining & Fabrication
We don’t outsource critical work. Every part, from complex suspension brackets to custom driveline components, gets cut right here in Mooresville, NC. Our 3-axis and 5-axis CNC machining centers deliver tight tolerances, clean finishes, and exact repeatability. If it needs to be right the first time, this is where it happens.
We’ve turned more than a few rough concepts into race-ready parts. Fixtures are built in-house, tools are prepped to spec, and every setup is checked twice before the cutters hit the material.

Custom Part Design & Prototyping
Sometimes a build starts with bare chassis steel or a sketch on paper. Other times, a part needs revision to sharpen performance or meet new regulations. We handle both.
Our engineers use practical know-how rooted in real race experience. We’ll take your sketch, old part, or CAD file, then iterate through design, material selection, and test-fit until it’s ready for production or track use. No fluff, no guesswork.

Finishing, Inspection & Quality Assurance
Machining is only one piece of the job. After a part comes off the mill or lathe, we deburr, inspect, surface-prep, and apply any coatings or finishing work needed to prepare it for real-world abuse.
Each part leaves with a final inspection. We check fitment, dimensions, and finish under the same mindset a race team runs with; if it doesn’t meet our standards, it doesn’t leave the shop.

What people say
FAQs
What size or volume can you handle?
From single-part prototypes to small batch runs, we’re equipped for both. Complexity and tolerance, not quantity, are what matter most.
What materials can you machine?
Common race-grade metals: steel, chromoly, aluminum alloys, and materials chosen to meet each job’s specific strength, weight, or wear requirements.
Can you ship parts outside the region?
Yes. While we serve local teams and shops, we can package and ship nationwide when required.
Do you offer material sourcing and fabrication assistance?
We do. Need raw stock, heat treatment, or finish work? We’ve got connections and can guide you from start to finish.
