Custom Fabrication

Custom automotive fabrication for American made classics

Every serious build reaches a point where off-the-shelf parts just won’t cut it. We create custom fabricated components that solve fitment challenges, maximize performance, and bring unique visions to life. From headers to turbo kits and roll cages, our shop is your go-to source for precision metalwork tailored to American engines.

Engineered solutions for serious performance builds

We specialize in building custom components that integrate seamlessly into Ford, Chevy, and Mopar projects. Whether it’s a turbo manifold designed to fit tight engine bays, or unique exhaust routing for a supercharged setup, our solutions are engineered for durability, flow, and reliability.

Fabrication capabilities that set us apart

  • Custom exhaust headers and turbo manifolds
  • Intercooler piping and intake fabrication
  • Roll cages and chassis reinforcement

  • Fuel systems and catch can setups
  • Custom sheet metal fabrication

Our TIG and MIG welding services ensure precision welds that look as good as they perform.

Fabrication for street, strip, or track

Each piece we build considers the real-world conditions of your car’s purpose. Street cars require fitment around factory accessories and comfort features. Race cars demand maximum flow, weight savings, and compliance with safety regulations. We deliver both.

Solving unique fitment and clearance challenges

Modern power upgrades like big turbos, superchargers, or LS swaps often mean tight engine bays and new obstacles. We measure, design, and fabricate components that eliminate interference, ensuring proper clearances without sacrificing performance or reliability.

Materials we work with

We fabricate with premium materials, including stainless steel, mild steel, aluminum, and occasionally titanium. Each project is chosen for the best balance of strength, weight, and heat resistance for your application.
