Engineered by SUMO.

Our designs have been manufactured under many names over the years.

You’ve probably installed or driven on our parts — even if the box didn’t say SUMO.

Across the industry, our engineering has powered products for multiple brands. Sometimes copied, sometimes imitated — but never matched.

The concept, the testing, the failure analysis, the reliability… all of that started here.

Anyone can duplicate a shape.

Not everyone can engineer performance.

If you want original engineering — not imitation — let’s talk about becoming a dealer or building something for your program.

Need help with a custom project?

SUMO is the engineering department most brands wish they had in-house.

If you need:

  • A factory part redesigned to survive real abuse
  • A custom bracket, spacer, mount, or assembly
  • A prototype turned into a production-ready part
  • Short-run or one-off manufacturing
  • Components 3D-scanned, reverse-engineered, or modeled
  • An idea taken from sketch → CAD → prototype → finished part

This is what we do every day.

We handle 3D scanning, CAD modeling, prototyping, machining, and production through our facilities in the U.S. and Australia — plus vetted global manufacturing partners. Everything is built to our specifications, our tolerances, and our quality standards.

Bring us the problem.

We’ll engineer, test, and build the solution.
