SUMO Parts
Engineering. Design. Performance.
SUMO Parts has been designing and building products since 2010.
We are not just a storefront — we are a full engineering and manufacturing division with capabilities in:
- Product design & development
- 3D scanning & CAD modeling
- Prototype fabrication
- Low-volume builds through full production
Our parts are used every day in autocross, rally, road racing, off-road racing, and drag racing.
You may not know it, but you have probably used our products or designs under a different name — SUMO produces components for many brands and private-label partners.
What We Do
✔ Design and engineering of new products
✔ Reverse engineering of existing parts
✔ Prototype builds & testing
✔ Low-volume manufacturing
✔ Scaled production
We offer products under the SUMO brand, and also provide private label and co-development programs for industry partners.

Our locations in Colorado, USA and Batemans Bay, Australia allow us to support both hemispheres and deliver quickly to customers.
