About Us
Trinity Racing
Creating horsepower for off-road since 1978 – built for racers, weekend warriors, and anyone who wants more out of their UTV.
Our Story
Trinity Racing was founded in 1978 by performance builder Harry McDermott, known for creating high-output two-stroke motors for Yamaha Banshees and other ATVs. What started as a passion for going faster in the dunes and desert quickly turned into a trusted name in off-road performance.
As the industry evolved from quads to UTVs, so did we. Trinity Racing is now part of the Tolemar family, pairing decades of race heritage with serious manufacturing capability. Today, our focus is clear: build top-quality exhaust systems and performance components for the ATV and UTV market.
What We Build
Our product line is built around making your machine faster, stronger, and more fun to drive:
- Slip-on and full UTV exhaust systems
- Fuel management and tuning solutions
- Clutch kits and our World’s Best Drive Belts
- Radius rods, tie rods, and other chassis components
- Harnesses and select accessories
Since joining Tolemar, we’ve leaned into what we do best: performance parts that bolt on cleanly, sound incredible, and survive real abuse in the field.
Racing Is in Our DNA
We don’t just build parts in a vacuum – we test them where it matters. Trinity Racing supports 100+ racers across:
- SCORE International
- Best In The Desert
- WORCS
- GNCC
- Southern Bounty Series
- Southern Rock Racing Series
Our racers are on the podium week after week, helping us refine our products and prove their performance in real-world conditions – not just on a dyno.
Built In-House in California
One of the biggest advantages we have is our in-house manufacturing. At our Huntington Beach facility we use:
- CNC bending for precise tube work
- TIG welding by experienced fabricators
- CNC machining for brackets, flanges, and hardware
- Laser cutting and etching for consistent fit and finish
Nearly everything exhaust-related – from bent tube to welded assemblies – is made right here. Certain components, like our drive belts, are built with trusted partners to our specifications, but the core of what we do stays in-house.
Partners, Dealers & Riders
We’re proud to work with LeMans Corporation and to be distributed through Parts Unlimited and Drag Specialties, supporting some of the best dealers in the powersports industry.
