For over four decades, Trinity Racing has been the name synonymous with power, precision, and performance in the off-road world. What started as a small garage in Garden Grove, California with a $3,000 investment has evolved into one of the industry’s most respected names in high-performance ATV and UTV tuning — trusted by racers, builders, and weekend warriors worldwide.

🔥 From the Desert to the Stadium

Founder Harry McDermott turned his passion for racing into a lifelong pursuit of horsepower. From running SCORE-International races in Baja to pioneering modern quad performance tuning, Harry and theTrinity team built their legacy the hard way — by testing every setup themselves.

That same spirit lives on in Trinity’s race program today. Back in 2003, the Trinity Racing Team made waves at the SFX Pro Quad Stadium Series in Anaheim. Riders Jeremy Schell and Cory Hinsz piloted Trinity-built Z440 machines through the whoops and mud at Edison Field, backed by a sold-out crowd and a dedicated pit crew. Even after a tough crash that took Schell out of contention, the team’s grit and determination set the tone for everything Trinity still stands for:

⚙️ Inside Trinity’s Performance Lab

Today, Trinity Racing operates out of a 12,000 sq.ft. facility packed with serious hardware — including a CNC manufacturing shop, full engine machine shop, and SuperFlow CycleDyn Dynamometer. Every product is tested, tuned, and proven before it leaves the building.

Harry’s “Total Tune” philosophy drives every project: each exhaust system, cylinder, and clutch kit is engineered to deliver the broadest, most usable powerband possible — because it’s not just about peak numbers, it’s about performance that lasts.

“You might find parts that gain 2% more on paper, but once you tune it right, add race gas, port the motor, or raise compression — Trinity’s parts outperform them all.”
