Founded by Seth Newhart—a true diesel junkie who built his dream truck from the ground up—Diesel Royalty started as a passion project. It all began in the garage, at shows, and on the track. What started with one custom ride turned into a full-blown movement.
Seth didn’t just build trucks. He built respect in the scene. And now? He’s building apparel that speaks the same language.

No paper-thin tees or cheap prints here. We only roll with heavyweight quality and premium feel.
We care where it’s from. That’s why our apparel and upcoming detailing products are built right here at home.
Everything we sell has seen grease, heat, and horsepower. It’s built for real life, not just the ‘Gram.
From burnout pits to diner runs, our apparel’s designed for wherever the diesel life takes you.
Every design comes from real track and show experience. Seth knows what you need, because he’s lived it.
Real results. No fluff. Just solid formulas that earn their place in your shop.
