Battle of the Builders 2025: The Top 12 Take Over

Every November, the SEMA Show turns Las Vegas into the beating heart of the custom car world—but one showdown always steals the spotlight: the Battle of the Builders 2025. It’s the aftermarket industry’s ultimate test of skill, creativity, and innovation—where the best in the business fight for glory and the title of the world’s top custom builder.

But SEMA is more than just a showcase for the automotive aftermarket’s latest and greatest products. It’s a celebration of passion, design, and the relentless drive to push the boundaries of what’s possible in performance and style. Nowhere is that energy more alive than in the Battle of the Builders, where creativity takes center stage and every detail tells a story.

Now celebrating its 12th year, the SEMA Battle of the Builders has become the proving ground for elite craftsmanship. This isn’t just a competition—it’s a movement that fuels passion, precision, and progress in the custom car community.

From ground-up hot rods with flawless detailing to over-the-top off-road monsters and precision-built imports, every car in the Battle of the Builders 2025 Top 12 pushed design and engineering beyond convention.

Each finalist earned their spot after standing out from hundreds of entries that flooded the SEMA floor. The Top 40 were hand-picked by a panel of industry pros—but from there, only 12 builds advanced to the final stage, where the builders themselves took over judging duties.

Each category highlights a unique discipline within the custom scene, from vintage restoration and performance tuning to wild fabrication and new-age innovation.

Division Winner & Overall Champion

Troy Trepanier – 1936 Myers Fenderless Ford Roadster

When Troy Trepanier rolled this beast out in January 2025, the crowd went silent—then erupted. Winner of the GNRS AMBR Award, this isn’t just a 1936 Ford Roadster—it’s a radically reimagined open-wheel masterpiece. Every proportion was recalculated, every line honed, transforming a classic silhouette into a jaw-dropping, low-slung roadster that commands attention from any angle.

Rad Rides by Troy left nothing untouched: the body, chassis, suspension, and all machined components were fabricated in-house, with the same obsessive craftsmanship poured into the paint and interior. Under the hood roars a supercharged Ford 312ci Y-block, matched to a quick-change rear axle and full torsion bar suspension—a combination that’s as ferocious on the track as it is striking in the show field.

A SEMA Battle of the Builders Overall Winner (2017), Troy once again proves why his builds are the gold standard of creativity, execution, and sheer automotive artistry. This isn’t just a roadster—it’s Rad Rides at its boldest, most fearless, most unstoppable.

Division Winner 

Ron Jones – 1973 VW Thing

Ron Jones Garage has taken the humble 1973 VW Thing and transformed it into a rally-bred, Paris-Dakar–inspired powerhouse.
