In the world of custom car builds, few names command the respect and awe that Ringbrothers do. Known for their meticulous craftsmanship and bold design philosophy, the Wisconsin-based duo of Jim and Mike Ring have once again stunned the automotive world with their latest creation: Kingpin. Unveiled at the 2025 SEMA Show in Las Vegas, this 1969 Ford Mustang Mach 1 restomod is not just a tribute to American muscle—it’s a full-blown reinvention.
🔧 A Build Born from Passion and Precision
The Kingpin project took over 5,000 hours to complete, and every minute is evident in the final product. Ringbrothers didn’t just restore a classic—they reengineered it. The original Mustang shell was stripped down and rebuilt with carbon fiber and billet aluminum components, giving it a lightweight yet incredibly strong foundation.
The body retains the iconic lines of the ’69 Mach 1 but with subtle enhancements that modernize its silhouette. Custom fender flares, a lowered stance, and aggressive front and rear fascias give Kingpin a menacing presence without compromising its vintage soul.
⚙️ Powering the Beast: Over 800 Horses Unleashed
Under the hood lies a Ford Coyote V8 engine, supercharged to produce over 800 horsepower. This isn’t just brute force—it’s precision-tuned performance. The engine is mated to a six-speed manual transmission, giving drivers full control over every ounce of power.
Ringbrothers have also equipped Kingpin with a custom exhaust system, ensuring that its roar matches its muscle. The sound is pure Americana—deep, throaty, and unapologetically loud.
🧠 Engineering Excellence
Kingpin rides on a custom-built chassis designed to handle the immense power and deliver razor-sharp handling. The suspension setup includes adjustable coilovers, independent rear suspension, and performance sway bars, making it as capable on the track as it is on the street.
Braking is handled by high-performance disc brakes at all four corners, ensuring that this beast can stop as quickly as it accelerates. The wheels are forged alloys wrapped in Michelin performance tires, providing grip and style in equal measure.
🎨 Interior: Where Retro Meets Luxury
Step inside Kingpin and you’re greeted by a cabin that blends classic Mustang cues with modern luxury. The dashboard features custom gauges, leather-wrapped surfaces, and billet aluminum accents. The seats are hand-stitched leather, offering both comfort and support.
Ringbrothers have also integrated modern tech, including a touchscreen infotainment system, Bluetooth connectivity, and premium audio. It’s a space that respects the past while embracing the future.
🏆 SEMA 2025: A Showstopper
Kingpin was one of the headline builds at the 2025 SEMA Show, drawing crowds and praise from enthusiasts and industry insiders alike. Positioned at Ringbrothers’ booth, it stood as a testament to what’s possible when craftsmanship, creativity, and engineering collide.
According to Ringbrothers, Kingpin “pushes the limits of performance and aesthetics of one of America’s most iconic muscle cars”. It’s not just a build—it’s a benchmark.
🎯 Who Is Kingpin For?
While Kingpin is a one-off showpiece, it represents the pinnacle of what restomod culture can achieve. It’s for:
- Collectors who appreciate bespoke craftsmanship
- Performance enthusiasts who crave modern power in a classic shell
- Design aficionados who admire the fusion of retro and contemporary aesthetics
- Ringbrothers fans who follow their builds like art installations
Kingpin isn’t just a car—it’s a rolling sculpture, a mechanical symphony, and a love letter to American muscle.
🏁 Final Thoughts
Ringbrothers’ Kingpin is more than a 1969 Mustang Mach 1—it’s a redefinition of what a restomod can be. With over 800 horsepower, custom everything, and show-stopping style, it’s a build that honors the past while blazing a trail into the future.
In a world of cookie-cutter customs, Kingpin stands alone—bold, beautiful, and utterly unforgettable.
