Turning Heads In Tony’s Diamond T

The idea of “different” gets thrown around a lot in this industry. Different wheels. Different color. Different stance. But every once in a while, something shows up that forces you to recalibrate what that word actually means.

When we first saw Tony Leal’s 1948 Diamond T 404 at SEMA 2025, we knew it had to be featured. This build isn’t just different; it’s the kind of build that makes you stop mid-sentence, stare at it, and ask yourself how in the hell someone even thought to do this. Tony calls it the Slammed Hauler, but honestly we’re not even sure that scratches the surface of this insane build.

From Farm Truck to Monster

When it came to building a one-of-a-kind truck, Tony didn’t start with a pristine classic tucked away in some collection. Instead, he bought the truck out of Northern California from an older gentleman who had been restoring Diamond Ts. At the time, it was an old dairy delivery truck with a tank on the back. It had lived a working life, and the sins and scars of its past showed through at every angle. It wasn’t flashy, glamorous, or even worth saving to some. It was just old iron, but under all of the patina and broken parts, this truck had something that a new truck doesn’t: history. Most people who acquire a vintage Model T would have restored it or perhaps given it the once-over to make it drivable or even take it to parades on the weekends. But those who know Tony Leal know that he has a style unlike anyone else, and the Diamond T was about to get what we can only sum up as the “Tony treatment.”

The turning point for the build came in 2019 at Lone Star Throwdown, where Tony saw a 1948 International KB6 sitting on an air-ride chassis. It was at that very moment that something clicked, and Tony was off to the races. He didn’t want to restore the truck; he wanted something so over the top and so unexpected that it would steal the show wherever it rolled in.

Not blend in. Not compete for trophies or attention. Tony wanted a build that would turn heads, break necks, and create conversation no matter where he drove it. And when you look at this truck now, that mission feels accomplished.

A Chassis Worth the Wait

Underneath the original 1948 sheetmetal sits a 2022 Porterbuilt full-custom air bag chassis. And when we say custom, we mean designed from scratch! The frame alone took nearly two years to complete, which is longer than most folks will dedicate to an entire build. That equates to two years of engineering, refining, and obsessing over how this massive piece of history would sit, ride, and function.

With Air Lift 2600 bags up front, Firestone bags in the rear, Aldan shocks all around, and an Air Lift ALP4 management system feeding three 28-inch Flo tanks, this truck rides like a Sunday driver on the Anaheim roads. A Flaming River XL steering rack handles steering duties, and a custom fuel tank by Arizona High Test keeps the engine fed.

Everything about this build is intentional, thought out, and executed to a level that makes you truly appreciate the amount of effort that it took. From the shaved and tucked wiring harnesses to the hard line air management, the longer you look at this Diamond T, the more you find.

Industrial Patina, Preserved

Despite all of the attention and custom fabrication this Diamond T has, one of the smartest decisions during this build was what Tony didn’t want to change.

Instead of burying the truck in layers of glossy modern paint, Tony opted to preserve the original patina and locked it in with satin clear. The deep crimson red paint has varying degrees of fade, but instead of being a takeaway, these imperfections sum the truck up perfectly. It gives the build history, and the moment you see the truck, you wish it could talk. The names on the doors from its former life as a farm truck remain, and it only creates further conversation.

The grille and bumpers stayed stock, anchoring the truck to its roots. Summit Racing headlights bring modern visibility without distracting from the vintage face. Custom rear fenders make room for the modern chassis underneath. The rear tubs were custom fabricated, and the firewall was rebuilt. The list of body modifications is long enough that even Tony shrugs and says, “It’s too much to list.” ”.

But despite all of the custom work that Tony and his team put into this insane build, it still looks like a Diamond T. But instead of the rusted, dusted, and otherwise forgotten Diamond Ts that exist all over the country, this one came back from the grave. And it did so with a vengeance.

Compound Attitude

As far as we’re concerned, Tony could have finished up the exterior, interior, and suspension of the truck, and it would still break our necks. But those that know Tony know that he doesn’t do anything half-cocked, and this build is no exception. Popping the hood on this truck takes your breath away in more ways than one.

Underneath sits a 1998 5.9L Cummins inline six, balanced and blueprinted, built by Arizona High Test and R&M Enterprise. It’s been gone through and updated top to bottom, left to right, and the attention to detail continues in the engine bay. Keeping the Cummins breathing well is a compound Garrett turbo setup paired with a custom intercooler system that had to be carefully packaged to both function and look right.

Tony admits fitting the compounds under the hood and making everything look intentional was one of the biggest challenges, and rightfully so. We’re talking about putting a two turbo-fed inline six Cummins into a truck that was originally outfitted with a 205 cubic inch Hercules L-head engine. It wasn’t meant to have a Cummins in it, but Tony and his team didn’t care about that. He wanted something that was unique, which it truly is.

Backing the Cummins is a 2004 New Venture transmission, rebuilt and paired with a South Bend dual ceramic clutch. Braking is handled by an ABS Power Brake electric master cylinder. Every component was chosen to support the vision, not just the spec sheet.

Despite its age, the experience of riding in it is as good or better than some of the brand-new builds we’ve been in. The Cummins makes all the right noises, the manual transmission keeps you connected to the truck, and the air-ride means the truck rides incredibly well despite the large wheel and tire setup.

Interior That Changes the Conversation

If the outside makes you stare, the interior makes you stay.

Ceballos Customs took the cab and elevated it to 11. Saddle brown leather wraps bucket seats, and a custom dash panel makes the truck feel vintage, but in an updated and comfortable way. The richness of the leather against the preserved patina exterior creates a contrast that shouldn’t work but absolutely does. It doesn’t feel like a restored antique. It feels like a handcrafted piece of rolling art that just happens to be capable of lighting the compounds and shaking the ground.

Time, Money & Reality

Five years of time, enough money to fund a startup business, and if you ask Tony about budgeting, he’ll laugh and tell you they tripled what they originally thought.

Custom fabrication and interior work quickly climbed; the frame alone demanded patience, and like any good build, there were plenty of major hiccups and setbacks along the way. From air line routing to rear cover details that evolved during the process, there were plenty of times that Tony could have cut corners or thrown in the towel, but nothing derailed the vision that he had for this build.

If you ask him, Tony will tell you he always knew the truck would get finished, despite all of the potential pitfalls that stand in the way. Life happens, and builds get pushed to the back burner, but eventually you circle back to where you started. Progress starts again, excitement returns, and it’s back to the races.

When we asked Tony what he was most proud of, his answer was simple—that it’s done. And while we think it’s easy to write this off as a half-baked answer, you begin to understand that it’s not a shortcut after talking with Tony. It’s the celebration of 5 years of hard work, dollars invested, and collaboration with some of the most incredible builders and fabricators in the industry.

Bigger, Badder, Bolder

Tony will tell you if you’re thinking about building something like this, go buy a house instead. In the same breath, though, he’ll also tell you if you put your mind to it and enough money behind it, you can build pretty much anything.

When it comes to the future of this build, the truck is about 99 percent finished. The boost still needs a little bit of dialing in. After that, it’s ready to stretch its legs at more shows and finally get the attention it deserves.

When people see it in person, they don’t always believe it’s real. They think it looks like a Hot Wheels truck—something too exaggerated to exist outside of a toy aisle. But it’s real, it’s detailed, and if you’re lucky enough to get a ride in it, it’s a surreal experience unlike anything else.

At one point, this Diamond T was an old farm truck parked in the weeds, probably thinking its life was over. Now it sits slammed over a custom Porterbuilt chassis, breathing through compound turbos and six-inch stacks, and wearing its history proudly under satin clear.

If this truck could tell its story, Tony says it would say it died and came back bigger, badder, and bolder than ever. And honestly, we think that’s pretty accurate.
