Greg Alberalla: Built, Not Bought

Greg Alberalla, or “Greg A” to his fans, made a bold career shift in 2016 when he transitioned from running a performance parts retail store to becoming a full-time content creator – and the rest, as they say, is diesel history. The Cummins-powered truck enthusiast has since produced more than 1,200 videos that have amassed over 80 million views and a YouTube following that now sits at 300,000-plus subscribers. The Kentucky-based mechanic has also built an eye-popping fleet of diesel trucks. From a tube-chassis quarter-mile race truck to a Gen 5 dually tow rig, Alberalla builds trucks that are both beautiful and undeniably beastly.

Climbing In

Alberalla purchased his first diesel truck at just 18 years old — a 2005 RAM 2500 that would eventually become the most talked-about diesel drag truck on the planet. Like most first builds, it started simply. Greg took a wrench to it, upgraded parts as he learned, and let the truck evolve naturally. That evolution took a sharp turn after a trip to the track ended with a broken transmission. Instead of dialing things back, Alberalla doubled down.

What began as a street-driven daily slowly transformed into a truck that blurred the line between outrageous street machine and full-blown race truck. Out went mild mods. In came serious hardware: a Freedom Racing Engines-built Cummins, upgraded turbo systems, reinforced suspension and full safety equipment for going very fast. The build didn’t just change the truck, it reshaped Greg’s entire path in the diesel world.

From new truck owners to seasoned mechanics, Alberalla’s authenticity and hands-on approach have made him a trusted figure in the diesel community. Whether he’s documenting a four-digit horsepower build or walking viewers through a simple oil change, the content is always educational, candid and real.

“From a young age, I have always been into turning wrenches in the garage and diesel motorsports building trucks,” said Alberalla. “I started a YouTube channel as a hobby that has grown into a fulltime job making videos of building trucks and traveling to races and events with our builds.”

Garage Super Star

Alberalla’s deep knowledge of diesel engines — particularly Cummins-powered RAMs — has carved out a solid niche in a crowded content space. While many creators chase supercars and exotics, Alberalla has stayed grounded in diesel trucks. His channel delivers mechanical insight, honest product reviews and practical advice that resonates with people who actually wrench on their own rigs.

From his early street-race setups to what would eventually become a 3,337-horsepower Cummins monster, Alberalla’s personal truck lineup puts decades of diesel evolution on display. When he endorses a part or a tool, his audience knows it’s been tested the hard way — under load, on the dyno and at the track.

The Why

Alberalla has built his reputation through attention to detail and a commitment to quality, a mindset that carries through his brand partnerships. One standout collaboration is with Banks Power. When he installed their Ram-Air differential cover, he didn’t just praise it — he explained why it worked. He walked viewers through the airflow design, cooling strategy and engineering decisions that made it smarter than competing options. That willingness to break down the “why” has been key in building trust with his audience.

Street Truck to Record Breaker: The 3,337-HP Cummins

The truck that now holds the diesel chassis dyno horsepower record didn’t start as a record-holder, it started as a daily driver. Over nearly two decades of ownership, Alberalla’s 2005 Ram has gone through multiple engines, transmissions and full rebuilds, evolving as diesel performance technology advanced.

In 2015, the truck was already pushing boundaries by making 980 horsepower, a nearly unthinkable number for a street-oriented diesel at the time. As turbos grew larger, fueling systems improved and engine architecture advanced, Alberalla continued raising the bar. What was once a “wild” street truck transitioned into a purpose-built race and dyno platform.

That long-term development culminated in 2025, when the truck stunned the diesel world by laying down 3,337 horsepower on an industry-standard SuperFlow dyno — officially setting the highest recorded diesel pickup dyno number to date, edging the previous record by a single point. Importantly, it wasn’t a one-hit wonder. The truck has repeated 3,000+ hp dyno pulls multiple times, cementing its legitimacy and proving the combination’s durability and consistency.

More than just a number, the record is the result of years of iteration, setbacks and refinement, mirroring Alberalla’s own growth as a builder. The truck stands today as both a rolling history lesson in modern diesel performance and a benchmark for what’s currently possible.

3,000 Horsepower Gitty-Up

While Alberalla typically focuses his camera on practical know-how, he’s just as comfortable in the rarified air of extreme-performance diesel builds. The record-setting Cummins isn’t about shock value; it’s a case study on how far diesel engineering has come. Built for dyno events and quarter-mile punishment, the truck exemplifies what happens when passion, patience and technical expertise converge.

Despite this achievement, Alberalla never loses sight of practicality. His ability to juggle over-the-top horsepower builds with everyday truck projects highlights his versatility as a creator. He teaches fans that, while raw power is thrilling, reliability and functionality are key.

Driving into the Future

Alberalla shows no signs of slowing down. His YouTube channel continues to grow, his builds keep pushing limits and his enthusiasm for the diesel community remains contagious. From record-breaking horsepower feats to everyday maintenance tips, Alberalla’s work is proof that the best builds aren’t rushed — they’re earned one wrench turn at a time.
