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 history. The Cummins*-powered truck enthusiast has since produced 1,200 videos that have amassed 82 million views and 300,000 followers to his channel. The Kentucky-based mechanic has also built an eye-popping collection 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 beastly.
Climbing In
Alberalla purchased his first diesel truck when he was just 18, a 2005 RAM* 2500. Alberalla took a wrench to it and it started to evolve. But when he took it to a track and broke the transmission, he took things to a new level. He turned it into a beast that straddles the line between outrages street truck and 1,500-hp race truck. The truck features a Freedom Racing Engines powerplant, upgraded turbo and suspension and safety equipment for going fast. But the build didn’t just alter the truck; the truck altered him, drawing Alberalla further down the diesel-enthusiast path he’s still on today.
From new truck owners to professional mechanics, Alberalla’s authenticity and hands-on approach have made him a trusted figure in the diesel truck world. Whether he’s documenting his 3,000-hp Cummins build (more on that later) or a tutorial on how to change your oil, Alberalla’s videos are educational and entertaining.
“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 expertise in diesel engines, particularly Cummins-powered RAMs, provides him with a solid niche in a crowded field of content creators. While many YouTubers focus on exotic vehicles, Alberalla has kept his content grounded in diesel trucks. His channel offers mechanical insights, product reviews and down-to-earth advice, making them required viewing for anyone looking to maintain, upgrade or push the limits of their diesel truck.
From his first-gen street-race truck to his 3,000-hp Cummins-powered monster, Alberalla’s personal truck collection puts his deep appreciation for Cummins power on display. When Alberalla endorses a part or a tool, his viewers know it’s been thoroughly tested in real-world conditions by someone who lives in the diesel world.

The Why
Alberalla has continuously showcased his reputation for detail and quality through his partnerships with premium brands. His collaboration with Banks Power is one standout example. When Alberalla installed their Ram-Air differential cover on his RAM, he didn’t just say it was an excellent product. He took it further and dove into its design and engineering, analyzing how their scoops directed airflow to cool the fins and why this was a smarter alternative than the deeper fins used by competitors. This commitment to explaining his reviews and his emphasis on innovation have helped Alberalla build trust with his fans.
3,000 Horsepower Gitty-Up
Alberalla typically focuses his camera on practical knowhow, but he’s just as comfortable in the world of high-performance diesel builds. Out of his many projects, the Cummins-powered truck that got him into the exclusive 3,000-hp club deserves honorable mention. The build is a testament to his technical expertise and the enjoyment he extracts from pushing diesel engines to the outer limits. Built for quarter-mile runs and dyno events, the truck typifies diesel power.
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 is flourishing and he’s still having a blast documenting his diesel adventures. From jaw-dropping 3,000-horsepower feats to everyday maintenance tips, Alberalla’s work is helping the rest of us grab a wrench and start building – and maybe join a community of diesel enthusiasts in the process.
