Steve Darnell Wiki, Bio, Age, Net Worth, Wife, Kids & Career Facts.

Before you dive into the horsepower, raw metalwork, and post-apocalyptic rat rods, meet the man who built it all: Steve Darnell—American custom car builder, master fabricator, and television personality best known for leading the Discovery Channel’s Vegas Rat Rods. His story isn’t just about turning wrenches; it’s about crafting a legacy from the ground up, often with parts scavenged from places most people wouldn’t give a second glance. From childhood days in Montana and Nevada, learning the trades of ranching and steel work, to transforming rusted shells into roaring icons on international television, Steve’s journey is a blueprint of grit, creativity, and relentless drive. This biography takes you inside his life—covering his background, career, passions, notable builds, and other defining aspects—offering a clear picture of how he became one of the most recognized names in the custom car world.

Early Life

Steve Darnell was born on December 1, 1960, in Billings, Montana, and grew up splitting his time between Montana and Nevada. At age six, he moved from Las Vegas to Billings with his mother, but summers were spent back in Las Vegas working alongside his father, Chuck Darnell, at Economy Steel. By the time most kids were still learning to ride bikes, Steve was running forklifts and other yard equipment, absorbing the welding and fabrication basics that would later become the backbone of his career.

Winters in Montana brought a different kind of education. On his uncle’s cattle ranch in the eastern part of the state, Steve was driving trucks and tractors by about seven years old—learning to work a manual transmission while hauling feed for cattle. The rugged, hands-on ranch work blended with the steel yard grind to give him an early taste of self-reliance.

Steve also grew up with an older sister, two and a half years his senior, who often pulled him back from going “too far” with his wild ideas. That early push-and-pull dynamic became a quiet but important influence, helping him balance creativity with level-headed decision-making—something that would prove valuable when she later took on the role of running the business side of Welder Up.

Money was always tight, and his knack for making do started young. His mother, a waitress at the time, would bring home mismatched model car kits from garage sales. Missing parts didn’t slow him down—he improvised, building custom creations in his bedroom before he was even ten. At nine, he entered a Pinewood Derby with a home-built car sporting fat rear tires, skinny front gasser wheels, and a blown big-block engine detail. It was too radical to race properly—the headers scraped the track—but it won “Best Looking Car” and earned him his first taste of attention for doing things his own way.

As a teenager in Billings, Steve hustled to get his first real cars, selling his bicycle to buy a 1973 Datsun that he kept alive with junkyard parts. Later, he drove a 1970 Chevrolet Blazer to high school. The back-and-forth rhythm of ranch chores, steel yard labor, and the car-culture stories he heard from his parents—who once cruised Fremont Street in Las Vegas in the ’60s—cemented his obsession with machines and his instinct for building them from the ground up.

Career and Rise to Fame

Steve’s professional journey began with 13 years working alongside his father, Chuck Darnell, at Economy Steel in Las Vegas. The experience honed his welding and fabrication skills and instilled the work ethic that would define his career. Eventually, he launched his own fabrication business, Welder Up, initially taking on general fabrication and production work. In 2006, when the market downturn slowed business, Steve took his father’s advice to pursue a passion project—building custom hot rods. This decision shifted the focus of Welder Up and set the stage for national recognition.

Steve’s passion for cars was deeply rooted in his upbringing. From driving trucks on his uncle’s ranch before he was ten to scavenging junkyards on his bicycle for spare parts, he learned early how to improvise repairs and create from what was available. His creativity was nurtured by building mismatched model kits his mother found at garage sales, and it evolved into reviving old farm vehicles and customizing his first personal cars as a teenager.

One of his most significant builds is The Destroyer, a 1928 Dodge truck that once belonged to his grandfather, a decorated World War II veteran. The project was both a tribute and a technical challenge, resulting in a 693‑rwhp Cummins turbodiesel-powered rat rod capable of running the quarter-mile in 11.69 seconds at 118 mph. Completed in just over three months with nearly 1,000 hours of labor, it became the mascot of Welder Up and a centerpiece of his Las Vegas showroom. Another milestone came in high school when he bought and modified a 1957 Chevy 210—eventually turning it into one of his most recognized street machines with a turbocharged, fuel-injected engine producing around 740 horsepower.

His distinctive, imaginative builds—often crafted from salvaged parts—caught attention and led to the Discovery Channel reality series Vegas Rat Rods, which aired from 2014 to 2018 over four seasons. The show spotlighted Steve and his eclectic crew as they transformed abandoned, rusted vehicles into bespoke rat rods, often with “Mad Max”-inspired designs that blended performance with artistry. The series propelled Welder Up into the national spotlight and brought rat-rod culture to mainstream audiences, earning features in Hot Rod Magazine, Diesel World, and Mopar Magazine.

Steve’s creative reach expanded in 2014 when he produced and designed vehicles and the set for Five Finger Death Punch’s music video for “House of the Rising Sun,” adding a gritty, post-apocalyptic aesthetic that matched the band’s style. Beyond television and music, he has built a strong online presence through YouTube, social media, and his welding course at welder101.com, sharing his hands-on expertise with aspiring builders worldwide.

Notable Builds and Inspirations

• The Destroyer (1928 Dodge): Built in just 3½ months with ~1,000 hours of work, this Cummins turbodiesel-powered rat rod produces 693 rwhp and runs the quarter-mile in 11.69 seconds.
