When you think of endurance racing, images of high-revving gasoline screamers often flood the mind. Tons of machines built for power, speed, and aggression. But in 2006, Audi did something no one expected. They didn’t just challenge the gasoline establishment; they overthrew it—with a diesel. Enter the Audi R10 TDI, the first diesel-powered racecar to win the 24 Hours of Le Mans and arguably the most disruptive force to ever hit endurance racing. Audi’s decision to field a diesel prototype wasn’t a gimmick. It was a calculated risk, backed by engineering confidence and a deep understanding of both competition and innovation. The R10 TDI was built to replace the R8, which was an already legendary gas-powered car that won Le Mans five times, just with a radical twist: a 5.5-liter…

In today’s world, the options for 7.3L Powerstroke turbo replacement are seemingly endless. Aftermarket replacements and upgrades are everywhere. With all these options, we rarely hear about rebuilding our own turbo. It’s a surprisingly simple process and often comes with upgrades too. If you’re not looking to add gobs of extra horsepower, it’s hands down the most inexpensive way to replace your failed turbo, if you’re willing to get your hands dirty. Here we’ll be rebuilding a junkyard turbo with parts from Riffraff Diesel. We picked a junk yard turbo because we wanted to see how far gone a turbo could be, and still be returned to operational status. After about 2 hours of work (most of which was spent cleaning rust and other deposits), we were able to take…

I’m going to be honest with you; the idea of writing this feature still feels like a pipe dream. I’ve been really blessed in my life and had a LOT of really cool experiences, but building something worthy of being published in a magazine is an honor that I didn’t know I would get to experience. And I gotta say, it’s pretty freaking cool. What you’re looking at here is my truck, a 2007 Silverado 2500HD. Now let’s get this out of the way right away—this truck is not a museum piece. Heck, between you and me, I would hardly even call it a show truck. This one has its fair share of battle scars. The frame could use a sandblast and coating, the bedsides are starting to show some…

Last month, you saw us having some transmission issues with our editorial truck VERY far form home.. Well, we’ve gotten the transmission back in the truck with some swift shipping of a fresh converter from RevMax and a refresh from our Manual Valve body from Muldoon’s to make sure it’s ready for some more abuse. Our buddies with Fesler Auto and my friend Evan housed the truck in Indianapolis while everything fell into place, so i flew out to get the truck back together and running to make my way home back to Oklahoma the next day. We’re bringing this build to SEMA 2025 with Liberty Forged Wheels, so we have to get this truck to a show ready state. First things first, we grabbed a new (to me) frame…

While the smoke has settled and the dust has cleared the air at the iconic Lucas Oil Raceway, it’s hard to believe that another incredible Ultimate Callout Challenge has come to pass. While we’re sad it’s over, we’re happy that it happened, and in case you missed it, we’ve got you covered. At the 2025 Ultimate Callout Challenge (UCC), attendees didn’t just witness the biggest event in its history—they became part of it. From the ultra-competitive ODSS/ODR drag classes and the invite-only Seventy2 Fast bracket to the countless booths in the alleys of DPI, UCC felt less like a show and more like a diesel-fueled family reunion. The team behind Ultimate Callout Challenge has been building this momentum for years. What started as a niche event for high-performance diesel fans…

Here at Diesel World, we’ve seen A LOT of builds, and it’s pretty rare that we find one that truly stops us in our tracks. But this one might just take the metaphorical cake of what it means to build a truly unique truck. Meet Garret Niss’ 2006 Dodge Ram 2500. We’d call it incredible, but we’re not sure that covers it. Now, before you assume this is just another overbuilt showpiece destined for a trailer and a life spent in climate-controlled garages, let us clear that up: this truck has roots—real roots. Garret bought this thing at 16 years old off Craigslist, back when Moto Metals and a 6-inch lift were all a high school kid needed to feel like king of the parking lot. The truck came up…

Bigger is better”—it’s a saying we’ve all heard, but for Jake McKiddie, it’s a way of life. As the owner and master fabricator behind Phat Phabz, Jake has carved out a reputation for pushing the limits of custom automotive design. His shop’s builds aren’t for the faint of heart, and his latest project proves once again that when it comes to custom trucks, he’s operating on an entirely different level. Living in Choctaw, Oklahoma—where dual-wheeled trucks are as common as thunderstorms—Jake knew that if he was going to tackle another custom dually, it had to truly stand out. He wasn’t aiming to just build a showpiece; he needed a truck that could pull a heavy gooseneck during the week and shine under the lights at any major truck show on…

In the world of diesel trucks, standing out takes more than just big wheels and lots of horsepower. It takes vision, dedication, and a whole lot of late nights spent chasing perfection. Blake Fitzgerald embodies all of that. As the founder of Fitzgerald Performance, Blake isn’t just building custom Cummins trucks; he’s pioneering a culture that stretches far beyond the walls of his Jamestown, Tennessee shop. Blake didn’t fall into this by accident. From the first time he picked up a wrench, it was clear he wasn’t going to settle for stock. Fitzgerald Performance has become synonymous with high-performance diesel trucks, specifically the Cummins builds that break necks both in person and online. If you’ve spent more than three minutes on diesel Instagram or TikTok, chances are good you’ve seen…

Routine diesel maintenance can be equal parts satisfying and aggravating. An oil change may seem like a simple task, but the runaround—from miscommunicating with counter staff to paying dealer prices—can turn routine into a headache. And besides all that, it’s hard to know if the product you’re using is actually doing a good job protecting your engine. It doesn’t need to be that way, though, and AMSOIL is here to help. For decades, AMSOIL has led the synthetic-lube revolution. In 1972, it became the first company to earn an API certification for synthetic motor oil, solidifying its reputation as “The First in Synthetics.” Today, AMSOIL offers a comprehensive line of diesel-specific formulations engineered for heavy-duty use and long-drain intervals. Here are the key reasons diesel owners are reaching for AMSOIL…

 When I first started Big Time Kustomz, I instantly became obsessed with horsepower and the Power Stroke motors,” says Mark Vanadia. “We spent years trying to make my pride-and-joy red truck that was lifted 10 inches and on 24-inch wheels and 38-inch tires go fast with more power. I learned after capping 1,000 hp that the task takes a toll on a truck that big. I always spent more time fixing it than enjoying it. I found a rolling chassis that had a roll bar in it and instantly fell in love with the idea of building a dedicated, fast, power-driven truck. I believe the words from my wife were, ‘Buy the truck so you can stop complaining about breaking your red truck.’ So I did.” “Instantly, I reached out…

As I parked and walked up the narrow roadway, the sound of a diesel truck making a hit on the dyno filled the air. It was a crisp Saturday morning, and I had found myself at the one and only Dan’s Diesel Performance location for its Spring Open House Event. As I rounded the corner into the lot, the first thing that stood out to me was the variety of both trucks and companies that were present at the event. HSP Diesel, Dirty Hooker Diesel, and more all had booths at the event, showcasing new products, brand-new builds, and otherwise just hanging out to show that they’re not just a brand; they’re truly big players within the industry. The dyno was the highlight of the day during the morning hours.…

Let’s face it, there are a lot of places to get your diesel parts from these days. After all, the Internet has made the rise of e-commerce commonplace by today’s standards. With that being said, there are still stories of brands that are truly chasing a dream, trying to better the industry, and overall just making the right moves at the right times. Southern Diesel Supply is the subject of one of those stories. This is Ben Hinz’s story, a tale of grit, grind, and good old-fashioned American hustle that transformed a backyard parts hustle into one of the most trusted diesel parts suppliers in the game. When Ben first dipped his boots into the diesel world, he wasn’t setting out to build an empire. Like a lot of us,…

It’s a funny thing, really, the way the world works. When you say it out loud, it sounds really simple: The path to get to this very moment was not one big decision, but thousands upon thousands of tiny decisions that ultimately shaped the path of your journey. It’s a crazy journey, and one that even the best of the best still don’t quite have figured out. Despite how far we go, we somehow end up coming back for more. To some, it’s tearing into a project knowing you’re not sure what you’re doing. To others, it’s coming back for another year at Ultimate Callout Challenge after you said last year really “was your last year” (Mr. Patterson, I’m looking at you). And for others, it’s getting pulled into helping…
