The November 2025 issue of Diesel World is stacked with legendary builds, groundbreaking tech, and can’t-miss event coverage. On the cover, Garret’s 2,000-hp Firepunk-built Ram nicknamed OG Niss cements its place in diesel history as one of the most powerful trucks ever featured. We also take a deep dive into the Audi R10, the diesel-powered racecar that changed the game on and off the track.
Inside, you’ll find a wide range of diesel features, from Mark’s beastly single-turbo 6.4L Power Stroke to Dustin’s community-focused
LBZ Duramax build. We showcase a slammed, bagged, and bodied 2025 Silverado 3500, plus shine a light on Southern Diesel Supply in our Shop Spotlight. Our Influencer Insider catches up with Blake Fitzgerald, who’s been making big waves in the diesel scene.
On the event side, we bring you full coverage of the Ultimate Callout Challenge 2025 new classes, wild builds, and the same adrenaline-packed action. Dan’s Diesel Performance Open House also makes the pages with a spring weekend full of horsepower.
Tech fans won’t be left out either: from essential routine maintenance with AMSOIL and a hands-on junkyard turbo rebuild with Riffraff Diesel to updates on our Stock to Not SEMA project, there’s plenty to learn and apply. Add in the latest hot products, event listings, and columns, and this issue is a must-have for anyone living the diesel lifestyle.

What I really enjoy about Diesel World Magazine is the in-depth truck features and the real-world project builds. The photography is always sharp, and the tech articles give solid info without feeling overcomplicated. It’s just a great read for anyone who’s into diesel trucks.

Great Source for Real Diesel Builds I’ve been flipping through Diesel World for a while now, and what keeps me hooked are the detailed truck build features. It’s not just surface-level photos—you get the full story behind each project, from the engine mods to the suspension setups. It’s cool seeing what real truck owners across the country are doing with their rigs. Makes me want to spend more time in the garage
