Diesel World Magazine - November 2025

In this issue

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.
