The October 2023 digital issue of Diesel World captures the sights, sounds, and excitement of the 2023 Ultimate Callout Challenge, including exclusive coverage of the drag races, dyno competitions, sled pulls, and more! We also feature a beefed-up ’70 GMC K15 as it gets new life on the track, a ’68 International Loadstar that goes totally against the grain, and Aaron Brose’s dragstrip destroyer: a 900hp shortbed. But that’s not all! We check out David Keyser’s daily-driven OBS FORD F-250, and our Truck of the Month—Chris Voorheis’ ground pounder that’s ready to race! Also check out our Diesel World November 2023 Digital issue.

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
