As we get geared up to head out to Indiana for the Ultimate Callout Challenge , we figured we’d show you our lineup and a few of our goals for the races this year!! We’ve got both our newest build, the 800hp 3rd gen, and our oldest build, the wannabe show and shine Big Blue, heading out tonight for this weekends festivities!! We hope to see some of you guys there!!

Though it may not be as much a rocket ship as the rest, we were very excited to have our 3rd Gen cross into the 7’s for the first time down at Edgewater Sports Park Truckfest. First was a 7.96 followed by the fastest of a 7.88. Hopefully with a lockup switch for 2nd gear, it’ll be more competitive in 7.70 at Ultimate Callout Challenge this weekend! We’ll see you guys out there.

We finally finished setting up our race trailer and it’s officially ready for the season. What started as a 6x10 trailer is now a fully equipped mobile workshop that will be with us at every event. Even better, if you’re at an event we’re at and need a quick repair or a tool, we’re happy to help get you back in action. Want to know what we’ve got? We just put a full tour up on YouTube!! Link in bio and comments below!!

I dunno, what do you guys think? Does this truck need a heater core?

Those spicy Shift On The Fly tunes give folks a few more options and a little more horsepower than some of their trucks can handle. This one came in for some upgrades and after giving fair warning that anything over tune 1 would roast it, here it is back once again. 3 days into driving it and the clutches have exited the chat… Here’s how we’re making sure it won’t happen again!

The diesel industry has become a bit notorious for its lack of quality control, and after this incident, we’re wondering if even the biggest names in the industry are starting to suffer from this dilemma!! Have you guys had a similar experience to this? Who do you think should pay for mistakes like this? Let us know in the comments below…

They filled the tank with everything but diesel, changed the oil with the engine running, and shot so much nitrous into the intake—but it hasn't quit yet. https://trib.al/tMXBFRW

The 2,000HP 6.4 build just took a massive step forward!! 🔥 Huge thanks to Kill Devil Diesel for building this insane race engine for our project. This thing is going to completely change the direction of our race truck, and we’re just getting started!! Go check out the unboxing of this $30,000 beast and learn more about what we’re doing to hit that 2,000hp goal!!
