Diesel Motorsports Turned ALL THE WAY UP!

There are diesel events, and then there’s Ultimate Callout Challenge. If you’ve been around the diesel world for more than five minutes, you already know UCC isn’t some casual weekend where a few fast trucks show up, make a couple of clean passes, and everyone goes home early. UCC is loud, chaotic, expensive, stressful, and usually at least a little bit unhinged. In other words, it’s exactly what makes diesel motorsports worth watching.

For 2026, UCC returned to Lucas Oil Indianapolis Raceway Park for its 10th anniversary, and the whole weekend felt like it showed up with something to prove. Indy became the center of the diesel universe from June 5 through June 7 between Ultimate Callout Challenge, Firepunk Outlaw Diesel Revenge, and the $70,000-to-win Seventy2Fast race. There were thousands of spectators, hundreds of racers, full vendor rows, packed staging lanes, and enough horsepower on the property to make you question everyone’s financial responsibility in the best way possible.

The actual UCC competition brought the kind of drama you’d expect from an event built around drag racing, dyno pulls, and sled pulling. First-time competitor Myer Stump came out swinging in his common-rail Cummins-powered second-gen, laying down a 5.14-second eighth-mile pass before coming back with a 4.90 at 155 mph. That alone would’ve been enough to get people talking, but Myer was just getting started.

On the dyno, he put down a smooth 3,620 horsepower. Then, after a complete frame swap in the pits before the sled pull, he went out and dragged the sled 355 feet to lock up the overall UCC win.

Myer wasn’t the only one making noise, though. Justin Zeigler brought one of the most storied trucks in UCC history back into the spotlight and put down a record-setting 4.57-second pass at 171 mph in the eighth-mile, good enough for first place points on the drag strip. Tim Moore and the Poor Boys Diesel Performance crew also made sure nobody left Indy without knowing their name. Their Mega Cab went 5.01 on the drag strip on a leaf spring suspension, then strapped to the dyno and made a record-setting 3,825 horsepower on a cast-iron block with a big single turbo, which is pretty insane if you ask us.

Ken Bruner, the 2024 UCC champ, stayed right in the fight as well, finishing second place overall with a 5.27-second drag pass, 3,098 horsepower on the dyno, and a 319-foot sled pull. It was the kind of performance that reminded everyone that surviving all three portions of UCC is its own kind of skill. One big number is cool. Three solid days is how you stay near the top.

And then there was Seventy2Fast, which might’ve been the most talked-about piece of the whole weekend. Lavon Miller and the Firepunk crew did an incredible job building the hype, and when the time came, the class absolutely delivered. More than 100 trucks showed up for a heads-up, instant-green, no-time, single-elimination dogfight built around a spec 72 mm VS Racing turbo, diesel fuel only, no nitrous, a 6,000-pound minimum, factory ECMs, air-to-air intercoolers, and foot-brake staging. The idea was simple: take away some of the usual advantages, put real money on the line, and make the drivers race. News flash: It worked.

The Seventy2Fast trucks pitted down the return road, which meant every round felt like a parade past the grandstands before the next batch of trucks headed to the staging lanes. The windshield banners let everyone know what was coming, and by the time eliminations started rolling, the stands and barriers were stacked with people waiting to see who’d survive the next pair. With no timeslips and no amber bulbs, every pass had that grudge-race tension baked into it. Two trucks rolled up, the tree dropped, and one driver moved on.

Matthew Parker eventually took the win over Stephen Grundke in the final, earning the $70,000 payday and sending the biggest diesel drag racing check back to Texas. That win felt right, too. Parker had clearly put in the work before Indy, building, testing, changing, fixing, and preparing his truck for exactly this kind of race. In a class designed to reward preparation, driving, and making the most of the rulebook, the guy who did the work went home with the money.

Outlaw Diesel Revenge added another layer to the weekend. Presented by Firepunk Diesel, the ODSS race drew more than 280 tech cards and remained the biggest ODSS race on the calendar. For 2026, it also served as the first crossover points event where racers could earn points separately in both ODSS and NHRDA, which only added to the weight of the weekend.

And of course, Michael Cordova reminded everyone why he’s the fastest man in diesel, sending the S&S Diesel Motorsport dragster into the 3-second zone more than once and taking the Top Diesel win. Phillip Franklin fought through mechanical issues and drove Truck Source Diesel’s third-gen Dodge to the Pro Truck win. Ryan Reiser put a 6.7L Power Stroke at the front in the 5.90 Index. Rudy’s Performance Parts debuted its 6.4L-powered Mustang and took the Super Diesel win. Brent Allred won the 6.70 Index, Matt Maier drove his 7.3L OBS Ford to the 7.70 Index win, and Nick Morris showed why he’s one of the most respected bracket racers in the diesel world by taking the ET Bracket.

That’s what made UCC 2026 feel so big. It wasn’t just one headline. It was all of them stacked together. Record drag passes, 3,800-plus horsepower dyno runs, sled pull drama, a new UCC champion, the biggest ODSS race of the year, and a Seventy2Fast race that proved diesel racers are still hungry for simple, real, high-stakes drag racing.

Ten years in, Ultimate Callout Challenge didn’t just celebrate an anniversary in a simple way. Instead, it reminded everyone why it’s still the biggest weekend in diesel.
