Corey Heim Stuns NASCAR By Securing Double OT at Darlington

If there is one unwritten rule at Darlington Raceway, it is that “The Lady in Black” will break your heart just when you think you have everything figured out.

On a chaotic Friday night under the South Carolina lights, Ross Chastain learned that lesson the hard way. Cup Series veteran, leading the pack, white flag in sight, it was his race to lose. And then came Corey Heim.

In a finish that will be replayed on sports highlight reels for the rest of the year, Heim snatched the Buckle Up South Carolina 200 victory right out of Chastain’s hands during a wild double-overtime scramble.

It was a masterclass in late-race strategy, raw driving talent, and the kind of brazen audacity that makes NASCAR Craftsman Truck Series racing absolute appointment television.

1. The Overtime Drama at Darlington Raceway

Let us set the scene. The race had devolved into a demolition derby of late cautions, setting up a double-overtime shootout. Chastain, behind the wheel of the Trackhouse Racing entry, had led 35 laps and looked to be cruising toward a hard-fought victory. Kaden Honeycutt, who put on a clinic earlier in the evening by leading a race-high 59 laps, was also in the mix, fighting for scraps in the top five. But down in the pits, TRICON Garage made a call that changed the trajectory of the entire weekend. They bolted a set of fresher, scuffed tires onto the No. 5 Toyota of Corey Heim. When the green flag waved for the final restart, Heim was buried back in 15th place. To the average spectator, he was completely out of the equation. But with the grip of those fresher tires, Heim sliced through the field like a hot knife through butter. He climbed to ninth. Then he broke into the top five. By the time the field thundered toward Turn 3 on the final lap, Heim was right in Chastain’s rearview mirror. With a dive to the bottom lane that made fans gasp, Heim cleared the Cup Series star by a razor-thin 0.145 seconds as they crossed the stripe.

2. Why Corey Heim is the Most Dangerous Part-Timer in NASCAR

To understand the sheer magnitude of this upset, you have to look at who is sitting behind the wheel. Corey Heim is not your average underdog. He is the 2025 Truck Series champion. Last year, he rewrote the history books, racking up a staggering 12 victories and shattering Mike Skinner’s 1996 record for the most laps led in a single season. Yet, inexplicably, the 23-year-old phenom finds himself running a part-time schedule in 2026. Let that sink in. The reigning champion does not have a full-time seat. Naturally, Heim is driving with a massive chip on his shoulder, and Darlington was just the latest venue for his revenge tour. Taking down a seasoned Cup driver like Chastain in a part-time ride isn’t just impressive; it is a loud, undeniable statement to every team owner in the garage. This marked Heim’s 24th career Truck Series win in just 91 starts—a batting average that is frankly absurd. If Heim was riding high on pure adrenaline, Chastain was left scratching his head in the pits. You almost had to feel bad for the guy. He did everything right, hitting his marks and surviving the chaos, only to have a part-timer on scuffed tires ruin his Friday night. “I have no idea what just happened,” Chastain told reporters after climbing out of his truck, staring blankly at the asphalt. “We did so much right… Bummer.” “Bummer” might be the understatement of the century. Chastain left the door open on the bottom groove, and Heim didn’t hesitate to kick it off the hinges. Even Heim was surprised by the late-race gift. “I didn’t think we could win from where we were at,” Heim confessed in Victory Lane, holding a massive novelty check. “I was shocked Ross gave me the bottom with fresher tires.”

3. What Is Next in the Triple Truck Challenge?

Aside from the trophy and the bragging rights, this victory came with a very lucrative piece of hardware: a $50,000 bonus from the Triple Truck Challenge. And the gravy train might not be stopping in South Carolina. Because he won the first leg of the challenge, Heim is now eligible for a massive $100,000 payday if he can pull off another victory in the next event at Rockingham Speedway on April 3. If he somehow sweeps the challenge by winning at Bristol Motor Speedway the following week, he could be walking away with $150,000 in bonus money. Corey Heim is proving that you don’t need a full-time schedule to be the main character of the NASCAR Craftsman Truck Series. You just need four fresh tires, a fast Toyota, and a whole lot of guts.
