Kyle Larson & William Byron Team Up to Conquer the Truck Series – Is This a Championship Takeover?

The 2025 NASCAR Craftsman Truck Series is about to get a serious dose of superstar power. Kyle Larson and William Byron, two of NASCAR’s biggest names, are set to share the No. 07 Chevy Silverado for Spire Motorsports in three high-stakes races. With their Cup Series dominance and proven track records, these two Hendrick Motorsports teammates are gearing up to shake up the competition in the truck series.

Breaking Down the Schedule: Three Key Races

Both drivers will take turns behind the wheel in some of the biggest Truck Series events of the season:

• Kyle Larson will race at Homestead-Miami Speedway (March 21) in the Baptist Health 200 and at Bristol Motor Speedway (April 11) in the WEATHER GUARD Truck Race.
• William Byron will take charge at Martinsville Speedway (March 28), a track where he already boasts a Truck Series victory.

With their winning pedigree and relentless drive, the NASCAR world is on edge, anticipating the results of this blockbuster collaboration.

Kyle Larson: The Versatile Champion Looking for More

A 29-time NASCAR Cup Series winner and the 2021 Cup Series champion, Kyle Larson is no stranger to dominating on multiple levels. He’s already conquered both Homestead and Bristol in the Cup and Xfinity Series, but there’s still one piece missing—a Truck Series victory at these legendary venues.

“I love racing at Homestead-Miami and Bristol,” Larson said. “Hopefully, we can put on a great show and battle for the victories.”

Beyond the Truck Series, Larson is also locked in for a NASCAR Xfinity Series appearance at both Homestead and Bristol, making him a triple-threat contender for a weekend sweep—something only Kyle Busch has ever achieved.

William Byron: The Martinsville Master Returns to His Winning Roots

William Byron has been on fire in recent seasons. The 14-time NASCAR Cup Series winner has cemented himself as a dominant force, with back-to-back DAYTONA 500 victories (2024 & 2025). Now, he’s looking to rekindle past Truck Series success at Martinsville—where he last won in 2022 with Spire Motorsports.

“It’s been a couple years, but I’m excited to get back in the Truck Series,” Byron said. “Last time I ran a truck at Martinsville, we won. Hopefully, we can do that again.”

Byron’s success in the Cup Series at Martinsville, combined with his previous Truck Series dominance, makes him a top contender to take the checkered flag once more.

The Numbers Don’t Lie: A Look at Their Truck Series Success

While both Larson and Byron are Cup Series elites, their Truck Series records show why Spire Motorsports is banking on them for victories:

• William Byron: 8 Truck Series wins in 29 starts, including 7 wins in 2016—a dominant season that launched his NASCAR career.
• Kyle Larson: A second-place finish at Homestead (2014) stands out, proving his capability to fight for the win in the Truck Series.

With these two behind the wheel, Spire Motorsports is in prime position to chase victories and shake up the championship battle.

The Power Behind the Partnership: HendrickCars.com & Spire Motorsports

This powerful collaboration isn’t just about putting two Cup Series stars in a truck—it’s also about strategic sponsorship and team development.

HendrickCars.com, owned by Rick Hendrick, will be backing both Larson and Byron in their Truck Series campaigns. In addition, the company is sponsoring two other Spire Motorsports entries, featuring rising NASCAR stars Corey Day and Rajah Caruth.

With the Hendrick-Spire alliance, the No. 07 Chevy Silverado will have elite resources, making it a serious threat in all three events.

Can Larson Make NASCAR History? The Tripleheader Challenge Awaits

Few drivers can handle competing in multiple series in one weekend, but Kyle Larson thrives on it.

If he can win all three races at Bristol Motor Speedway—the Truck Series, Xfinity Series, and Cup Series events—he’ll become only the second driver in NASCAR history to accomplish the feat. The only driver to have done it? Kyle Busch (2010 & 2017).

With Larson’s raw talent and experience, he’s a serious contender to pull off this historic achievement.

What’s at stake for Larson & Byron?

Kyle Larson’s Tripleheader Chase
Larson isn’t just aiming for Truck Series glory—he’s looking to make history. Alongside his Truck Series events, he will also race in the Xfinity Series for Hendrick Motorsports at Homestead and Bristol.

Only Kyle Busch has ever swept a NASCAR tripleheader (winning Cup, Xfinity, and Truck races on the same weekend). Larson could become just the second driver to achieve this feat.

William Byron’s Bid to Reignite Truck Series Success
For Byron, this is a return to familiar territory. His last Truck Series win came at Martinsville in 2022, and he’s looking to recreate that magic.

“It’s been a couple of years since I raced a truck, but I’m ready to get back out there,” Byron said. “Last time at Martinsville, we won. Hopefully, we can do that again!”

With back-to-back Daytona 500 wins (2024 and 2025) in the Cup Series, Byron’s confidence is sky-high. A Truck Series win could add even more momentum to his season.

Why This Matters: The Future of NASCAR’s Top Stars

Larson and Byron stepping into the Truck Series isn’t just about winning races—it’s about honing their skills, building momentum, and influencing the next generation of NASCAR talent.

Both drivers know that track time in any series pays off, and their experience in Cup, Xfinity, and Trucks gives them an edge over competitors who stick to just one series.

For Spire Motorsports, this is a golden opportunity to elevate their team by partnering with two of the best drivers in the sport. The impact of having Hendrick-backed superstars in their trucks will likely ripple through the entire organization.

Final Lap: What to Expect in 2025

With Kyle Larson and William Byron on board, expect fireworks in the NASCAR Craftsman Truck Series in 2025. Their caliber, experience, and hunger to win make them instant favorites in these three races.

• Can Byron repeat his Martinsville Truck Series triumph?
• Will Larson finally conquer Homestead and Bristol in a truck?
• Can Larson make NASCAR history with a Bristol sweep?

NASCAR fans won’t want to miss a second of the action as these two Cup Series superstars drop down into the Truck Series and shake things up.
