Ross Chastain finalizes 2026 NASCAR O’Reilly Auto Parts Series part-time schedule

“We’re excited to welcome Ross to the #32 for these races,” team owner Jordan Anderson said. “He’s a proven winner at the Cup level, but he’s also someone who understands what it takes to grow within a team and build results through hard work. His experience and perspective will be valuable for everyone in our organization.”

Ross Chastain has a full schedule in 2026

That brings Chastain’s 2026 race tally to 54. JR Motorsports previously announced that Chastain would run a four-race schedule in the No. 9 Chevrolet, while Truck team Niece Motorsports has Chastain on board for eight races in the No. 45 Silverado. Of course, Chastain will be behind the wheel of the No. 1 Chevrolet for all 38 Cup races.

Chastain made five O’Reilly Auto Parts starts in 2025, compiling four top 5s. He will look to get back in Victory Lane this season; he last won in the series in 2019.

Ultimately, Chastain’s main focus will be on the Cup side of things. Chastain is coming off a season in which he captured a Crown Jewel win in the Coca-Cola 600 at Charlotte Motor Speedway, clinching him a spot in the playoffs. Chastain was eliminated after the Round of 12 cutoff race at the Charlotte ROVAL.

This upcoming campaign brings along a new championship format. The win-and-in, elimination style format is gone. A revamped “Chase” style format is back, featuring the top 16 highest-point earners throughout the regular season. The champion will be decided after a 10-race postseason.

Consistency will be key. It will force Chastain and the rest of the field to make calculated decisions every race day.
