Haas Factory Team will expand to three full-time cars in the NASCAR O’Reilly Auto Parts Series in 2027, and Dean Thompson will join the organization to drive its third entry on a multi-year deal. The 24-year-old will move from Sam Hunt Racing’s Toyota program to a Haas Chevrolet, with team president Joe Custer announcing the move at Iowa Speedway on Saturday.
Thompson is in his second full-time season in the series and has 57 career starts, one top-five finish and 10 top-10s. He posted eight top-10s in 2025 and has added two more through the first 22 races of 2026, with his best result this year a sixth-place finish at Talladega in April. Before moving up, he ran in the NASCAR CRAFTSMAN Truck Series from 2022 to 2024, making 70 starts and earning 11 top-10 finishes.
Custer said Thompson has shown strong progression and said he will compete at the highest level. Thompson said his long relationship with Joe Custer and Cole Custer helped lead to the opportunity, and he said he is excited to join Haas Factory Team and race for wins and a championship. Thompson Pipe Group and MCM Transportation will serve as primary partners on the Chevrolet, and Haas said the car number and crew chief will be announced later. The team currently fields two full-time O’Reilly Series cars for Sheldon Creed and Sam Mayer, and it remains committed to its single-car Cup Series operation with Cole Custer.
