There will be a change atop the pit box for the No. 1 Trackhouse Racing Team Chevrolet next season. Brandon McSwain, who has worked as an engineer for the No. 24 Hendrick Motorsports team for the past six years, will replace Phil Surgen.
Chastain has worked with Surgen since the 2021 season when he still drove for Chip Ganassi Racing, and has won all six of his Cup races with the same crew chief. The duo nearly won the 2022 Cup Series championship, and most recently earned a crown jewel victory in the 2025 Coca-Cola 600.
