Haas Factory Team has hired Aaron Kramer to be the crew chief for driver Cole Custer and the No. 41 NASCAR Cup Series team in 2025. Custer will drive the No. 41 Ford for the Haas Factory Team in 2025 after the dissolution of Stewart-Haas Racing’s four-car NASCAR Cup Series operation at the end of the season.

Kramer will come to Haas Factory Team after the 2024 season from RFK Racing, with whom Haas Factory Team will have a technical alliance. The 35-year-old from Wellsville, New York is currently the lead race engineer for Cup Series driver Chris Buescher and the No. 17 team.

Kramer has been with RFK since 2016, rising from an electrical and data systems engineer who oversaw the team's advanced track simulator rig to lead race engineer on RFK's No. 60 NASCAR Xfinity Series team in 2018. Kramer was promoted to Cup in 2019, working as the secondary race engineer for two years with the No. 6 team and driver Ryan Newman before moving to the No. 17 team in 2021 with Buescher.
