Chad Haney is the crew chief for the No. 21 Chevrolet in the NASCAR O’Reilly Auto Parts Series with driver Austin Hill. 2026 marks the Fairmont, West Virgina native’s second year paired with Hill. He brings to the role more than 30 years of professional motorsports experience.

In their first year paired together in 2025, Haney guided Hill and the No. 21 team to four race wins, including three on drafting-style tracks to help Hill surpass the record for wins on drafting tracks set by NASCAR Hall of Famers Dale Earnhardt and Tony Stewart. In addition to drafting wins at Atlanta Motor Speedway (February) and Talladega Superspeedway (April and October), Haney guided Hill to a short track win at Martinsville Speedway in March. In all, the No. 21 team earned 13 top-five finishes, 18 top-10 finishes and finished fourth in the owner’s point standings.

Prior to taking the helm of the No. 21 team in 2025, Haney was RCR’s head mechanic in the NASCAR O’Reilly Auto Parts Series, managing the build and development of the organization’s cars to ensure parity among RCR and NASCAR O’Reilly Auto Parts Series alliance partners.

Haney has worked as a car chief and mechanic at the highest levels of the sport, including stints as a car chief in the NASCAR Cup Series for drivers such as Aric Almirola, Clint Bowyer, Kurt Busch, Austin Dillon and Kevin Harvick. Haney’s resume includes victories at some of NASCAR’s most prestigious races, including a Daytona 500 win with Busch in 2017 and a Coca-Cola 600 win with Harvick in 2011. He was part of the team that returned the No. 3 Chevrolet to the NASCAR Cup Series in 2014 with Dillon, notably sitting on the pole for that year’s Daytona 500.

Haney’s career at RCR first began in 2005, but beginning in 2015, he took an eight-year hiatus from the team to work as a car chief at Stewart-Haas Racing. Haney also worked for Kevin Harvick, Inc. as a crew chief for Harvick’s short track racing endeavors during his leave from RCR.

From 2014-2009, Haney was a car chief at RCR in the NASCAR Cup Series, working with Dillon (2015, 2014), Harvick (2013, 2012), and Bowyer (2011, 2010, 2009). Prior to his Cup career, Haney was a car chief in the NASCAR O’Reilly Auto Parts Series with the No. 2 Chevrolet driven by Bowyer (2008, 2006) and the No. 29 Chevrolet driven by Jeff Burton and Scott Wimmer (2007). He started at RCR as a front-end mechanic for the No. 21 Chevrolet driven by Harvick and Brandon Miller in the O’Reilly Auto Parts Series in 2005.

A racer himself, Haney spent several years honing his skills as a dirt late model racer before giving up the steering wheel for a wrench. He was a crew chief in the dirt late model world working for Rocket Chassis before moving to North Carolina to pursue a career in NASCAR in 2004. A love of motorsports came early for Haney, who started going to dirt tracks with his father as a young child. Those early experiences led to his first job in the sport, working on dirt cars when he was just 15 years old.

Haney spends his free time helping his son, a two-time champion, race quads.

A West Virginia native, Haney resides in Lexington, N.C. with his wife Buffy and son Cameron.
