RFK Racing on Monday parted ways with Jeremy Bullins, crew chief for Brad Keselowski’s No. 6 Ford. The amicable split precedes Kansas’ Hollywood Casino 400, 3 p.m. ET on USA Network, HBO Max, MRN Radio, and SiriusXM NASCAR Radio.
Bullins leaves to pursue a new opportunity. Mike Skarbowski assumes crew-chief duties immediately, appearing on NASCAR’s roster portal and the current Cup Series entry list for the No. 6 Ford.
Skarbowski’s RFK background includes team-manager responsibility across the organization’s three cars. Previously a Trackhouse Racing race engineer, he brings Next Gen experience and operational familiarity that should aid a swift transition.

Bullins joined RFK for 2025, reuniting with Keselowski after their Team Penske stint. He has 10 Cup wins, five with Keselowski during 2020–2021, highlighting a proven driver–crew chief partnership.
Under Bullins, Ryan Blaney won three times, while Austin Cindric and Harrison Burton each claimed one victory. Blaney’s recent form, notably his Bristol night showing, underscores Bullins’ impact across multiple drivers.
Keselowski has missed the postseason in each of the past two seasons and currently sits 18th in the 2026 standings. The change targets improved execution in qualifying, strategy calls, and pit-road efficiency.
The timing compresses setup and simulation cycles before Kansas. Yet Skarbowski’s internal knowledge of RFK processes, personnel, and inventory should minimize disruption as responsibilities shift from management to on-stand leadership.
Kansas becomes an immediate benchmark for the No. 6 group. Track position and caution management typically decide outcomes, and recent Bristol results underline the tight competitive spread entering this stretch.
Beyond Cup, Bullins has 21 wins in 100 starts in the NASCAR O’Reilly Auto Parts Series, reinforcing a résumé that remains strong even as RFK adjusts course with new leadership.
