Bumgarner spent the last 18 years at Hendrick Motorsports, where he worked on cars for Terry Labonte, Jeff Gordon, and Kyle Busch. In 2007 he was crew chief on Busch’s No. 5 Chevrolet in the Nationwide Series. Together they compiled four wins, 14 Top-5, 16 Top-10s and three pole awards in 2007.
Bumgarner’s jump into NASCAR came in 1992 with a team owned by Kenny Bernstein. Three years later he began employment at Hendrick Motorsports.
Bumgarner is from Huntersville, N.C. His naming as crew chief for Kahne and Sweet fills one of the final remaining slots in the JRM line-up for 2013. Greg Ives, who similarly arrived to JRM via Hendrick Motorsports, will head the No. 7 TaxSlayer.com/Hellmann’s team and driver Regan Smith.
