Kevin Harvick On Rivalry With Kyle Busch: 'Best Thing That Happened In My Career'

In the 2010s drivers — and fans — had to pick a side: Chevrolet with Kevin Harvick Incorporated or Toyota with Kyle Busch Motorsports, creating intense team-based rivalries.
Despite a heated on-track feud (including a big Dover wreck in 2005), Harvick helped Busch build Kyle Busch Motorsports, sharing shop knowledge and resources even as Busch hired some of his people.
The two pushed each other on the track for years, grew to respect and enjoy time off-track, and Harvick is now fondly remembering Busch after his sudden passing.
