Harvick, who led 166 of the 200 laps, had to hold off a late challenge by Carl Edwards to get his second win this season on the Busch circuit.
"We kind of geared up for short runs, hoping it would come down to that kind of run at the end," Harvick said. "I knew (Edwards) was going to come after me on the bottom, try to get underneath us, and we were able to hold him off."
Harvick's win made him the 21st driver in as many races to win at the New Hampshire International Speedway, in his 28th career Busch race victory.
