With Kyle Busch's dominant truck getting crunched, Matt Crafton survived a wild finish to win his first Craftsman Truck Series race at Concord.

Crafton avoided the mayhem over the final laps Friday night, pulling away in a green-white-checkered finish to win at Lowe's Motor Speedway. It was Crafton's first win in 178 career starts dating to 2000.

Crafton successfully blocked Chad McCumbee's pass attempt in turn 3 of the final lap and pulled away. Brendan Gaughan finished third, followed by Erik Darnell and Rick Crawford.

Busch finished 13th after getting caught in a wreck with 29 laps to go started by points leader Ron Hornaday, who later lost his cool after he was hit from behind by Todd Bodine and finished 23rd.

Busch, the 23-year-old rising star, was hoping to win four races at the track in 10 days. Hours after he captured the pole for today's Sprint Cup All-Star race, Busch started from the pole in his No. 51 Toyota. He led 86 of the 134 laps and appeared unbeatable until running into bad luck.

BIFFLE ISN'T QUITTING: Despite his harsh comments about his race team at Darlington Raceway, Greg Biffle said he's still committed to signing a contract extension with Roush Fenway Racing.

"Nothing has changed," Biffle said Friday at Lowe's Motor Speedway. "I don't understand. I don't quit. I'm not going to quit on my guys. I'm not going to give up."

Biffle is in the final year of his contract with Roush and has maintained since last season that he intends to sign an extension with the team. But talks have been slow, and his intent came into question last Saturday night when he blasted his team because his pole-winning car broke down after leading 95 laps at Darlington.
