Greg Biffle can thank Roush Racing teammate Matt Kenseth for his win Sunday afternoon at Dover International Speedway.

Before the race, Kenseth's pit crew came up with a new shock package for Biffle that gave him the perfect setup.

Biffle passed Elliott Sadler for the lead on lap 241, then pulled away from the field to win the MBNA RacePoints 400, his fourth victory of the 2005 season.

Roush Racing had a field day, taking four of the top nine spots in the 43-car starting grid.

Jeff Gordon, Ricky Rudd, Ken Schrader and Dave Blaney were involved in crashes early in the race that sent them to the garage.

Sunday's race marked the halfway point toward the 26-race cut, after which only the top 10 drivers or those within 400 points of the leader will compete for the championship over the final 10 events.
