Joliet, Ill. -- Brian Vickers has won the pole position for Saturday's LifeLock 400.com Sprint Cup race after a qualifying speed of 184.162 miles per hour.
Vickers is the eighth different pole winner in nine races at Chicagoland, where qualifying was rained out last year.
His tour around the Chicagoland Speedway in Joliet, Ill., marked the fifth time this season he earned the right to be the lead driver at a Sprint Series race and third straight.
He also won it before the Save Mart 350 in Sonoma, Calif., and the LifeLock 400 in Brooklyn, Mich.
"That car was just unbelievable," he said Thursday about his No. 83 Red Bull Toyota. "It was good when we unloaded it, and (the team) made it better."
