FORT WORTH, Texas -- The No. 1 Chevrolet driven by Martin Truex Jr. failed a post-race inspection when NASCAR officials found the height of the car was too low.
The violation was discovered because the No. 1 Chevy was the random car selected for inspection after the Dickies 500. Truex finished 14th.
Any penalties for the team will be announced on Tuesday, NASCAR officials confirmed.
NASCAR also is taking three cars back to the Research and Development Center in Concord, N.C. -- the No. 2 Dodge of race winner Kurt Busch, the No. 24 Chevy of Jeff Gordon, who finished 13th, and the No. 5 Chevy of Mark Martin, who finished fourth.
NASCAR also will take three engines to the R&D Center -- the No. 2 Dodge, the No. 11 Toyota motor of driver Denny Hamlin, who finished second, and Gordon's.
The winning car and the engines from the top two finishers always are inspected in the R&D Center.
