For the first time at the Mac Tools U.S. Nationals, Stock and Super Stock Class eliminations were placed on ladders. In response to the positive feedback received from the Stock and Super Stock competitors, NHRA will continue to ladder class eliminations. Ladders will be generated as a result of the qualifying runs made prior to the first round of class eliminations. Competitors who have not made a qualifying run before the first round of class eliminations will be placed on the bottom of their class ladder. In the event of a three car ladder if a competitor does not show for round one, the two remaining competitors will be paired as a final.
