Event changes
The race events in Topeka, Kansas and Petersburg, Virginia have switched dates for this year, with the Virginia NHRA Nationals taking place in May and the Menards NHRA Heartland Nationals in June. In the Countdown, the race events in Charlotte, North Carolina and Ennis, Texas have switched weekends for this year in October. All other events during this season remain on the same schedule, although a couple of them either moved up or down a weekend. Scheduling changes made primarily to avoid NASCAR events in the markets.

NHRA Pro Stock Car only raced in 18 events this year, down from 24 events the year prior. Four of the races that they did not participate in featured non-championship exhibition Mountain Motor Pro Stock Cars (over-500 ci engines with carburetors). Those races are Houston, Charlotte 1, Bristol and Epping.
