The qualifying outcomes from the Professional 275 class at the US Street Nationals determine the starting lineup for eliminations. This specific racing category features purpose-built race cars utilizing 275-width drag radial tires, competing for top speed and elapsed time over a quarter-mile distance.

These qualifying performances are critical for race strategy and provide valuable data for teams to fine-tune their vehicles. A strong qualifying position often correlates with a higher probability of success in eliminations. The data gathered during qualifying, including elapsed times, speeds, and 60-foot times, allows teams to make adjustments to suspension settings, engine tuning, and other performance variables. Historically, this class has been a showcase for cutting-edge drag racing technology and driver skill, with qualifying often producing exceptionally close competition.
