- With the new flange-fit composite bodies being made mandatory in the 2019 season, Dodge left the Xfinity Series after the 2018 season, as the former Team Penske Challengers (nicknamed "Zombie Dodges" due to their lack of factory support since 2013) used by smaller teams were deemed ineligible due to their steel bodies. This also means that Dodge would have no representation in NASCAR's three major series for the first time since 1994.
- On August 23, 2018, NASCAR announced that Cup drivers competing in Xfinity Series events would no longer be eligible to earn playoff bonus points for the cars that they were driving.

- The flange-fit composite bodies, first introduced in 2018, will be made mandatory for all races in the 2019 season.
- On February 4, 2019, NASCAR announced a new post-race inspection rule in all three series, where race-winning teams found to be in violation of the rule book will automatically be disqualified. Following a race, the first-place and second-place teams, along with at least one randomly selected car, will undergo post-race inspection. The inspection should take between 90 minutes and two hours to complete before the race winner is officially declared. The car that fails the inspection will receive last-place points and will be stripped of playoff and stage points.
- At the 2019 Camping World 300 at Chicagoland Speedway on June 29, 2019, Christopher Bell became the first NXS driver to be disqualified under this rule after his car was discovered to be too low on the front during post-race inspection. As a result, his finish was demoted from third place to 38th place. Bell became the first NXS driver to be disqualified since Dale Jarrett in 1995.
- At the 2019 Circle K Firecracker 250 at Daytona International Speedway on July 5, 2019, A. J. Allmendinger became the second NXS driver to be disqualified after his third-place finishing car failed an engine vacuum check during post-race inspection.

- At the 2019 Sport Clips Haircuts VFW 200 at Darlington Raceway on August 31, 2019, Denny Hamlin was stripped of his win after his car failed to meet height requirements during post-race inspection. As a result, second-place finisher Cole Custer was declared the official race winner.
- At the 2019 Rhino Pro Truck Outfitters 300 at Las Vegas Motor Speedway, Ryan Sieg was disqualified after his 14th-place finishing car failed to meet height requirements during post-race inspection. The violation, however, did not affect Sieg's standing as one of the 12 qualifying drivers for the NXS Playoffs.
- On February 4, 2019, NASCAR announced a change in the qualifying schedule procedures for the majority of its tracks. For short tracks and intermediate speedways, the first round will be shortened from 15 minutes to 10 minutes, while the second and third rounds will remain at 10 and five minutes, respectively. The downtime intervals at all tracks will be reduced from seven minutes to five minutes. Superspeedway qualifications will retain their untimed two-round intervals of single-lap qualifying while road courses will continue to use two qualifying rounds: 25 minutes for the first round and 10 minutes for the final round.
- On May 1, 2019, following continued gamesmanship and other actions causing multi-car qualifying to become "untenable," NASCAR formally returned to single-car qualifying at all oval tracks. Knockout-Style qualifying would be kept at Watkins Glen, Mid-Ohio, Road America, and the Charlotte Motor Speedway Roval.
- At oval tracks 1.25 miles and larger, each car will get a single timed lap.
- At oval tracks 1.25 miles and smaller, each car will get two timed laps with the faster lap counting as their official time.
- The qualifying order draw will be determined in part by the previous race's starting lineup. The top 20 starters from the previous race will draw to take their qualifying lap in positions 21–40 (the second half of qualifying). The remainder of cars will draw to qualify in positions 1–20.
- The next car will be sent once the preceding car takes the white flag. This should ensure qualifying is completed in roughly 40 minutes baring any interruptions for crashes, debris, or weather.
- There will be two-minute TV breaks built into qualifying to ensure every car gets covered live during the session.
- Broadcasters FOX and NBC have committed to using ghost car graphics and impose other technologies to make the session more exciting to TV viewers.
- Each car must complete their lap for the session to be counted, otherwise all times will be erased and cars will start by owner points.
The schedule, consisting of 33 races, was announced on June 13, 2018. Similar to the Monster Energy Cup Schedule, there are no changes from 2018 to 2019; However, both the regular-season finale at Las Vegas and the playoff race at Texas will be night races. The Charlotte Roval round, which was originally 200 kilometres (120 mi) long, was increased to 250 km (160 mi) for 2019.
Bonus money Dash 4 Cash races indicated in BOLD. Qualifying race for first Dash 4 Cash race in Italics.
