NASCAR issued a bulletin to Sprint Cup, Xfinity and Camping World Truck teams with changes to the rule book Wednesday.
Among the changes is a rule the requires a driver, crew chief and spotter to have radio communication, a new single rear-end differential assembly rule and a single transmission rule.
Previously, teams could change as many gears as they wanted but they had to be the right ratio. Now, a single rear end differential assembly rule will be enforced at all events except at Martinsville Speedway, road course events, the Daytona 500, the Sprint Showdown and the NASCAR Sprint All-Star race.
Martinsville and road courses are hard on gears. Because of the number of events leading up to the Daytona 500, teams can make a change. It’s also easy to break a gear in All-Star qualifying.
This rule should eliminate qualifying gears.
NASCAR stated that failure to comply with this rule could result in loss of practice time, loss of opportunity to qualify and confiscation of the rear end differential assembly, along with any other actions the series director deems necessary.
NASCAR formalized that a driver, crew chief and spotter must be able to communicate on the radio during an event.
NASCAR stated that effective Jan. 1, 2016 teams will be permitted only one transmission change after qualifying and before the race for events at Pocono Raceway and road course events.
Other changes included adding the new qualifying format for super speedways previously announced and other technical updates.
Kyle Busch moved closer to the top spot after his win Sunday at WWT Raceway, but William Byron keeps hold of No. 1 after another top-10 run.
The series heads to Sonoma Raceway this weekend, the second race of the season on a road course.

Dropped out: Chase Elliott (5th), Tyler Reddick (8th)
Despite Richard Childress and Austin Dillon saying that Austin Cindric intentionally wrecked Dillon late in Sunday’s Cup race at WWT Raceway, NASCAR will not penalize Cindric.
Elton Sawyer, NASCAR senior vice president of competition, said Tuesday on SiriusXM NASCAR Radio that there would be no penalty to Cindric after reviewing the contact.
Dillon and Childress were upset about the incident, which brought out the caution on Lap 220 of the 243-lap race. Dillon said NASCAR should suspend Cindric for the contact, just as NASCAR suspended Chase Elliott one race for hooking Denny Hamlin in the Coca-Cola 600.
Contact between the left front of Cindric’s car and the right rear of Dillon’s car sent Dillon up the track into Ricky Stenhouse Jr. Dillon finished 31st. Cindric continued and placed 13th.
Dillon told Frontstretch.com: “I was wrecked intentionally by (Cindric), hooked right just like Chase and Denny and Bubba’s deal (in wrecking Kyle Larson at Las Vegas in 2022). He better be suspended next week.”
Childress said: “(Dillon) had drove up to about 10th until (Cindric) wrecked him in there on purpose, sort of a payback.”
Sawyer said a review of the incident included viewing video and data.
“We didn’t see anything — and haven’t seen anything — that really would rise to a level that would be a suspension or a penalty,” Sawyer said. “It looked like hard racing. One car coming up a little bit and another car going down.
“As we said last week, we take these incidents very serious when we see cars that are turned head-on into another car or head-on into the wall. I spent a lot of time (Monday) looking at that, looking at all the data, looking at TV footage and just deemed this one really hard racing.”
Sawyer said NASCAR plans to talk to both Cindric and Dillon “to make sure we’re all in a good place as we move forward to Sonoma.”
Kyle Larson is among seven Cup drivers entered in Saturday’s Xfinity Series race at Sonoma Raceway.
The race marks the first time the Xfinity Series has competed at the California road course. Teams will get 50 minutes of practice Friday because this is a new event on the schedule. That additional time will give those Cup drivers more laps on the 1.99-mile road course.
Here is a look at what Xfinity rides the Cup drivers will pilot this weekend:
The race is scheduled to start at 8 p.m. ET Saturday.
The ARCA Menards Series West also is competing this weekend at Sonoma Raceway. Cup driver Ryan Preece is entered in that event. Xfinity drivers Cole Custer, Riley Herbst, Sammy Smith and Parker Retzlaff also are entered in that race, which will be held at 6:30 p.m. ET Friday.
Winners and losers from Sunday’s Cup race at WWT Raceway:
Kyle Busch — Wins the pole, leads the most laps and holds the field off over the last five restarts to win the race. He scored six playoff points, giving him 16 on the season, second only to William Byron’s 17. Busch left Joe Gibbs Racing after last season for Richard Childress Racing. Busch’s three wins this year equals what JGR has done so far.
Ryan Blaney — His sixth-place finish moved him into the points lead. He last led the points after the spring 2022 Richmond race. Blaney also won a stage Sunday to collect another playoff point. He has seven this season.
Kyle Larson — Fourth-place finish was a big turnaround after struggles earlier in the race. It has not been easy for this team the last few weeks. He has three top-five finishes and four finishes of 20th or worse in the last seven races.
Daniel Suarez — His seventh-place finish moved him up two spots to 16th in the standings, the final playoff transfer spot at this time.
Ross Chastain — He finished 22nd for his third consecutive result outside the top 20. He entered the weekend leading the points and fell to fifth afterward. He is 29 points behind new series leader Ryan Blaney with 11 races left in the regular season.
Tyler Reddick — Rebounded from an early spin to lead but had his race end after a brake rotor failed. He was one of four drivers eliminated by brake rotor failures. The others were Carson Hocevar, Bubba Wallace and Noah Gragson.
